ATTO 532 NHS ester

ATTO 532 is a rhodamine-based fluorescent labeling dye with high molecular high extinction coefficient and fluorescence quantum yield (0.90) as well as sufficient Stoke's shift (excitation maximum 532 nm, emission maximum 553 nm). The dye also has relatively good photostability. It is optimized for excitation with frequency doubled Nd:YAG-Laser. ATTO 532 NHS ester is used for labeling amino-containing molecules such as proteins, peptides and amino-modified oligonucleotides. Solvent: DMSO. Spectral properties: Excitation (nm): 532. Emission (nm): 552.
