General description

Atto 532 NHS ester is a fluorescent dye related to the well-known laser dye, Rhodamine 6G. The fluorescence activity is excited efficiently at the 515-545nm range. A suitable excitation source for Atto 532 is the 532 nm output of the frequency-doubled Nd: YAG laser.

Application

Atto 532 NHS ester is highly suitable for single-molecule detection applications and high-resolution microscopy such as PALM, dSTORM, and STED. In addition, the dye is used in flow cytometry (FACS) and fluorescence in-situ hybridization (FISH) methods.

Features and Benefits

Characteristic features of the Atto 532 NHS ester are:
  • Strong Absorption.
  • High Fluorescence quantum yield.
  • High Photostability.
  • Excellent water solubility.
