Description générale

Transferrin (TF) belongs to the family of bilobal glycoproteins which tightly bind ferric iron. Each of the homologous N- and C-lobes of the protein contains a single iron-binding site present in a deep cleft.

Immunogène

Serotransferrin precursor recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Actions biochimiques/physiologiques

Transferrin (TF) serves as the iron transport protein in the blood. Iron is transported in the serum by binding to circulating transferrin, which in turn binds to receptors on the cell surface. At the alkaline extracellular pH of 7.4, TF binds one or two ferric ions and two iron-bound TF molecules can bind the dimeric transferrin receptor (TfR). At this pH, iron-free transferrin is not recognized by TfR. This is followed by an endocytotic pathway involving the TfR, where the entire complex is internalized by endocytosis. When the pH is reduced in the cell, iron is released from TF leading to a conformational change in each lobe. Two critical lysines in the N-lobe of TF aid this conformational change allowing entry of a chelator to capture the iron. Finally, the complex gets back to the cell surface and the extracellular pH causes the dissociation of the apo-TF molecules from the receptor.

Caractéristiques et avantages

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
