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

For research use only, not for diagnostic or therapeutic use. The 143-30 antibody has been reported for use in flow cytometric analysis.

Applications Tested

The 143-30 antibody has been tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at less than or equal to 1 μg per 100 μl blood (or per 1 million cells in 100 μl total staining volume). It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
