Thiol PEG (PEG-SH) linkers have reactive thiol moiety on one side of the linear peg chain.and with either a Methyl ether, Amine (NH2), Maleimide (Mal), Carboxylic Acid (COOH) group at the other end (such as mPEG-SH, SH-PEG-NH2, SH-PEG-COOH). The thiol functional group readily react with biomolecules with maleimide, halogen acetate, thiol, cysteine, and OPSS. It has also been widely used surface modification of gold, and silver, etc. Surface-grafted poly(ethylene glycol) (PEG) molecules are known to prevent protein adsorption to the surface.
Axispharm offers a range of high purity PEG-SH reagents with different linker lengths.Different kinds of PEG Reagents may be available by custom synthesis.fast shipping.
