Maleimide(Mal) PEG
Multi-Arm Maleimide PEG (MAL-PEG) derivatives are branched poly(ethylene glycol) structures characterized by a central core from which multiple PEG chains extend, each terminated with a reactive maleimide group. Their well-defined spatial structure allows efficient conjugation of small molecules, proteins, and nanocarriers, making them important building blocks in bioconjugation and biomaterial design.
Biopharma PEG offers 2-arm, 4-arm, and 8-arm maleimide PEGs, providing flexible options for thiol-reactive coupling and advanced applications in drug delivery, hydrogel formation, and nanotechnology.
