CD55 (DAF) Antibody, anti-huma

Identification and enumeration of CD55 (DAF)+ cells by flow cytometryClone REAL510 is an antibody fragment derived from the full CD55 (DAF) antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAlease Complex to bind markers with high avidity. | Clone REAL510 recognizes the CD55 antigen, a 70 kDa glycosylphosphatidylinositol-anchored single chain glycoprotein, which is also known as complement decay-accelerating factor (DAF). CD55 is broadly distributed among hematopoietic and non-hematopoietic cells. It is expressed on the plasma membranes of all cell types that are in intimate contact with serum and on the surfaces of epithelial cells lining the extracellular compartments. Variants of the molecule are present in body fluids and in extracellular matrix. CD55 plays multiple physiologic roles including tissue protection from the cytotoxic complement injury, anti-inflammatory function owing to its anti-adherence properties which enhance transmigration of monocytes and macrophages and reduce tissue injury. CD55 plays an essential role during pregnancy and is involved in the protection of the semiallogeneic fetus and in preventing uncontrolled infiltration by white cells. It is exploited in multiple pathologic conditions by pathogens and viruses in chronic tissue infection processes. | The REAlease Kits consist of the respective fluorochrome-conjugated REAlease Complexes and the REAlease Support Kit for removal of the REAlease Complexes and optional relabeling with different fluorochrome-conjugated REAlease Complexes.
