Description :
| Clone 66IG10 | Isotype IgG1 | Product Type Primary Antibodies | Units 0.1 mg | Host Mouse (Balb/c) | Species Reactivity Human | Application Flow Cytometry Immunohistochemistry (frozen) Immunoprecipitation Western Blotting

Background :
66IG10 is a Mouse monoclonal IgG1 antibody derived by fusion of SP2/0 Mouse myeloma cells with spleen cells from a BALB/c Mouse immunized with Human T-cells.

Source :
Transferrin receptor protein 1 (TfR1) also known as CD71 (Cluster of Differentiation 71) is a protein that in Humans is encoded by the TFRC gene. CD71 plays a critical role in cell prolifeRation by controlling the supply of iron, which is essential for many metabolic pathways, through the binding and endocytosis of transferrin, the major iron-carrying protein. The expression of CD71 is regulated at the post-transcriptional level through the control of mRNA stability and is closely linked to intracellular iron levels. Nitric oxide can affect CD71 expression independently of intracellular iron concentRation by activating proteins which then stabilize CD71 mRNA. Expression of CD71, or the transferrin receptor, is very low on resting leukocytes but is upregulated upon activation reflecting the iron dependence of activation. In other tissues, CD71 is expressed on most dividing cells and also on brain endothelium and alveolar macrophage. The ligand is the Serum iron transport protein transferrin. CD71 antibodies are used as an indiCator of prolifeRation in the typing of lymphomas and leukemias. <

Product :
Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide. Formulation: Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.

Specificity :
66IG10, raised anti Human thymocytes (T-cells) was found to be directed anti the Human transferrin receptor. This antibody reacts with the transferrin receptor, a 180-190 kD transmembrane glycoprotein which exists as a 95 kD homodimer with interchain disulfide bond.

Applications :
66IG10 is useful for western blot (on non reduced antigens) and immunoprecipitation, flow cytometry and immunohistochemsitry on frozen sections. Optimal antibody dilution should be determined by titration.

Storage :
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.

Caution :
This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving humans or animals. It may contain hazardous ingredients. Please refer to the Safety Data Sheets (SDS) for additional information and proper handling procedures.

Antibodies are immunoglobulins secreted by effector lymphoid B cells into the bloodstream. Antibodies consist of two light peptide chains and two heavy peptide chains that are linked to each other by disulfide bonds to form a “Y” shaped structure. Both tips of the “Y” structure contain binding sites for a specific antigen. Antibodies are commonly used in medical research, pharmacological research, laboratory research, and health and epidemiological research. They play an important role in hot research areas such as targeted drug development, in vitro diagnostic assays, characterization of signaling pathways, detection of protein expression levels, and identification of candidate biomarkers.
