5(6)-Carboxyfluorescein NHS Ester (mixed isomers, 5(6)-FAM-SE)

Overview
This product is a mixture of 5- and 6-isomers of carboxyfluorescein NHS ester, an amine-reactive fluorescent dye. NHS esters react with primary amines to form stable amide bonds, making this dye well suited for covalent labeling of biomolecules.

Applications

• Labeling of oligonucleotides for fluorescence detection or quantification

• Covalent labeling of peptides and proteins in biochemical assays

• Fluorescent tagging of biomolecules for imaging or tracking applications
