Samples: Immunoperoxidase Assay for Determination of Alpha 2-Macroglobulin in Human Samples. Assay Type: Sandwich

Intended Uses: The Alpha 2-Macroglobulin test kit is a highly sensitive two-site enzyme linked immunoassay (ELISA) for measuring Alpha 2-Macroglobulin in the serum and plasma of humans.

ELISA Kit

Principle of the Assay: The principle of the double antibody sandwich ELISA is represented in Figure 1. In this assay the Alpha 2-Macroglobulin present in samples reacts with the anti-Alpha 2-Macroglobulin antibodies which have been adsorbed to the surface of polystyrene microtitre wells. After the removal of unbound proteins by washing, anti-A2M antibodies conjugated with horseradish peroxidase (HRP), are added. These enzyme-labeled antibodies form complexes with the previously bound A2M. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3',5,5'-tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of A2M in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of A2M in the test sample. The quantity of A2M in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution. Background: Alpha 2-Macroglobulin (A2M) is a major protease inhibitor in serum and an acute phase protein which increases significantly in concentration in the human as a result of inflammation. The major pathophysiological role for human alpha 2-macroglobulin has yet to be conclusively defined. This kit is specific to the alpha 2- macroglobulin and will not cross react with the closely related alpha 1-macroglobulin.

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]

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; Inhibitor; Secreted. 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; regulation of small GTPase mediated signal transduction; extracellular matrix organization and biogenesis; platelet degranulation; small GTPase mediated signal transduction; stem cell differentiation; blood coagulation; blood coagulation, intrinsic pathway. Disease: Alzheimer Disease; Alpha-2-macroglobulin Deficiency
