Transferrin (TF) is the primary iron-containing protein in plasma, which not only participates in iron transport and metabolism, but also regulates respiration, cell proliferation, and the immune system. It also possesses antioxidant and antibacterial protective functions, making it widely used in cell culture. Transferrin exists in three forms: apo (not bound to iron ions), holo (bound to two iron ions), and partially saturated. This product is a recombinant human transferrin expressed and purified from Pichia yeast using gene recombination technology. It does not contain animal-derived components and poses no risk of blood-borne viral infections, with high batch stability. This transferrin is in its apo form, suitable for use in iron-rich culture media.
