uniprot entry name :

A2MG_HUMAN

reactivity :

Human

specificity :

This assay has high sensitivity and excellent specificity for detection of PRE-?2 MG. No significant cross-reactivity or interference between PRE-?2 MG and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between PRE-?2 MG and all the analogues, therefore, cross reaction may still exist in some cases.

storage stability :

Store all reagents at 2-8 degree C.

other info1 :

Samples: Serum, plasma, Cell Culture Supernatants, body fluid and tissue homogenate. Assay Type: Competitive. Sensitivity: 1.0 umol/L.

other info2 :

Intended Uses: This PRE-?2 MG ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human PRE-?2 MG. This ELISA kit for research use only, not for therapeutic or diagnostic applications!

products description :

Principle of the assay: PRE-?2 MG ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-PRE-?2 MG antibody and an PRE-?2 MG-HRP conjugate. The assay sample and buffer are incubated together with PRE-?2 MG-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the PRE-?2 MG concentration since PRE-?2 MG from samples and PRE-?2 MG-HRP conjugate compete for the anti-PRE-?2 MG antibody binding site. Since the number of sites is limited, as more sites are occupied by PRE-?2 MG from the sample, fewer sites are left to bind PRE-?2 MG-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The PRE-?2 MG concentration in each sample is interpolated from this standard curve.

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; 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; 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
