Description

General description

Atto 488 is a superior fluorescent label with high molecular absorption (90.000) and quantum yield (0.80) as well as sufficient stoke′s shift. It is optimized for excitation with argon laser, and is characterized by high photo stability.
The iodoacetamide derivative reacts, like the maleimide, with a sulfhydryl group forming a thioether bond. It is predominantly used for tagging cystein residues of proteins.
