Алкин-ПЭГ4-фосфорамидит — представляет собой фосфорамидит на основе тетраэтиленгликоля с терминальной тройной связью и может использоваться для синтеза различных функционализированных олигонуклеотидов. Алкиновый фрагмент в синтезированных молекулах вступает в реакции Click Chemistry с соединениями, содержащими азидную группу в присутствии солей меди(I), приводя к различным олигонуклеотидным конъюгатам, например с красителями, пептидами или гликанами. Выход полученных подобным образом соединений довольно высок, а выделение и очистка продуктов зачастую проще по сравнению с молекулами, полученные в результате взаимодействия амино-модифицированных олигонуклеотидов с активированными эфирами, например, красителей. Важной характеристикой Click Chemistry реакций является их биоортогональность, поскольку ни терминальные алкиновые, ни азидные функциональные группы обычно не присутствуют в биомолекулах.

Тетраэтиленгликольный линкер, входящий в структуру фосфорамидита, обеспечивает повышенную гидрофильность, а также снижает токсичность и иммуногенность синтезированных конъюгатов.

炔烃-PEG4-亚磷酰胺是一种基于四甘醇的亚磷酰胺，具有末端三键，可用于合成各种功能化的寡核苷酸。合成分子中的炔烃片段在铜 (I) 盐存在下与含有叠氮基的化合物进入 Click Chemistry 反应，从而产生各种寡核苷酸缀合物，例如与染料、肽或聚糖。以这种方式获得的化合物的产率非常高，与由氨基修饰的寡核苷酸与活化的酯（例如染料）相互作用获得的分子相比，产物的分离和纯化通常更简单。 Click Chemistry 反应的一个重要特征是它们的生物正交性，因为末端炔烃和叠氮官能团通常不存在于生物分子中。

包含在亚磷酰胺结构中的四甘醇接头提供了增加的亲水性，并且还降低了合成缀合物的毒性和免疫原性。

TET phosphoramidite for synthesis of fluorescently labeled oligonucleotides, pure 6-isomer.

TET (tetrachlorofluorescein) is a green-fluorescent fluorescein derivate (absorption maximum at 519 nm, emission maximum at 535 nm).

TET phosphoramidite is used for synthesis of fluorescently-labeled primers and hybridization probes for qPCR. TET can be used with DusQ1 fluorescence quencher (can be used with 500 Å DusQ1 CPG 500).

5’-labeled primers are used with non-labeled reverse primers for microsatellite amplification via RCR followed by fragment analysis. TET-labeled amplification products can be analyzed using various sequencers for capillary electrophoresis, including ABI PRISM® 310 Genetic Analyzer.

TET 亚磷酰胺用于合成荧光标记的寡核苷酸，纯 6 异构体。

TET（四氯荧光素）是一种绿色荧光荧光素衍生物（最大吸收波长为 519 nm，最大发射波长为 535 nm）。

TET 亚磷酰胺用于合成荧光标记的引物和用于 qPCR 的杂交探针。 TET 可与 DusQ1 荧光猝灭剂一起使用（可与 500 Å DusQ1 CPG 500 一起使用）。

5′ 标记的引物与未标记的反向引物一起使用，通过 RCR 进行微卫星扩增，然后进行片段分析。 TET 标记的扩增产物可以使用各种毛细管电泳测序仪进行分析，包括 ABI PRISM® 310 遗传分析仪。

Recommendations for using the reagent:

使用试剂的建议：

Condensation: 3 min.

Deprotection: standard conditions with 25% aqueous ammonium solution; deprotection time depends on nucleic base profile and their protective properties (deprotection for 17 hours at 55°C removes all protection groups from standard nucleic acids). AMA (1:1 mixture of concentrated aqueous ammonium/40% aqueous methylamine) can be used with ~5% non-fluorescent by-product forming. To avoid formation of the by-product, start deprotection with ammonium (30 min at room temperature), then add an equivalent volume of 40% aqueous methylamine solution and continue deprotection as usual with AMA (10 min at 65°C).

