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.
