Crotonaldehyde Antibody: ATTO 488

Lipid peroxidation occurs when oxidizing agents attack carbon-carbon double bonds found in unsaturated lipids. In addition to membrane degradation, oxidation end-products have been found to damage cell viability through their mutagenic and toxic properties. These downstream functional consequences facilitate the development of disease and premature aging. Crotonaldehyde (CRA) is a carcinogenic, conjugated aldehyde produced endogenously via lipid peroxidation. It covalently modifies biomolecules, forming adducts with DNA and nucleophilic amino acid residues of proteins such as lysine (1).

Specific for Crotonaldehyde modified proteins. Does not cross-react with Acrolein, Hexanoyl Lysine, 4-Hydroxy-2-hexenal, 4-Hydroxy nonenal, Malondialdehyde, or Methylglyoxal modified proteins.

A 1:1000 dilution of SMC-534 was sufficient for detection of Crotonaldehyde-modified proteins in 1 µg of Crotonaldehyde-BSA conjugate by ECL immunoblot analysis using goat anti-mouse IgG:HRP as the secondary antibody.