冷凝：3 分钟。

脱保护：标准条件用25%铵水溶液； 脱保护时间取决于核酸碱基谱及其保护特性（在 55°C 脱保护 17 小时会去除标准核酸中的所有保护基团）。 AMA（浓铵水溶液/40% 甲胺水溶液的 1:1 混合物）可用于形成约 5% 的非荧光副产物。 为避免形成副产物，用铵开始脱保护（室温下 30 分钟），然后加入等量体积的 40% 甲胺水溶液，并像往常一样用 AMA 继续脱保护（65°C 下 10 分钟）。

This phosphoramidite is used for synthesis of oligonucleotides 5’-labeled with TAMRA.

TAMRA (carboxytetramethylrhodamine) is a xanthene dye from the rhodamine family with emission in the orange spectrum range (maximum at 563 nm). This fluorophore is traditionally used as a FRET-acceptor (and a quencher) in a pair with fluorescein (FAM) due to significant overlapping of their spectra. Thus, this phosphoramidite is convenient for the synthesis of dual-labeled probes TaqMan, which contain 5’-terminal TAMRA and FAM in the middle of the sequence or at the 3’-end (using Fluorescein dT Phosphoramidite and FAM CPG, respectively).

TAMRA 5’-labeled oligonucleotides are commonly used for quantitative PCR and fragment analysis (for example, for microsatellite marker analysis) because the equipment available has a detection channel for TAMRA frequently.

The TAMRA dye is not stable in the presence of ammonium and sterically non-hindered primary amines, so it is strongly recommended to follow specified conditions for labeled oligonucleotide deprotection.

该亚磷酰胺用于合成 5′ 标记的 TAMRA 寡核苷酸。

TAMRA（羧基四甲基罗丹明）是罗丹明家族的一种呫吨染料，在橙色光谱范围内发射（最大波长为 563 nm）。这种荧光团传统上用作 FRET 受体（和猝灭剂），与荧光素 (FAM) 成对使用，因为它们的光谱有显着重叠。因此，这种亚磷酰胺便于合成双标记探针 TaqMan，该探针在序列中间或 3′ 端含有 5′-末端 TAMRA 和 FAM（分别使用荧光素 dT 亚磷酰胺和 FAM CPG）。

TAMRA 5′ 标记的寡核苷酸通常用于定量 PCR 和片段分析（例如，用于微卫星标记分析），因为可用的设备经常具有 TAMRA 检测通道。

TAMRA 染料在存在铵和空间位阻伯胺时不稳定，因此强烈建议遵循特定条件进行标记的寡核苷酸脱保护。

Usage

Coupling: 7.5 min.

Deprotection: tret-buthylamine : methanol : water 1 : 1 : 3 (v/v/v) («TAMRA cocktail») for 6 hours at 60 °C, then cool down to room temperature.

Due to complete and irreversible degradation of the TAMRA dye, do NOT use aqueous ammonium and AMA for deprotecting a modified oligonucleotide from the solid-phase support.

耦合：7.5 分钟。

脱保护：三丁胺：甲醇：水 1 : 1 : 3 (v/v/v)（《TAMRA 鸡尾酒》）在 60°C 下 6 小时，然后冷却至室温。

由于 TAMRA 染料会完全且不可逆地降解，因此请勿使用铵水溶液和 AMA 将修饰的寡核苷酸从固相载体上脱去保护。

SIMA (дихлордифенилфлуоресцеин) — ксантеновый краситель со спектральными свойствами, аналогичными HEX, однако с более высоким квантовым выходом. SIMA также обладает повышенной стабильностью во время деблокирования в основных условиях, поэтому деблокирование может проводиться с использованием водного раствора аммиака при повышенных температурах либо с помощью AMA (смесь 1:1, концентрированный водный аммиак / 40% водный метиламин) при комнатной температуре в течение 2 часов или 65°C в течение 10 минут. При деблокировании водным раствором аммиака при 55°C в течение ночи SIMA, связанный с олигонуклеотидом, не деградирует, в том время как для HEX наблюдается деградация флуорофора как минимум на 10%.

SIMA фосфорамидит используется в олигонуклеотидном синтезе для для получения флуоресцентно-меченых праймеров и гибридизационных зондов для количественной ПЦР.

R6G phosphoramidite for oligonucleotide synthesis, pure 6-isomer.

R6G (rhodamine 6G) is a xanthene dye of the rhodamine family with high fluorescence quantum yield and high molar extinction coefficient. Relative to those of fluorescein, the absorption (518 nm) and emission (542 nm) maxima of 6-R6G are shifted into the long-wave region.

