Transferrin is a bilobed glycoprotein. The polypeptide chain of transferrin is composed of two homologous lobes i.e N- and C- lobes. Each lobe is made of two domains N1, N2 and C1, C2 which are linked by a hinge. It has two specific sites for binding of Fe3+.
Application
Anti-Transferrin antibody has been used:
in quantitative precipitin assay
in enzyme linked immunosorbent assay (ELISA)
in western blotting
in immunoblotting
Anti-Transferrin antibody produced in goat was used in western blotting analysis of HEK293 cell extracts.
Biochem/physiol Actions
Transferrin is the major iron transporter protein that binds Fe(+3). The transferring-iron import system consists of a TonB dependent transporter (TbpA), and a lipoprotein co-receptor (TbpB) and both proteins work together in the transport of iron across the membrane.
Transferrin plays a major role in providing iron as a source for haemoglobin synthesis. It binds to the transferrin receptor 1(TfR1).
Preparation Note

Cellular iron homeostasis is maintained by iron regulatory proteins 1 and 2 (IRP1 and IRP2). IRPs bind to iron-responsive elements (IREs) located in the untranslated regions of mRNAs encoding protein involved in iron uptake, storage, utilization and export. Over the

A proinsulin-transferrin (ProINS-Tf) recombinant fusion protein was designed and characterized for the sustained release of an active form of insulin (INS) by hepatoma cells. During incubation with H4IIE hepatoma cells, a gradual decline of ProINS-Tf concentration, with a concomitant generation
Two pathogenic species within the genus Neisseria cause the diseases gonorrhoea and meningitis. While vaccines are available to protect against four N. meningitidis serogroups, there is currently no commercial vaccine to protect against serogroup B or against N. gonorrhoeae. Moreover, the available
