H2N-PEG-SH (MW 10000)

H2N-PEG-SH (MW 10000) (Amine-PEG-Thiol (MW 10000) ) is a linear heterobifunctional polyethylene glycol derivative containing thiol and amine groups. This compound serves as a significant PEG-linked crosslinking or bioconjugation reagent. The thiol (?SH) or mercapto group selectively reacts with maleimide, OPSS, vinyl sulfone, and surfaces of transition metals, such as gold and silver.