R6G can be used as a FRET acceptor in DNA-sequencing and in short tandem repeat (STR) analysis. The dye is commonly used for producing TaqMan probes for quantitative PCR. In comparison with HEX and JOE dyes, R6G in combination with BHQ1 quencher has stronger quenching in molecular beacon probes, significantly reducing background fluorescence in PCR.

用于寡核苷酸合成的 R6G 亚磷酰胺，纯 6 异构体。

R6G（罗丹明 6G）是罗丹明家族的一种呫吨染料，具有高荧光量子产率和高摩尔消光系数。 相对于荧光素，6-R6G 的最大吸收 (518 nm) 和发射 (542 nm) 转移到长波区域。

R6G 可用作 DNA 测序和短串联重复 (STR) 分析中的 FRET 受体。 该染料通常用于生产用于定量 PCR 的 TaqMan 探针。 与 HEX 和 JOE 染料相比，R6G 与 BHQ1 猝灭剂组合在分子信标探针中具有更强的猝灭作用，显着降低了 PCR 中的背景荧光。

Pyrene is a polycyclic aromatic hydrocarbon that is well-known for its ability to intercalate into DNA. Pyrene features intense blue fluorescence. Its parameters depend strongly on the fluorophore microenvironment. Therefore, fluorescence spectra of pyrene are used for the extraction of structural information about the site surrounding pyrene. Two pyrenes in close proximity usually form excimers easily detectable by excimer fluorescence. Pyrene can also be a FRET donor to other fluorophores such as perylene.

With this phosphoramidite, pyrene can be introduced into DNA by means of automated synthesis. This pyrene phosphoramidite contains hydrocarbon moiety rigidly attached to deoxyuridine. This reagent allows attaching pyrene fragment to 5′, internal, or 3′ position (using universal support).

This amidite requires no special handling, coupling, or deprotection conditions. Recommended diluent for it is acetonitrile.

Perylene is a bright and extremely photostable fluorescent polycyclic aromatic hydrocarbon (PAH) label with a quantum yield approaching quantitative. Due to the low lifetime of fluorescence, this probe does not form excimers.

With this phosphoramidite, perylene can be introduced into DNA by automated oligonucleotide synthesis. Perylene is attached to the 5′ position of deoxyuridine (dU) through a triple bond and the fluorophore is electronically coupled to the deoxyuridine base. This coupling of dU and perylene makes the fluorescence sensitive to the base pairing of the dU portion of the molecule, allowing the discrimination between perfect and one base mismatched targets.

This amidite requires no special handling, coupling, or deprotection conditions. Recommended diluent is acetonitrile.

Long trebler phosphoramidite is a branching reagent for oligonucleotide synthesis allowing to synthesize branched DNA structures using a standard DNA synthesizer.

长高音亚磷酰胺是一种用于寡核苷酸合成的支化试剂，允许使用标准 DNA 合成仪合成支化的 DNA 结构。

Long trebler phosphoramidite

After the condensation of the trebler, three DNA branches begin to grow simultaneously with each step of the synthesis. Deblock of this construct gives rise to DNA containing a branching point. One arm (stem) is attached to the branch point with its 5′-end, and other arms (branches) are attached with their 3′-ends. Reverse amidites can be used to prepare constructs with different branch orientations. Repetitive condensations of trebler results in formation of DNA dendrimers.

Trebler amidite can be used to attach several modifier amidites to the 5′-end of an oligonucleotide – for example, three biotin residues can be attached at once.

This amidite does not require any special handling. Recommended coupling time is 5 minutes. No changes to deblock conditions are required.

Trebler 亚酰胺可用于将几个修饰亚酰胺连接到寡核苷酸的 5′ 端 – 例如，可以一次连接三个生物素残基。

这种亚酰胺不需要任何特殊处理。 推荐的耦合时间为 5 分钟。 不需要改变去块条件。

我们的目录还包含 JOE 亚磷酰胺，5 异构体。 我们比较了含有不同 JOE 异构体（5-JOE 和 6-JOE）的 qPCR 探针，并没有发现它们之间有任何显着差异。

Usage

Coupling: 6 minutes

Deprotection: standard conditions using ammonium hydroxide; deprotection time depends on oligonucleotide composition and nucleobase protecting groups (deprotection for 17 h at 55 °С removes all protecting groups from standard nucleobases). AMA (solution of 30% ammonium hydroxide/40% aqueous methylamine 1:1 v/v) can be used with ~5% of non-fluorescent side product forming. To avoid formation of the side product, start deprotection with ammonium hydroxide (30 min at room temperature), then add an equal volume of 40% aqueous methylamine and continue deprotection as required with AMA (e.g. 10 min at 65 °C).

