Anti-Alpha-2-Macroglobulin / A2M, clone A2M/6556

Formulation: Purified Ab WITHOUT BSA and Azide at 1.0mg/ml. Cellular Localization: Secreted in plasma. Positive Control: Human liver or placenta tissues. Chromosome Location: 12p13.31. Protein Function: Is able to inhibit all four classes of proteinases by a unique 'trapping' mechanism. This protein has a peptide stretch, called the 'bait region' which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region, a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase [The Uniprot Consortium]
