Description

4-Arm PEG-Maleimide (4-Arm PEG-MAL, 4-arm Poly(ethylene glycol) maleimide) is a multiarmed PEG derivative with maleimide at each terminal of the four arms connected to one pentaerythritol core. Maleimide selectively reacts with free thiol, SH, sulfhydryl, or mercapto group via Michael addition to form a stable thioether bond. PEG-MAL useful for site specific protein and peptide modification. Hydroquinone MEHQ at ~ 200 ppm may be present as inhibitors to prevent self polymerization and partial crosslinking. MEHQ may be removed per customer request.
