Product Details anti-Transferrin Receptor Antibody (Biotin)

Specificity: ER-MP21 stains proliferating cells of all types as well as cells taking up iron for special needs, such as late erythroid precursors and some mature macrophages. The antibody inhibits the iron uptake and the proliferation of macrophage precursors from bone marrow and early macrophage precursor cell lines. ER-MP21 recognizes the transferrin receptor but does not compete with transferrin binding. The antigen is a 200 kDa protein (non-reducing conditions) consisting of two identical chains. The recognized epitope of the receptor is not located at the transferrin binding site. Antigen Distribution: Macrophage progeny at day 7 in bone marrow cultures, treated in parallel on various days by irradiation (1500 rad 60Co γ-radiation) or addition of ER-MP21 (30 μg/mL final concentration). Cell numbers were quantified using the MTT assay and expressed relative to untreated controls. Relative growth inhibition calculated from data represented in left figure. For mAbor radiation treated cultures, the number of cell cycles needed to reach the cell number in untreated controls was calculated. Values obtained for irradiated cultures were taken as 100 % inhibition controls and values for ER-MP21 - treated cultures were expressed relative to these (See Figure. 1).

Target Details for Transferrin Receptor

Target: Transferrin Receptor (TFRC) (Transferrin Receptor (p90, CD71) (TFRC))

Alternative Name: CD71 / TFRC

Background: The transferrin receptor has been structurally characterized as a sulfide bound dimer of identical glycoprotein subunits of 95 kDa. The transferrin receptor is not present on resting blood lymphocytes. On PBL, the receptor appears after activation. The expression of transferrin receptor is coordinately regulated with cell growth. Present on T and B cell lines. The soluble (or serum) transferrin receptor (sTfR) is a circulating truncated form of the membrane receptor protein, it is an 85 kDa glycoprotein forming in serum a 320 kDa complex with diferric transferrin. The most important clinical use of the sTfR determination is in the differential diagnosis between iron deficiency anaemia and the anaemia of chronic disease.Synonyms: TfR1, Transferrin receptor protein 1, p90
