H2N-PEG-SH (MW 1000)

H2N-PEG-SH (MW 1000) (Amine-PEG-Thiol (MW 1000) ) is a linear heterobifunctional polyethylene glycol derivative featuring both thiol and amine groups. This compound serves as a crucial crosslinking or bioconjugation agent with a PEG chain. The thiol or ?SH, also known as a mercapto group, selectively reacts with maleimide, OPSS, vinyl sulfone, and surfaces of transition metals, such as gold and silver.
