BP Fluor 488 NHS ester is a powerful labeling dye. It will react with the amine group in antibody, proteins, peptides, amino-modified oligos, and other target molecules. The dye has an excitation peak at 499 nm and an emission peak at 520 nm. The conjugates are widely used in microscopy, flow cytometry, and other applications. BP Fluor 488 is a pure 5- sulfonated rhodamine molecule and it eliminates the lot-to-lot variation caused by two isomers ratio differences.
