Molecular definition of the M2 antigen has displayed it as no less than 3 separate target proteins. The M2 role is like the so-called E2 subunits (or dihydrolipoamide transferases) of different mitochondrial dehydrogenase complexes: *pyruvate dehydrogenase complex. *branched chain 2-oxo-acid dehydrogenase complex. *2-oxoglutarate dehydrogenase complex. Biochemically, these complexes catalyze the oxidative decarboxylation of various alpha-keto-acid substrates and systematically engage with a prosthetic lipoamide group; they are situated in the mitochondrial matrix in association with the inner membrane. The most well-known reactivity of AMA positive PBC sera is against PDC-E2. Some patients have AMA which reacts with PDC-E2 alone (95%), but most patients also show reactivity against OGDC-E2 (39-88%) and\/or BCOADC-E2 (53-55%). Actually, patients can be found with reactivity only against OGDC-E2 and\/or BCOADC-E2 and no PDC-E2 autoantibodies. These patients will be overlooked in assays based on natural source-derived, predominantly PDC-E2-containing M2 antigen preparations.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"bhp-desc\"\u003e\n\u003ch3 style=\"color:#1a5c58;margin:12px 0 4px\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:0.92em\"\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003ePurity\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eGreater than 75% as determined by SDS-PAGE.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003eFormulation\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eM2 is supplied in 16mM HEPES buffer pH-8.0, 400mM NaCl, and 20% glycerol.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:4px 8px;background:#e8f4f3;width:180px;font-weight:bold\"\u003eStorage\u003c\/th\u003e\n\u003ctd style=\"padding:4px 8px\"\u003eStore at 4°C if entire vial will be used within 2-4 weeks.
