Human sTransferrin Receptor/sTfR Quantikine ELISA, RUO Summary

Background
The Quantikine Human sTfR Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human sTfR in serum and plasma. Results obtained using natural human sTfR showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human sTfR.
Specificity
This assay recognizes natural human sTfR.

Background

Transferrin receptors are transmembrane, homodimeric proteins that play a role in iron transport, uptake, and storage. TfR is an essential receptor, found on almost all cell types, regulated by intracellular iron concentration, and has a high affiinity for transferrin. Soluble TfR (sTfR) arises from the proteolysis of TfR into monomers that can be measured in plasma and serum. TfR2 has limited tissue distribution (hepatocytes and enterocytes), is regulated by the cell cycle, and binds transferrin poorly.
