AF488 is a fluorescent dye. AF488 is a fluorophore pH-insensitive over a broad pH range (from 4 to 10). It has an absorption maximum at 495 nm and an emission maximum at 519 nm in the green spectrum region. The dye is hydrophilic and can be used to introduce the fluorescent label into various molecules, including proteins and antibodies. Conjugates of molecules with AF488 have high brightness and photostability and are commonly used in flow cytometry and microscopy. This allows the detection of biological objects with high sensitivity at a longer imaging time.

AF488 azide interacts with alkynyl derivatives of biomolecules in Click Chemistry reactions either in the presence of copper (I) catalyst (with terminal alkynes) or without catalyst (with cyclooctynes), leading to the formation of stable adducts.

Cyanine 5 succinimidyl ester (SE), an equivalent of Cy5^® NHS ester, for the labeling of various amine-containing molecules in aqueous phase without use of any organic co-solvent. This product is therefore particularly useful for the labeling of proteins which denature in the presence of organic co-solvents, as well as for proteins with low solubility.

Sulfo-Cyanine 5 is an analog of Cy5^®, one of the most popular fluorophores which is compatible with various equipment such as plate readers, microscopes, and imagers.

This dye is highly hydrophilic and water-soluble. A non-sulfonated analog is also available.

Can be used as a replacement for Cy5^®, DyLight 649 for all applications.

Cy 5 琥珀酰亚胺酯 (SE)，相当于 Cy5® NHS 酯，用于在不使用任何有机助溶剂的情况下标记水相中的各种含胺分子。因此，该产品特别适用于标记在有机共溶剂存在下会变性的蛋白质，以及低溶解度的蛋白质。

Sulfo-Cyanine 5 是 Cy5® 的类似物，Cy5® 是最受欢迎的荧光团之一，与读板机、显微镜和成像仪等各种设备兼容。

这种染料是高度亲水和水溶性的。也可使用非磺化类似物。

可作为 Cy5®、DyLight 649 的替代品用于所有应用。

Pyrene is a polyaromatic hydrocarbon which exhibits fluorescence in blue range of the spectrum. When two pyrene residues are closely spaced, excimer fluorescence is observed at longer wavelength. Therefore, pyrene is useful as a proximity label.

Pyrene exhibits affinity to graphite, and can be used as an anchor group for graphite. This reagent can be conjugated with biomolecules for their subsequent immobilization on graphite surfaces.

This NHS ester allows to label biomolecules with amino groups, such as proteins, peptides, amino-DNA and other molecules.

Pyrene is also a FRET donor for perylene.

During the last years, Cyanine5 (an analog of Cy5^®) has become an incredibly popular label in life science research and diagnostics. The fluorophore has its emission maximum in the red region, where many CCD detectors exhibit maximum sensitivity, and biological objects show low background. The dye color is very intense, therefore quantities as small as 1 nmol can be detected in gel electrophoresis by naked eye.

This Cyanine5 NHS ester (analog to Cy5^® NHS ester) is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides. This dye requires a small amount of organic co-solvent (such as DMF or DMSO) to be used in labeling reactions (please see our recommended for more details). This reagent is ideal for very cost-efficient labeling of soluble proteins as well as all kinds of peptides and oligonucleotides. This reagent also works well in organic solvents for small molecule labeling. For more sophisticated targets such as easily degradable proteins, when the use of DMF or DMSO is undesirable, consider using water-soluble sulfo-Cyanine 5 NHS ester which does not require any co-solvent, and features very similar fluorescent properties.

Cyanine5 fluorophore is compatible with various instrumentation including many fluorescent microscopes, imagers, scanners, and fluorescence readers. A number of various Cyanine5 analogs exist – Cyanine5 NHS ester can replace activated esters of Cy5® and DyLight 649.

