maleimide peg4 nhs

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-PEG4-NHS ester is a noncleavable ADC linker with a Maleimide group, a 4-unit PEG, and an NHS ester.

Mal-PEG4-amine 是一种包含马来酰亚胺基团和胺基团的 PEG 连接体。亲水性 PEG 间隔物提高了其在水性介质中的溶解性。胺基团能够与羧酸、活化 NHS 酯及羰基（酮、醛）等化合物发生反应。马来酰亚胺基团则与硫醇基团反应形成共价键，用于结合含硫醇的生物分子。
