Anti-CD59 / Complement Regulatory Protein / Protectin, clone 193-27

Formulation: Purified Ab WITHOUT BSA at 1.0mg/ml. Cellular Localization: Cell membrane, Secreted. Positive Control: Jurkat or Raji cells. Human lymphocytes. Human lymph node and tonsil. Chromosome Location: 11p13. Protein Function: Potent inhibitor of the complement membrane attack complex (MAC) action, which protects human cells from damage during complement activation (PubMed:11882685, PubMed:1698710, PubMed:2475111, PubMed:2475570, PubMed:2606909, PubMed:9053451). Acts by binding to the beta-haipins of C8 (C8A and C8B) components of the assembling MAC, forming an intermolecular beta-sheet that prevents incorporation of the multiple copies of C9 required for complete formation of the osmolytic pore (PubMed:11882685, PubMed:1698710, PubMed:36797260) , The soluble form from urine retains its specific complement binding activity, but exhibits greatly reduced ability to inhibit complement membrane attack complex (MAC) assembly on cell membranes [The Uniprot Consortium]
