products description :
A major serum protein found at concentrations of 240 mg per 100 ml in men and 290 mg per 100 ml in women. Multifunctional, it promotes growth of mammalian cells in culture, stimulates the regeneration of lymphocytes in irradiated mice, possesses a transport functions for zinc and is a proteinase inhibitor that controls the clotting and fibrinolytic system. Clinically levels are increased in liver cirrhosis, nephrotic syndrome, diabetes, and severe burn cases. Prepared from plasma shown to be non reactive for HbsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA approved tests. >95% pure by SDS-PAGE. Add deionized water to original volume, aliquot and freeze unused portion.

ncbi summary :
Alpha-2-macroglobulin is a protease inhibitor and cytokine transporter. It inhibits many proteases, including trypsin, thrombin and collagenase. A2M is implicated in Alzheimer disease (AD) due to its ability to mediate the clearance and degradation of A-beta, the major component of beta-amyloid deposits. [provided by RefSeq, Jul 2008]
uniprot summary :
A2M: 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. Belongs to the protease inhibitor I39 (alpha-2- macroglobulin) family. Protein type: Secreted, signal peptide; Secreted; Inhibitor. Chromosomal Location of Human Ortholog: 12p13.31. Cellular Component: extracellular region; cytosol. Molecular Function: serine-type endopeptidase inhibitor activity; protein binding; enzyme binding; protease binding; growth factor binding; interleukin-8 binding; interleukin-1 binding; calcium-dependent protein binding; tumor necrosis factor binding; receptor binding. Biological Process: negative regulation of complement activation, lectin pathway; extracellular matrix disassembly; platelet activation; extracellular matrix organization and biogenesis; regulation of small GTPase mediated signal transduction; platelet degranulation; small GTPase mediated signal transduction; stem cell differentiation; blood coagulation; blood coagulation, intrinsic pathway. Disease: Alzheimer Disease; Alpha-2-macroglobulin Deficiency
