It recognizes a ~85-95kDa protein which is identified as cell surface transferrin receptor (CD71), a disulfide-bonded homodimeric glycoprotein of 180-190kDa. This mAb is highly specific to Transferrin Receptor / CD71 and shows no cross-reaction with other related proteins. Ligand for transferrin receptor is the serum iron transport protein, transferrin. This receptor is broadly distributed in carcinomas, sarcomas, leukemias, and lymphomas. CD71/Transferrin Receptor has been reported to be associated with cell proliferation in both normal and neoplastic tissues and useful in predicting clinical behavior or response to therapy in a number of malignancies including breast cancer.

Optimal dilution of the Transferrin Receptor antibody should be determined by the researcher.

Amino acids 94-212 (extracellular domain) of the human protein were used as the immunogen for the Transferrin Receptor antibody.

Store the Transferrin Receptor antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
