NH2-PEG200-SH

NH2-PEG200-SH/Amine-PEG200-SH/Amine-PEG200-Thiol/NH2-PEG200-Thiol is a multifunctional polyethylene glycol research reagent. PEG chains themselves can enhance molecular water solubility, reduce non-specific adsorption, and alleviate steric hindrance of functional groups at both ends; Amino groups can undergo mild reactions with carboxyl groups, isocyanates, active esters, etc. Thiol groups can react with maleimide, gold surfaces, disulfide bonds, etc. The two functional groups can react separately at physiological pH without interfering with each other, achieving bidirectional coupling.
