CD71/TFRC/Transferrin Receptor Antibody (H68.4): sc-65882

CD71 Antibody (H68.4) is a mouse monoclonal IgG1 kappa light chain antibody that detects CD71 protein in mouse, rat, and human samples through western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and flow cytometry (FCM). Anti-CD71 antibody (H68.4) comes in non-conjugated form and various conjugates, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. CD71, also known as transferrin receptor (TFR), is a type II membrane glycoprotein forming a disulfide-linked homodimer of identical subunits. CD71 maintains iron homeostasis by binding to transferrin, a serum iron-transport protein, and enables cellular iron uptake through receptor-mediated endocytosis. CD71 shows high expression in proliferating cells, reticulocytes, and erythroid precursors, while remaining absent in resting leukocytes but becoming upregulated when lymphocytes, monocytes, and macrophages activate. CD71 appears on most dividing cells and brain endothelium, playing key roles in hematopoiesis and neurobiology. A second transferrin receptor, TFR2, also facilitates transferrin-bound iron uptake, primarily expressing in liver hepatocytes and erythroid precursors. TFR2 gene mutations lead to hereditary hemochromatosis type III (HFE3), an iron overload disorder common among Caucasians, highlighting CD71′s significance in health and disease.
