I. [Product Description]
R8-PEG-BSA is a functionalized organic intermediate based on the covalent coupling of arginine octamer (R8) cell-penetrating peptide with polyethylene glycol (PEG) and bovine serum albumin (BSA), which combines high-efficiency membrane penetration and biocompatibility. As a pharmaceutical intermediate, it can achieve precise modification of molecular size and surface charge through the regulation of PEG molecular weight, and is suitable for bioconjugation reactions and nanoparticle carrier preparation. This compound can also be used as a catalyst carrier to optimize the mass transfer efficiency of complex reaction systems.

II. [Product Details]
