A2M / Alpha-2-Macroglobulin

alpha-2-macroglobulin

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.

Gene Name: alpha-2-macroglobulin
Synonyms: A2M, CPAMD5, A2MD, FWP007, Alpha-2-M, Alpha-2-macroglobulin, S863-7
Target Sequences: NM_000014 NP_000005.2 P01023

A2M / Alpha-2-Macroglobulin Antibody - Western blot analysis of Alpha2-Macroglobulin antibody was performed by loading 5ul of Human Plasma and 5ul PageRuler Plus Prestained Protein Ladder onto a 4-20% Tris-Glycine polyacrylamide gel. Proteins were transferred to a nitrocellulose membrane using the G2 Fast Blotter and blocked with 5% milk in TBST for at least 1 hour at room temperature. Alpha 2 Macroglobulin was detected at ~180kD using an Alpha2-Macroglobulin monoclonal antibody at a concentration of 1 µg/mL in 5% milk in TBST overnight at 4C on a rocking platform, followed by an incubation with a goat anti-mouse IgG-HRP Superclonal secondary antibody at a dilution of 1:1000 for at least 1 hour. Chemiluminescent detection was performed using SuperSignal West Pico.
