amine peg thiol (mw 5000)

Amine-PEG-thiol (MW 5000) is a polyethylene glycol (PEG)-based PROTAC linker primarily used for the synthesis of PROTACs[1].

Mal-PEG-NH2 TFA (MW 5000) is a linear heterobifunctional PEG product that includes maleimide and ?NH2 groups. The maleimide group has the ability to react with thiol, SH, mercapto, or sulfhydryl groups, while the amine group can interact with carboxylic acids or activated NHS esters.

H2N-PEG-SH (MW 5000) is a linear heterobifunctional polyethylene glycol derivative containing both thiol and amine groups. H2N-PEG-SH (MW 10000) serves as a crucial crosslinking or bioconjugation agent featuring a PEG chain. The thiol group (?SH), or mercapto group, selectively reacts with maleimide, OPSS, vinyl sulfone, and transition metal surfaces (including gold and silver).

FMOC-NH-PEG-SH (MW 5000) (FMOC-NH-PEG-Thiol (MW 5000)) is a PEG derivative containing an Fmoc protecting group and a reactive thiol (-SH) functional group. The thiol group is highly active and can specifically react with various molecules to form stable covalent bonds. Fmoc serves as a common amino-protecting group, shielding the amine from unintended reactions until it is intentionally removed for specific coupling reactions.
