Synonyms: mPEG1000-SH
m-PEG1000-thiol (mPEG1000-SH) is a surface modifier that can modify DNA thiolation and is used in the synthesis of gold nanorods (AuNR). m-PEG1000-thiol can load thiolated DNA onto AuNR, form a covalent bond with the surface of gold nanoparticles through the thiol group, and stabilize the nanoparticles by the steric hindrance effect of the polyethylene glycol chain, preventing aggregation and enhancing its biocompatibility. m-PEG1000-thiol can also provide a platform for the subsequent coupling of biomolecules (such as DNA, antibodies) by replacing surfactants (such as CTAB) on the surface of nanoparticles, thereby exerting its activity in promoting the functionalization of nanomaterials [2].

DTME (dithio-bis-maleimidoethane) is a homobifunctional, maleimide crosslinker specifically designed for conjugation between sulfhydryl groups (-SH). DTME, whose molecular structure consists of two maleimide groups connected by an ethylene disulfide bridge, can specifically react with thiol - containing molecules (such as cysteine residues) to form stable covalent bonds. DTME allows crosslinks that can be cleaved with reducing agents such as DTT (HY-15917). DTME is commonly utilized to explore and characterize protein structure, particularly oligomerization, or protein interactions .
