I. [Product Description]
Mal-PEG-SPDP (Maleimide-Polyethylene Glycol-3-(2-pyridyldithio)propionic acid N-hydroxysuccinimide ester) is a multifunctional organic intermediate. Through the specific reaction of the maleimide group with the thiol group and the reversible disulfide bond property of the SPDP group, it is widely used in the cross-linking and modification of biomolecules. Its polyethylene glycol (PEG) segment can significantly improve water solubility. As an efficient catalyst carrier and reaction medium, it has important value in the field of bioconjugation.
