I. [Product Description]
VA-PEG-SPDP is a multifunctional organic intermediate that achieves controllable cross-linking of biomolecules through the precise coupling of valeric acid, polyethylene glycol (PEG), and SPDP active groups. This compound combines the steric hindrance effect of the PEG chain and the directional thiol-reaction property of the SPDP group. It can serve as an efficient catalyst and a functional modification reagent, and is widely used in the fields of bioconjugation and material modification.
