Related Product Information for TF protein
Background: Transferrin is a monomeric glycoprotein found in plasma at an average concentration of 250 mg/100ml. The specific iron-binding protein in plasma, it has a role in the transportation and distribution of iron among the body organs, in iron metabolism and in prevention of iron loss via the kidney. Stored in bone marrow as TF-bound iron, it also possesses bacteriostatic and fungistatic activity. Clinically, decreases in transferrin are observed in congenital disorders, newborns, inflammatory diseases, hypo-proteinemias and nephritic syndrome; increases are found in pregnancy, iron-deficiency anemias and inoculation hepatitis. Transferrin is required by all types of cells in cultures for maximal growth. It is, therefore, an important factor used in defined culture media.
Product Categories/Family for TF protein
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.

Product Notes
The TF tf (Catalog #
AAA844065) is a Protein produced from Rat Plasma and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Apotransferrin can be used in a range of immunoassay formats including, but not limited to, SDS-PAGE. Researchers should empirically determine the suitability of the TF tf for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process.
It is sometimes possible for the material contained within the vial of
"Apotransferrin, Protein" to become dispersed throughout the inside of
the vial, particularly around the seal of said vial, during shipment and storage. We always
suggest centrifuging these vials
to consolidate all of the liquid away from the lid and to the bottom of the vial prior to
opening. Please be advised that
certain products may require dry ice for shipping and that, if this is the case, an
additional dry ice fee may also be
required.
