6-Maleimidocaproic acid PFP ester contains a maleimide and PFP ester end group. Maleimides react with thiol groups within the pH range of 6.5 to 7.5 and form stable thioether bonds. PFP is an activated ester which can readily react with amine-bearing molecules to form stable amide bonds. The PFP ester is less prone to hydrolysis than NHS ester.
