Application: | Transferrin human has been used: • to incubate human proximal tubule cells (HKC) - 8 cells along with IgG for the examination of albumin specificity • as a supplement in serum-containing/devoid medium for human thyroid cell culture • as a target glycoprotein to develop an in-gel hydrazinolysis method |
Biochem/physiol Actions: | Transferrin mediates iron transportation from plasma to cells. The iron-bound transferrin are of three forms: monoferric A/B transferrin and diferric transferrin. The transferrin binds to specific cell surface receptors and are internalized by endocytosis. Once inside, the iron is released into the cells and the iron-free transferrin, also referred to as apotransferrin, is exocytosed outside the cell without being degraded. Transferrin is known to deliver iron to cells in a physiologically safe and effective form. |
General description: | Transferrin is a glycoprotein with a branched carbohydrate chain, having two sites for ferric ion binding in its polypeptide chain. |
