Special InstructionsWe recommend resuspending the lyophilized antibody with sterile PBS, pH 7.4, or sterile 20 mM Tris-saline (20 mM Tris containing 0.15 M NaCl), pH 7.4, to yield a final concentration of 100 µg/ml; product will be more stable if 0.1% sodium azide is included (do not add sodium azide if antibody is to be used with viable cells). Lyophilized antibodies should be resuspended at 4°C with occasional gentle mixing for at least 2 h. Following reconstitution, refrigerate (4°C) for short-term storage or aliquot and freeze (-20°C) for long-term storage. Avoid freeze/thaw cycles of solutions.

DescriptionPurified mouse monoclonal antibody generated by immunizing Balb/c mice with the specified immunogen and fusing splenocytes with S194/5XXO.BU.1 mouse myeloma cells (see application references). Recognizes the ~90 kDa (monomeric) and the ~180 kDa (dimeric) transferrin receptor protein.
BackgroundTransferrin is the major iron binding protein in human plasma and is bound by a specific cell surface receptor during transport of iron into various tissues. The human transferrin receptor was originally isolated from placenta and shown to contain a subunit with an apparent molecular weight of 90,000. Further structural characterization of the receptor revealed that it resides in the plasma membrane as a 180,000 dimer, has a pI of 5.2, is phosphorylated predominantly on serine residues and contains both complex and high mannose oligosaccharide chains. Transferrin receptor is considered to be a marker for proliferating cells and its levels can be drastically reduced by agents which cause differentiation of undifferentiated cells such as HL-60 cells. Since many of the enzymes of metabolically active, proliferating cells require iron to catalyze redox reactions it is not surprising that the transferrin receptor would be a marker of proliferation. Further support for this hypothesis has been obtained by using antibodies to block transferrin binding and cause the accumulation of cells in S-phase, presumably due to interference with normal iron uptake and energy metabolism. Thus, monoclonal antibodies recognizing the transferrin receptor are not only valuable tools for studying iron metabolism, but may also be useful for monitoring and possible therapy of diseases involving highly proliferative cells.
