Analysis of HuProt(TM) microarray containing more than 19,000 full-length human proteins using A2M antibody. These results demonstrate the foremost specificity of the A2M/3623 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt(TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt(TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.

Alpha-2-Macroglobulin (A2M) is a homotetrameric serum protein consisting of four identical subunits that form dimers through disulfide bonds. Initially, it was characterized as a pan-proteinase inhibitor that was able to bait proteinases into cleaving specific peptide sequences on A2M. This interaction induces a conformational change, thus enabling it to trap the proteinase and further inhibit its activity. Subsequently, A2M has been shown to function as a carrier protein and regulator of cytokines during inflammation.

Application Notes

Optimal dilution of the A2M antibody should be determined by the researcher.


A portion of amino acids 604-748 from the human protein was used as the immunogen for the A2M antibody.


Store the A2M antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
