| | 4-arm-PEG-SH Usage And Synthesis |
| Uses | 4-arm-PEG-SH can specifically couple with molecules containing functional groups such as maleimide and iodoacetamide through the thiol group, and can be used for the modification and labeling of biomolecules. In drug delivery systems, it can be used as a linker to connect drug molecules with target molecules or carriers to achieve targeted drug delivery. | | Chemical Properties | Tetra-arm polyethylene glycol mercaptans are usually white or yellowish solid or liquid viscous depending on the molecular weight. The sulfhydryl group (SH) in its structure is a highly reactive functional group that can react with a wide range of chemicals, such as thiol-thiol coupling reactions and thiol-maleimide addition reactions. |
