Rhodamine 6G (R6G) is a xanthene dye of rhodamine series that has been used for the labeling of oligonucleotides and DNA for quite a long time. Just like other xanthenes, R6G comes as two isomers, 5- and 6-isomer. Even though their absorption and emission spectra are virtually indistinguishable, the isomers need to be separated to avoid separation of the labeled molecules during their purification, i.e. double HPLC peaks and double spots on electrophoresis.

This is an amine reactive NHS ester derived from a pure 5-isomer of R6G. Rhodamine 6G is very bright (even used as a quantum yield standard, yield 0.95). The dye is soluble in organic solvents, such as DMF, or DMSO. They can be used as co-solvents for the labeling reactions.

罗丹明 6G (R6G) 是罗丹明系列的呫吨染料，长期以来一直用于标记寡核苷酸和 DNA。就像其他呫吨一样，R6G 有两种异构体，5 和 6 异构体。尽管它们的吸收和发射光谱几乎无法区分，但需要分离异构体以避免在纯化过程中分离标记分子，即在电泳上出现双 HPLC 峰和双点。

这是一种胺反应性 NHS 酯，衍生自 R6G 的纯 5-异构体。罗丹明 6G 非常亮（即使用作量子产率标准，产率 0.95）。该染料可溶于有机溶剂，例如 DMF 或 DMSO。它们可用作标记反应的助溶剂。

Dibenzocyclooctyne (ADIBO, DBCO) is one of the most reactive cycloalkynes for strain promoted alkyne azide cycloaddition (spAAC) – a copper free Click chemistry reaction.

This is an amine-reactive NHS ester that provides easy attachment of the reactive moiety to almost any primary or secondary amine group, such as that of protein, peptide, or small molecule amine.

DBCO reacts instantly with azides. The rate of the reaction is much higher than that of copper-catalyzed reaction, and reactions with many other cyclooctynes. Unlike some other cyclooctynes, DBCO does not react with tetrazines – this allows to carry out orthogonal conjugation of azides with DBCO, and trans-cyclooctenes with tetrazines.

二苯并环辛炔 (ADIBO, DBCO) 是对应变促进炔烃叠氮化物环加成 (spAAC) 反应性最强的环炔烃之一 – 一种无铜点击化学反应。

DBCO 立即与叠氮化物发生反应。该反应的速率远高于铜催化的反应，以及与许多其他环辛炔的反应。与其他一些环辛炔不同，DBCO 不与四嗪反应 – 这允许叠氮化物与 DBCO 以及反式环辛烯与四嗪的正交共轭。

Sulfo-Cyanine5.5 NHS ester is an amine reactive activated ester of sulfonated far red Cyanine5.5 fluorophore, an analog of Cy5.5®. This is a reagent of choice for the labeling of antibodies, sensitive proteins, and others which require reactions in purely aqueous environment, or without any significant additions of organic co-solvents.

The dye is well suitable for non-invasive in vivo NIR imaging, and for the applications requiring low fluorescent background.

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.
