Citraconic anhydride

Citraconic anhydride (Methylmaleic anhydride) is a derivative of maleic anhydride and novel antigen retrieval solution. Citraconic anhydride reversibly blocks protein amino groups, stabilizing specific enzymes and improving their catalytic performance. Citraconic anhydride reacts with free amino groups on proteins (especially lysine residues), converting positively charged NH3+ into carboxyl groups, thereby disrupting methylene bridge crosslinks caused by Formaldehyde during antigen retrieval. Citraconic anhydride functionalizes Isotactic polypropylene. Citraconic anhydride precisely responds to pH changes to achieve reversible modification. Citraconic anhydride is irritating to skin and eyes[1][2][3][4][5].
