Transferrin proteins, iron-binding transporters, bind two Fe (3+) ions and an anion, usually bicarbonate. They transport iron from absorption and heme degradation sites to storage and utilization locations. Serum transferrin may impact cell proliferation. In microbial infection, Neisseria species utilize transferrin as an iron source, capturing and extracting iron for their metabolic needs. Transferrin Protein, Human (HEK293, His) is the recombinant human-derived Transferrin protein, expressed by HEK293 , with C-His labeled tag.
