Description

General description

Atto 488 NHS ester is a hydrophilic fluorescent label with high water solubility. The fluorescence activity is excited efficiently at the 480-515nm range. A suitable excitation source for Atto 488 is the 488 nm line of the Argon-Ion laser.

Application

Atto 488 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 488 NHS ester are:

• Strong Absorption.
• High Fluorescence quantum yield.
• High Photostability.
• Excellent water solubility.
