Lumiprobe 磺酸基CY3.5 NHS酯 sulfo-Cyanine3.5 NHS ester

上海金畔生物代理Lumiprobe品牌产品，欢迎新老客户访问Lumiprobe官网或者咨询我们获取更多相关产品信息。

Cyanine3.5 is a fluorescent dye with absorption and emission intermediate between Cyanine3 and Cyanine5. Sulfonated version contains four sulfo groups which ensure high solubility and hydrophilicity of the fluorophore and labeled conjugates.

The NHS ester reactive group allows to label primary and secondary amine groups.

Lumiprobe TAMRA NHS ester, 5-isomer

上海金畔生物代理Lumiprobe品牌产品，欢迎新老客户访问Lumiprobe官网或者咨询我们获取更多相关产品信息。

TAMRA (tetramethylrhodamine) is a xanthene dye of rhodamine series. This fluorophore is being used for quite a long time for the preparation of dual labeled qPCR TaqMan oligonucleotide probes containing TAMRA and fluorescein (FAM).

Just like many other xanthene fluorophores, TAMRA is a available as two isomers (5- and 6-isomer) which have nearly identical optical properties. This product is an isomerically pure 5-TAMRA.

TAMRA NHS is an amine reactive reagent. It can be used for the labeling of proteins, peptides, and modified oligonucleotides containing amine groups.

Lumiprobe 水溶性CY5 NHS酯 Sulfo-Cyanine5 NHS ester

上海金畔生物代理Lumiprobe品牌产品，欢迎新老客户访问Lumiprobe官网或者咨询我们获取更多相关产品信息。

Water soluble 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^®, Alexa Fluor 647, DyLight 649 for all applications.

Lumiprobe 水溶性CY3 NHS酯 Sulfo-Cyanine3 NHS ester

上海金畔生物代理Lumiprobe品牌产品，欢迎新老客户访问Lumiprobe官网或者咨询我们获取更多相关产品信息。

Water soluble, amino-reactive sulfo-Cyanine3 NHS ester. Efficiently labels proteins and peptides in purely aqueous solution, without need for organic co-solvent. Ideal for proteins with low solubility, and proteins prone to denaturation.

This is sulfonated, hydrophilic and water-soluble dye. Non-sulfonated Cyanine3 NHS ester is also available.

This product is an analog of Cy3® NHS ester. Sulfo-Cyanine3 NHS ester replaces Cy3®, Alexa Fluor 546, and DyLight 549 for all applications.

Lumiprobe Pyrenebutyric acid NHS ester

上海金畔生物代理Lumiprobe品牌产品，欢迎新老客户访问Lumiprobe官网或者咨询我们获取更多相关产品信息。

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.

Lumiprobe BDP FL NHS ester CAS 146616-66-2

上海金畔生物代理Lumiprobe品牌产品，欢迎新老客户访问Lumiprobe官网或者咨询我们获取更多相关产品信息。

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, Alexa Fluor 488, DyLight 488, Cy2, and other 488 nm dyes.
