The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use 5µl for 106 cells. ab91356-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
Use at an assay dependent concentration.
功能This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade.
组织特异性Expressed on the plasma membranes of all cell types that are in intimate contact with plasma complement proteins. It is also found on the surfaces of epithelial cells lining extracellular compartments, and variants of the molecule are present in body fluids and in extracellular matrix.
序列相似性Belongs to the receptors of complement activation (RCA) family. Contains 4 Sushi (CCP/SCR) domains.
结构域The first Sushi domain (SCR1) is not necessary for function. SCR2 and SCR4 provide the proper conformation for the active site on SCR3.
翻译后修饰The Ser/Thr-rich domain is heavily O-glycosylated.
Overlay histogram showing peripheral blood lymphocytes stained with ab25634 (red line). The cells incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab25634, 0.5 µg/1x106 cells) for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 FITC (2 µg/1x106 cells ) for 30 min at 22°C. Acquisition of >5,000 events was performed.
