Product Description
Maleimide capped 4-arm poly(lactide-co-glycolide) (4-arm PLGA-Maleimide, 4-arm PLGA-Mal) is a multiarm PLGA derivative with amine groups at each terminal of the four arms connected to one pentaerythritol core. The maleimide group selectively reacts with free thiol, SH, sulfhydryl, or mercapto group via Michael addition to form a stable carbon sulfur bond. 4-Arm PEG-MAL can be used for site specific protein and peptide modification. Otherwise noted, multiarm PLGA is composed of d,l-lactide and glycolide (50:50 ratio).
