| Hazard Information | Back Directory | [Description]
Cyanine3B NHS ester is a reactive dye for the specific labeling of amino-groups in biomolecules — antibodies, peptides, or oligonucleotides. Cyanine3B is an improved version of yellow Cyanine3 dye with significantly increased fluorescence quantum yield and photostability. | [Uses]
Cy3B NHS ester is a fluorescent dye compound that is commonly used in biomarking and fluorescent labeling experiments, especially for labeling biomolecules containing amino functional groups (amine groups), such as proteins, antibodies or peptides. | [Definition]
ChEBI: Cy3B dye NHS ester is a fluorescent dye with a maximum emission wavelength of 572 nm, derived from a heteroheptacyclic ring system. It has a role as a fluorochrome. It is an iminium betaine, an organic heteroheptacyclic compound and a cyanine dye. | [Abs/Em Maxima]
