This antibody reacts with the Transferrin Receptor (TFR). Expressed on all dividing cells and can distinguish resting and activated T-cells. Immunoprecipitates a disulphide linked homodimer of 90 kDa by SDS PAGE. The antibody inhibits cell proliferation and the mixed lymphocyte response in vitro. Blocks the binding of R17 217.1.3. and R17 208.2 anti-TFR monoclonal antibodies (1,2).
Purification
Purified IgG prepared by affinity chromatography on Protein G from tissue culture supernatant
Immunogen
Mouse Concanavilin A activated spleen cells. Spleen cells from an immunised DA rat were fused with cells of the Y3/Ag1.2.3 rat myeloma cell line.
Flow Cytometry: Use 10 μL of 1/50-1/100 diluted antibody to label 10^6 cells in 100 μL. Immunoprecipitation. Immunohistochemistry on Frozen Sections. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Storage Comment
Store the antibody undiluted at 2-8 °C for one month or (in aliquots) at -20 °C for longer.
CD71 antigen expression is low on normal resting lymphocytes and is expressed on all cells upon activation. The transferrin receptor is essential for iron transport into proliferating cells, such as mitogen-activated and alloantigen-activated lymphoblasts. The transferrin receptor is also present on early erythroid cells but is lost as reticulocytes differentiate into mature erythrocytes.Synonyms: TfR1, Transferrin receptor protein 1, p90
