Merck, T2252-1G, apo-Transferrin human

General description
Transferrin is a bilobed glycoprotein containing an N-terminal lobe and a C-terminal lobe. Each of these domains is divided into two sub-domains and within the inter subdomain cleft is the metal-binding site. A single transferrin molecule can bind to two ferric ions. Apo-transferrin is an iron-free form.
Application
Apo-transferrin has been shown to strongly inhibit bacterial adhesion to biomaterials including polystyrene, polymethylmethacrylate, and silicone. Inhibition was seen at twenty micrograms/ml in culture medium.
apo-Transferrin human has been used in Dulbecco′s Modified Eagle Medium/Nutrient Mixture F-12 to culture:
pancreatic ductal adenocarcinoma (PDAC) cell lines
oligodendrocytes
renal proximal tubule epithelial cells (RPTEC/TERT1) cells

Biochem/physiol Actions
Transferrin transports iron through receptor-mediated endocytosis. The iron transport mechanism occurs in the endothelial cells of the blood-brain barrier. Transferrin maintains iron homeostasis and is an iron-associated marker. Reduced levels of transferrin are observed in severe COVID-19 conditions. It may bind to other molecules apart from iron, hence it can be used in targeted drug delivery.
Other Notes
Non-heme iron-transport protein.