在过去的几年里，Cyanine5（Cy5® 的类似物）已成为生命科学研究和诊断领域非常受欢迎的标签。荧光团在红色区域具有最大发射，许多 CCD 检测器在该区域表现出最大灵敏度，而生物物体则表现出低背景。染料颜色非常强烈，因此在凝胶电泳中肉眼可以检测到小至 1 nmol 的量。

这种 Cyanine5 NHS 酯（类似于 Cy5® NHS 酯）是一种活性染料，用于标记肽、蛋白质和寡核苷酸中的氨基。这种染料需要少量有机助溶剂（如 DMF 或 DMSO）用于标记反应（请参阅我们推荐的方案了解更多详细信息）。该试剂非常适合用于标记可溶性蛋白质以及各种肽和寡核苷酸的极具成本效益的方法。该试剂在有机溶剂中也适用于小分子标记。对于更复杂的目标，例如易于降解的蛋白质，当不希望使用 DMF 或 DMSO 时，请考虑使用不需要任何助溶剂且具有非常相似荧光特性的水溶性磺基花青 5 NHS 酯。

Cyanine5 荧光团与各种仪器兼容，包括许多荧光显微镜、成像仪、扫描仪和荧光阅读器。存在许多不同的 Cyanine5 类似物 – Cyanine5 NHS 酯可以替代 Cy5® 和 DyLight 649 的活化酯。

BDP FL NHS ester is an advanced dye for 488 nm channel, a replacement for fluorescein, a molecule identical to BODIPY FL® NHS ester. An amino-reactive dye for the labeling of proteins and peptides.

While the absorbance and emission spectra of this molecule stay within FAM excitation and emission channels, this dye provides much better photostability, and outstanding brightness. The fluorescence spectrum of BODIPY-FL is narrower than that of FAM. This provides a better brightness for monochromator based instruments, when emission wavelength can be tuned to dye maximum.

The dye is neutral, possesses low molecular weight, and retains high quantum yield in conjugates.

The dye is a good replacement for fluorescein (FAM), BODIPY-FL, DyLight 488, Cy2, and other 488 nm dyes.

BDP FL NHS 酯是一种用于 488 nm 通道的高级染料，是荧光素的替代品，荧光素是一种与 BODIPY FL® NHS 酯相同的分子。一种用于标记蛋白质和肽的氨基活性染料。

该染料是中性的，具有低分子量，并在偶联物中保持高量子产率。

该染料是荧光素 (FAM)、BODIPY-FL、DyLight 488、Cy2 和其他 488 nm 染料的良好替代品。

BDP 576/589 (a BODIPY™ 576/589 analog) is a boron dipyrromethene dye. This hydrophobic dye has high quantum yield and long excited-state lifetime (about 5 nanoseconds). It can be used for measuring fluorescence lifetime and fluorescence polarization and in two-photon laser scanning microscopy.

This reagent is an activated N-hydroxysuccinimide ester of the dye with reactivity to primary and secondary amino groups.

BDP 576/589（BODIPY™ 576/589 类似物）是一种硼二吡咯亚甲基染料。这种疏水染料具有高量子产率和长激发态寿命（约 5 纳秒）。它可用于测量荧光寿命和荧光偏振以及双光子激光扫描显微镜。

该试剂是染料的活化 N-羟基琥珀酰亚胺酯，对伯氨基和仲氨基具有反应性。

BDP TR X NHS ester

BDP TR X NHS ester is a derivative of BDP TR containing a long linker based on aminohexanoic acid (C6). The dye has absorption and emission close to ROX. The NHS ester function can be used for the conjugation with proteins and peptides.
BDP TR X NHS 酯是 BDP TR 的衍生物，含有一个基于氨基己酸 (C6) 的长接头。该染料具有接近ROX的吸收和发射。 NHS 酯功能可用于与蛋白质和肽的结合。

Coumarin 343 X NHS ester

Coumarin 343 is a blue emitting dye that can serve as a FRET donor for fluorescein (FAM). This structure features a linker between Coumarin 343 fluorophore, and the functional group. It provides better solubility, and spatial separation between the dye, and the functional group.
香豆素 343 是一种蓝色发射染料，可用作荧光素 (FAM) 的 FRET 供体。这种结构的特点是香豆素 343 荧光团和官能团之间有一个接头。它提供了更好的溶解性，以及染料和官能团之间的空间分离。

FAM amine, 5-isomer

Amino derivative of fluorescein, pure 5-isomer. Contains a linker arm between the aliphatic amine group, and the fluorophore. Useful for the labeling via enzymatic transamination, for the reactions with electrophilic reagents, and for reductive amination.
