It recognizes a ~90-95kDa protein which is identified as cell surface transferrin receptor (CD71), a disulfide-bonded homodimeric glycoprotein of 180-190kDa. This MAb is highly specific to 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 recombinant CD71 antibody should be determined by the researcher.

A recombinant human partial protein (extracellular region, amino acids 94-212) was used as the immunogen for this recombinant CD71 antibody.

Store the recombinant CD71 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
