Thiol-PEG-Amine (HS-PEG-NH2, SH-PEG-NH2) is a linear heterobifunctional PEGylation reagent with a thiol and an amine moiety. It can be used to modify proteins, peptides and other materials or small molecules. The amino group (NH2) can easily form stable amide bonds with carboxyl groups, as well as with reactive esters (-NHS) at pH 7-8.5. Thiol groups (SH) and maleimide can easily form stable thioether bonds at PH6.5-7.5. Thiol (SH) groups have high affinity for gold surfaces and are widely used for gold nanoparticles or gold film modification. PEGylation improves solubility and stability and reduces the immunogenicity of proteins and peptides. It can also inhibit the non-specific binding of charged molecules on the modified surface.
