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)。

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。

Usage:

Coupling: 10 minutes.

Deprotection: solution of tert-Butylamine in water (1:3 v/v) overnight at 55°С.

Aqueous ammonia and AMA (solution of 30% ammonium hydroxide/40% aqueous methylamine 1:1 v/v) must NOT be used for deprotection of the modified oligonucleotide from the solid-phase support because of complete and irreversible R6G degradation.

耦合:10 分钟。

脱保护:叔丁胺水溶液 (1:3 v/v) 在 55°С 下过夜。

由于 R6G 完全且不可逆地降解,因此不得使用氨水和 AMA(30% 氢氧化铵/40% 甲胺水溶液 1:1 v/v)将修饰的寡核苷酸从固相载体上脱保护。

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.

Perylene 是一种明亮且极耐光的荧光多环芳烃 (PAH) 标记,其量子产率接近定量。 由于荧光的低寿命,该探针不会形成准分子。

使用这种亚磷酰胺,可以通过自动寡核苷酸合成将苝引入 DNA。 苝通过三键连接到脱氧尿苷 (dU) 的 5′ 位置,并且荧光团与脱氧尿苷碱基电子耦合。 dU 和苝的这种偶联使荧光对分子的 dU 部分的碱基配对敏感,从而可以区分完美和一个碱基错配的靶标。

这种亚酰胺不需要特殊的处理、偶联或脱保护条件。 推荐的稀释剂是乙腈。

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)。

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.

Chemical phosphorylation reagent for oligonucleotide synthesis

Chemical phosphorylation reagent for oligonucleotide synthesis,用于合成 5′-磷酸化寡核苷酸的化学磷酸化试剂。 该试剂的结构中含有一个 DMT 基团,可以在 C18 小柱上或通过反相色谱法纯化寡核苷酸。 要产生 5′-磷酸化寡核苷酸,请去除 DMT 基团,然后用稀释的铵溶液 (0.1 M) 去保护磷酸基团。 即使在温和的碱性条件下,磷酸基团的脱保护也能快速有效地进行,因此该试剂可用于 DMT-Off 合成,例如 RNA 合成,或用于需要温和脱保护条件的染料亚磷酰胺。

Chemical phosphorylation reagent for the synthesis of 5’-phosphorylated oligonucleotides. The reagent contains a DMT group in its structure, which allows oligonucleotide purification on C18-cartridges or by reversed-phase chromatography. To yield 5’-phosphorylated oligonucleotide, remove DMT group and then deprotect the phosphate group with diluted ammonium solution (0.1 M). Deprotection of the phosphate group is rapid and efficient even under mild basic conditions, so this reagent can be used for DMT-Off synthesis, for example for RNA synthesis, or with dye phosphoramidites that require mild deprotection conditions.
