It is sh-peg-nh2 mercapto polyethylene glycol amino group of Huasheng, wherein the amino group modifies the molecule with carboxyl group (catalyst is added in the reaction) or active ester group. Thiol modified gold nanoparticles can react with maleimide.

Hs-peg-nh2 is a linear heterobifunctional PEGylation reagent containing thiols and amines. It is a useful crosslinking or biological binding agent with PEG spacer. Sulfhydryl or amino groups selectively react with maleimide, OPSS, vinyl sulfone and transition metal surfaces (including gold, silver, etc.).

Weihua bio sh-peg-nh2 mercapto polyethylene glycol amino has a wide range of applications, mainly including:

1. Modification of protein drugs; 2. Modification of peptide compounds; 3. Modification of liposomes; 4. Organic small molecule drug modification; 5. PEG modified affinity ligands and cofactors; 6. PEG modified saccharides; 7. Oligonucleotide PEGylation; 8. PEGylation of biomaterials.
