General Notes
Mouse anti Human CD71 (Soluble) antibody, clone 23D10 recognizes human soluble CD71 (also known as transferrin receptor, or TfR). CD71 is a homodimeric membrane protein, approximately 90 kDa in size. It is responsible for the uptake of iron into the cell, by binding to and internalising iron-bound transferrin (ferrotransferrin). After the iron is released into the cell, the apotransferrin is relocated to the cell surface and released into the circulation. When CD71 is cleaved at Arg-100, a soluble (or serum) form of the protein is released. The level of soluble CD71 is used to detect erythropoietin misuse by athletes. It is also used to diagnose iron deficiency anemia. Mouse anti Human CD71 (Soluble) antibody, clone 23D10 recognizes human soluble transferrin receptor and the complex between soluble transferrin receptor and transferrin.
