Stearic acid-PEG-Mal, MW 2,000 is a heterobifunctional polyPEG with 18-carbon aliphatic chain and maleimide. The polymer has stearic acid as the hydrophobic tail and PEG as the hydrophilic chain, therefore it forms micelles in water. Maleimide can react with thiol or cysteine to generate thiosuccinimide molecule which is commonly used for bioconjugation. Reagent grade, for research use only.
