α-Succinimidyl-ω-maleimidyl poly(ethylene glycol) is a heterobifunctional PEG reagent enabling site-specific bioconjugation. Synthesized via sequential activation of terminal hydroxyls, it links NHS esters with maleimides for thiol-reactive coupling. Molecular formula: CnH2nOn(CH2CH2O)mC6H4N(CO)C(O)N(CO)C5H3N; CAS: varies by chain length.
Store under inert atmosphere at -20°C to prevent hydrolysis. Avoid contact with skin and eyes due to potential sensitization. Use only in controlled laboratory settings; not approved for direct clinical administration without formulation.
