Mouse anti Human CD143 antibody, clone 2E2 recognizes human CD143, also know as angiotensin - converting enzyme (ACE). CD143 exists in two forms, a 170 kDa somatic form and a 90 kDa germinal form. The somatic form is expressed by endothelial cells (especially those of lung capillaries and arterioles), epithelial cells (especially in proximal renal tubules and small intestine), by some neuronal cells and variably by some macrophages and T lymphocytes. The germinal form is expressed by spermatozoa. Study of CD143 may be relevant to fertility (especially sperm-egg interactions), atherosclerosis and in drug targeting to the lung. This clone recognises denatured somatic form of ACE, binding to an epitope in the C domain, and has been reported to be active in western blotting (Balyasnikova et al. 2003).
