Application

Atto fluorescent labels are designed for high sensitivity applications, including single molecule detection. Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation. Atto 495 maleimide is suitable for fluorescence labeling of thiol/SH containing molecules.
