rat monoclonal IgG2a; CD47 Antibody (MIAP301) is an IgG2a rat monoclonal CD47 antibody that detects the immunoglobulin domain of CD47 of mouse and rat origin by WB, IP, IF and FCM. CD47 Antibody (MIAP301) is available as both conjugated and non-conjugated anti-CD47 antibody forms. CD47 is an integral membrane protein that plays a role in the regulation of cation fluxes across cell membranes. Specifically, CD47 is involved in the increase in intracellular calcium concentration that occurs upon cell adhesion to the extracellular matrix. It is also a receptor for the C-terminal cell binding domain of thrombospondin (SIRP). CD47 is absent from Rh-null erythrocytes, but does play a role in cell adhesion in non-erythroid cells and may prevent premature elimination of erythrocytes. It may also be involved in membrane permeability changes following viral infection. CD47 is expressed on hemopoietic cells, epithelial cells, endothelial cells and fibroblasts and is strongly expressed in brain and mesenchymal cells.
