产品介绍：

N-hydroxylsuccinimide (NHS) functionalized polyethylene glycol valeric acid (PEG-SVA) is an amino (-NH₂) reactive PEG derivative that can be used to modify protein, peptide or any other surfaces with available amino groups. NHS esters react with primary amine groups at pH 7~8.5 to form stable amide bonds.Compared to other PEG NHS ester derivatives, our succinimidyl valeric acid PEG (mPEG-SVA) offers superior reactivity yet higher stability in aqueous solution. NHS esters react with deprotonated primary amines, therefore, the reaction requires neutral to basic pH values to proceed. Primary amines react with NHS esters by nucleophilic attack and NHS is released as a byproduct. Hydrolysis of the NHS-ester competes with the reaction in aqueous solution and increases with increasing pH.
