4arm PEG Maleimide, MW 40K derivative is a thiol-reactive multi-arm PEG polymer. PEG hydrogels have a variety of applications in medical devices and regenerative medicine, especially for controlled release of drugs, 2D and 3D cell culture, and wound closure and healing. Maleimides react with thiols or sulfhydryl-containing molecules at pH 6.5 to 7.5 by forming stable thioether bonds. Hydrophilic PEG chains increase the water solubility of compounds in aqueous media.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
