• Gene Names: TF; TFQTL1; PRO1557; PRO2086
• Purity: Highly Purified; 97% as determined by cellulose acetate
• Synonyms: Transferrin; Bovine; Iron Unsaturated; Iron Unsaturated (APO); TF protein

• Purity/Purification: Highly Purified; 97% as determined by cellulose acetate
• Form/Format: Supplied as a lyophilized powder without additives.

• Application Notes: Bovine Transferrin is a crucial component for the cultivation of mammalian cells in-vitro. Bovine Transferrin is Critical for long-term cells growth in-vitro. Bovine Transferrin is used as detoxificant in media by binding contaminating metal ions. Bovine Transferrin is often used as a nutrient in fermentation media for recombinant protein and biopharmaceutical production. Additional common uses of Bovine Transferrin are: Molecular weight, Affinity purification of anti-human transferrin antibodies and also as receptor mediated transfection of molecules such as DNA, into cells.
• Solubility: It is recommended to reconstitute the lyophilized Bovine ATF in sterile 18M -cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Preparation and Storage: -20 degree C; Stability: Lyophilized Bovine ATF although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution Bovine ATF should be stored at 40C between 2-7 days and for future use below -180C. Please avoid freeze-thaw cycles.

Related Product Information for TF protein

Iron free Bovine Apo Transferrin is a glycoprotein of approximately 80kD. Transferrin is the iron-transport protein of vertebrate serum and donates iron to cells through interaction with a specific membrane receptor, CD71. Transferrin appears to be indispensable for most cells growing in tissue culture. It is referred to frequently as a growth factor because, in analogy to other growth factor-receptor interactions, proliferating cells express high numbers of transferrin receptors, and the binding of transferrin to their receptors is needed for cells to initiate and maintain their DNA synthesis. Apart from its role as an iron transport protein transferrin acts as a cytokine and has functions that may not be related to its iron-carrying capacity.

NCBI Description

This gene encodes a glycoprotein with an approximate molecular weight of 76.5 kDa. It is thought to have been created as a result of an ancient gene duplication event that led to generation of homologous C and N-terminal domains each of which binds one ion of ferric iron. The function of this protein is to transport iron from the intestine, reticuloendothelial system, and liver parenchymal cells to all proliferating cells in the body. This protein may also have a physiologic role as granulocyte/pollen-binding protein (GPBP) involved in the removal of certain organic matter and allergens from serum. [provided by RefSeq, Sep 2009]

Uniprot Description

TF: Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate. It is responsible for the transport of iron from sites of absorption and heme degradation to those of storage and utilization. Serum transferrin may also have a further role in stimulating cell proliferation. Defects in TF are the cause of atransferrinemia (ATRAF). Atransferrinemia is rare autosomal recessive disorder characterized by iron overload and hypochromic anemia. Belongs to the transferrin family.
