I. [Product Description] 
WGA-PEG-SH is a thiol-functionalized organic intermediate based on the covalent coupling of wheat germ agglutinin (WGA) and polyethylene glycol (PEG). It combines biological recognition properties with chemical modification flexibility. This compound can be used as an efficient pharmaceutical intermediate or catalyst carrier, suitable for bioconjugation, surface modification of nanomaterials, and complex molecular assembly systems. Its PEG segment significantly enhances water solubility and stability.
