Human transferrin is a glycoprotein which bind to and consequently mediate the transport of iron (Fe) and cell in serum with a molecular weight of 76 KDa. Serum-free cell culture systems require a form of iron delivery. Transferrin is the preferred delivery form of iron because cells can process transferrin-bound iron in a physiologically appropriate manner through transferrin receptors on the cell surface.
OsrhTF is a recombinant human transferrin derived from rice endosperm, which can provide bulk and stable supply, mainly used in serum-free cell culture to promote iron transport and cell growth. Compared with bovine-derived transferrin, OsrhTF is animal component free, can avoids the risk of contamination from human or animal-derived viruses and mycoplasma.
