Product Overview
Clone AOAA-20 is a rabbit monoclonal antibody that recognizes transferrin receptor protein 1 (gene TFRC) in human, mouse and rat samples and is validated for Western blot, IHC, immunoprecipitation and flow cytometry. The predicted molecular weight is 84.9 kDa, and the supplier reports an observed band at about 95 kDa.
Transferrin receptor 1 (TFRC, CD71) is a homodimeric membrane receptor that takes up iron-loaded transferrin by endocytosis, releases the iron in acidified endosomes and then recycles to the cell surface. It is essential for erythropoiesis, is highly expressed on dividing cells and is widely used as a proliferation and erythroid marker.

Samples with a confirmed band (WB): human HeLa cells, human U-87MG cells, rat liver tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human placenta tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human TFR.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places transferrin receptor protein 1 in the cell membrane and melanosome. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
