Description: The 143-30 monoclonal antibody reacts with human CD55, the 64-73 kDa molecule also known as DAF (Decay-Accelerating Factor). CD55 is a GPI-anchored single chain glycoprotein expressed on all cells in contact with serum including all hematopoietic cells and vascular endothelium; a soluble form of CD55 is also present in plasma and body fluids. CD55 is thought to play a role in the protection of cells from the damage by autologous complement via prevention of the amplification steps of the complement cascade. Antibodies against CD55 are mitogenic in the presence of phorbol esters.
Applications Reported: The 143-30 antibody has been reported for use in flow cytometric analysis.
Applications Tested: This 143-30 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.5 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

CD55 (decay-accelerating factor, DAF) is a GPI-anchored membrane glycoprotein that protects autologous cells from classical and alternative pathway of complement cascade. Bidirectional interactions between CD55 and CD97 are involved in T cell regulation and CD55 can still regulate complement when bound to CD97. In tumours, besides protection agains complement, CD55 promotes neoangiogenesis, tumorigenesis, invasiveness and evasion of apoptosis.
