特點和優勢

SPDP-dPEG36-NHS ester is an amphiphilic, water-soluble PEGylation reagent that is designed to crosslink amines and free thiols. SPDP (also referred to as orthopyridyl disulfide, or OPSS) reacts with sulfhydryl groups to form disulfide bonds. The N-hydroxysuccinimidyl (NHS) ester reacts with free amines to form amide bonds. The single molecular weight, discrete chain length polyethylene glycol (dPEG) chain is 115 atoms (137.8 Å) long. SPDP-dPEG36-NHS ester is used like SPDP and its related hydrophobic products. However, the water-soluble dPEG product prevents hydrophobicity-triggered precipitation of compounds to which it is conjugated. SPDP-dPEG36-NHS ester is a monodisperse equivalent of the polymeric PEG1500.
