Atto 488-NHS ester

BioChemika, ≥80% (coupling to amines), for fluorescence

Descriptions

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.
