Application

N-Maleoyl-β-alanine (3-maleimidopropanoic acid, N-(2-carboxyethyl)maleimide)) is the suitable reagent used in the following studies:
  • To decrease the biotin binding affinity of Avd(S16C) (avidin with a single point mutation S16C).
  • As a side chain reactive agent to modify tryptic peptides that result in mass shifts indicating the presence of cysteine residues.
  • To preblock Xenopus laevis oocytes for exposed cysteines used as an expression system in the study of conformational changes in cASIC1a Receptors.
It may be used in the following studies:
  • As a protective agent for keratin fiber in high temperature process.
  • As a non-cleavable maleimido moiety during the synthesis of tetrawalled molecular umbrella-octaarginine conjugates.
  • Synthesis of organotin carboxylates of N-Maleoyl-β-alanine.
  • To functionalize the gold surfaces to interact with cysteine-modified peptide.
  • Preparation of cross-linked dextran–poly(ethylene glycol) hydrogel substrate.
