Clone Number: F4-29D9
Immunogen: human umbilical vein endothelial cells
Concentration: 100 ug/ml
Storage buffer: PBS with 0.02% sodium azide
Additional info: F4-29D9 reacts with CD55 or DAF (Decay Accelerating Factor). All leucocytes as well as human erythrocytes, fibroblasts, platelets, endothelial cells and neuroectodermal cells are positive for DAF. F4-29D9 also recognizes an antigen on spermatozoid cells. It is a glycosylphosphatidylinositol anchored (GPI-anchored) member of the membrane bound complement regulatory proteins that inhibit autologous complement cascade activation. CD55 also serves as receptor for CD97 and for echovirus and coxsackie B virus. DAF is deficient in both granulocytes and monocytes in patients with paroxysmal nocturnal haemoglobinuria.
