Application and Effect

Iron(III) Citrate is an integral part of the structural basis of gating by the outer membrane receptor FecA from Escherichia coli. Binding of ferric citrate triggers a conformational change of the extracellular loops that close the external pocket of FecA.Ferric citrate is used as a component of protein-free medium. It is used as a substitute for transferrin in mouse hybridomas culture. Ferric citrate enhances IgM production. It indirectly stimulates the mitogen-activated protein kinase (MAPK) by favoring high amphiregulin oncoprotein levels in colon cancer.Ferric citrate is effective in binding to phosphate in patients with dialysis-dependent chronic kidney disease.