耦合：6 分钟

脱保护：使用氢氧化铵的标准条件； 脱保护时间取决于寡核苷酸组成和核碱基保护基团（在 55°С 脱保护 17 小时会去除标准核碱基上的所有保护基团）。 AMA（30% 氢氧化铵/40% 甲胺水溶液 1:1 v/v 的溶液）可用于形成约 5% 的非荧光副产物。 为避免形成副产物，用氢氧化铵开始脱保护（室温下 30 分钟），然后加入等体积的 40% 甲胺水溶液，并根据需要使用 AMA 继续脱保护（例如，在 65°C 下 10 分钟）。

HEX phosphoramidite for oligonucleotide synthesis, pure 6-isomer.

HEX (hexachlorofluorescein) is a fluorescein derivative with emission in the yellow spectrum range (absorption maximum at 533 nm, emission maximum at 549 nm).

HEX phosphoramidite is used for synthesis of fluorescent-labeled primers and hybridization probes such as TaqMan, Molecular Beacon, and Scorpion for qPCR. HEX is most effectively quenched by non-fluorescent DusQ1 dark quencher because of significant overlapping of their spectra (convenient for use with DusQ1 CPG 500 solid support with a pore size of 500 Å). Many automated sequencers based on capillary gel electrophoresis have a detection channel for HEX. Therefore, this phosphoramidite is commonly used for synthesis of 5’-labeled oligonucleotides for fragment analysis, particularly for microsatellite analysis, when microsatellite loci are amplified using a fluorescent-labeled forward primer and a non-labeled reverse primer.

用于寡核苷酸合成的 HEX 亚磷酰胺，纯 6 异构体。

HEX（六氯荧光素）是一种荧光素衍生物，在黄色光谱范围内发射（最大吸收在 533 nm，最大发射在 549 nm）。

HEX 亚磷酰胺用于合成荧光标记的引物和杂交探针，例如用于 qPCR 的 TaqMan、Molecular Beacon 和 Scorpion。 HEX 最有效地被非荧光 DusQ1 暗猝灭剂猝灭，因为它们的光谱有显着重叠（便于与孔径为 500 Å 的 DusQ1 CPG 500 固体支持物一起使用）。 许多基于毛细管凝胶电泳的自动测序仪都有一个 HEX 检测通道。 因此，当使用荧光标记的正向引物和未标记的反向引物扩增微卫星基因座时，这种亚磷酰胺通常用于合成 5′ 标记的寡核苷酸以进行片段分析，特别是用于微卫星分析。

Usage

Coupling: 3 min.

Deprotection: standard conditions using 25% ammonium; deprotection time depends on oligonucleotide composition and nucleobase protecting groups (deprotection for 17 h at 55 °С removes all protecting groups from standard nucleobases). AMA (solution of concentrated aqueous ammonium/40% aqueous methylamine 1:1 v/v) can be used with ~5% of non-fluorescent side product forming. To avoid formation of the side product, start deprotection with ammonium hydroxide (30 min at room temperature), then add an equal volume of 40% aqueous methylamine and continue deprotection as required with AMA (e.g. 10 min at 65 °C).

耦合：3 分钟。

脱保护：使用 25% 铵的标准条件； 脱保护时间取决于寡核苷酸组成和核碱基保护基团（在 55°C 下脱保护 17 小时会去除标准核碱基上的所有保护基团）。 AMA（浓铵水溶液/40% 甲胺水溶液 1:1 v/v）可用于形成约 5% 的非荧光副产物。 为避免形成副产物，用氢氧化铵开始脱保护（室温下 30 分钟），然后加入等体积的 40% 甲胺水溶液，并根据需要使用 AMA 继续脱保护（例如，在 65°C 下 10 分钟）。

This phosphoramidite allows fluorescein (FAM) to be introduced into any position in the oligonucleotide sequence during synthesis by the phosphoramidite method (in the middle of the chain, at the 5’- and 3’-terminus). The reagent is a conjugate of deoxythymidine phosphoramidite and 6-isomer of FAM. Modification is performed during oligonucleotide synthesis by substituting standard dT phosphoramidite with fluorescein-dT phosphoramidite. This modification does not affect exonuclease or polymerase activity.

