Stearic acid-PEG-Mal (MW 5000) is a pegylated lipid reagent consisting of a stearic acid hydrophobic tail attached to an average 5,000 Da polyethylene glycol chain terminated with a maleimide group. Supplied in reagent grade for research use, the material is designed for nanoparticle or micelle formulation and for covalent attachment to thiol-containing biomolecules via maleimide-thiol chemistry.

  • Maleimide terminal group for selective thiol conjugation.
  • PEG chain (~5,000 Da) provides steric stabilization and solubility.
  • Stearic acid tail promotes self-assembly into micelles or lipid nanoparticles.
  • Reagent grade formulation intended for research use only.
  • Stable when stored sealed at 4°C; in solvent store at -80°C for long term.
