Maleimide-PEG4-NHS is a sulfhydryl and amine reactive heterofuncational PEG linker. The chemical bonds formed through Maleimide-PEG4-NHS linker are stable and are not cleavable. The NHS ester reacts with amino groups at pH 7-9 to form stable amide bond wh
Mal-Ph-CONH-PEG4-NHS ester, a non-cleavable four-unit polyethylene glycol (PEG) ADC linker, plays a crucial role in the synthesis of antibody-drug conjugates (ADCs).