For modification with fluorescein at the 5’-terminus use FAM phosphoramidite, 6-isomer.

Aminolink phosphoramidite for oligonucleotide synthesis. DMS(O)MT is a special protective group similar to traditional MMT, but designed as an improved alternative to it. DMS(O)MT aminolink is fully compatible with standard coupling, deblock, and purification protocols. However, DMS(O)MT group is much better suited for DMT-on and cartridge purification of amino-oligonucleotides because of higher stability, and better oligonucleotide recovery. Oligonucleotides containing DMS(O)MT are more stable in solution than MMT analogs.

In case of cartridge purification, DMS(O)MT protection allows for 2-3 fold increase of oligonucleotide yield, making this reagent a unique solution for high-throughput manufacturing of amino-oligonucleotides.

Cyanine5.5 is a fluorophore with the emission in far red range of the spectrum. This dye is useful for multiplex qPCR. Commercial six-channel qPCR instruments often have a channel for Cyanine5.5.

This phosphoramidite can be used for the synthesis of 5′-labeled oligonucleotides by direct labeling in oligonucleotide synthesizer.

The structure of phosphoramidite functional group that is attached to a secondary carbon atom provides extra stability against Arbuzov rearrangement. This helps maintaining coupling performance over a longer storage time in oligonucleotide synthesizer, compared to phosphoramidites derived of primary alcohols.

This reagent is designed for the synthesis of oligonucleotides bearing triple bond (alkyne) in the middle of the chain. Alkyne is attached to deoxyuridine fragment, and it does not interfere with the hybridization to the complementary strand. This allows to prepare modified oligonucleotide probes bearing fluorescent dyes, quenchers, and other fragments attached to the middle of the chain, by virtue of copper catalyzed Click chemistry reaction with various azides.

This phosphoramidite is solid, so it is easy to dispense and handle. It is compatible with the standard deblocking conditions.

该试剂设计用于合成在链中间带有三键（炔烃）的寡核苷酸。 炔烃与脱氧尿苷片段相连，不会干扰与互补链的杂交。 这允许通过铜催化的与各种叠氮化物的点击化学反应制备带有荧光染料、猝灭剂和其他连接到链中间的片段的修饰寡核苷酸探针。
这种亚磷酰胺是固体，因此易于分配和处理。 它与标准解块条件兼容。

Phosphoramidite for the synthesis of oligonucleotides with 5′-terminal alkyne for Click Chemistry.

This alkyne amidite has several advantages over 5’-hexynyl phosphoramidite, 5′-butynyl-CEP, and other 5′-terminal alkyne phosphoramidites. First, it is solid compound which is easier to handle and dispense. And due to its structure, it is also more stable in solution, and has longer shelf life

Diluent for this phosphoramidite is acetonitrile, 5 min coupling time is recommended. Because this amidite does not contain 5′-terminal DMT group, no 5′-deprotection needed. Oligonucleotides should be deblocked under standard conditions, and purified by PAGE, or ion exchange HPLC.

Oligonucleotides with this modification are ideal for the use in Click Chemistry (see our recommended protocol).

亚磷酰胺用于合成具有 5′-末端炔烃的寡核苷酸，用于 Click Chemistry。

与 5′-己炔基亚磷酰胺、5′-丁炔基-CEP 和其他 5′-末端炔基亚磷酰胺相比，这种炔基亚磷酰胺具有多个优点。 首先，它是更易于处理和分配的固体化合物。 并且由于其结构，在溶液中也更稳定，保质期更长

该亚磷酰胺的稀释剂是乙腈，建议偶联时间为 5 分钟。 因为这种亚酰胺不含 5′-末端 DMT 基团，所以不需要 5′-去保护。 寡核苷酸应在标准条件下解封，并通过 PAGE 或离子交换 HPLC 纯化。

具有这种修饰的寡核苷酸非常适合用于 Click Chemistry（请参阅我们推荐的方案）。
