Description and Uses
Holo-transferrin is the transferrin of the holo iron. It is a kind of iron-binding blood plasmaglycoproteins that is capable of regulating the level of free iron (Fe) in biological fluids. It is responsible for iron transportation in vertebrate serum and donating irons to cells through interaction with the CD71 membrane receptor. Transferrin is crucial for proliferating cells as a growth factor to initiate and maintain the DNA synthesis. It can also act as a cytokine. It is mainly synthesized in liver inside the human body. It is responsible to deliver iron from duodenum and white blood cells macrophages to all the other tissues, and is a key protein to maintain in vivo iron homeostasis. Increased plasma transferrin level is related to diseases such as iron deficiency anemia while decrease plasma transferrin is related to iron overload diseases and protein malnutrition.
All cells require iron for the proper uptake of oxygen from their environment. Transferrin, a protein isolated from serum, causes the uptake and transport of iron from culture medium to the cells. This allows proper oxygen uptake and also stimulates growth-related enzyme activity. Iron-saturated transferrin (holo transferrin) is continually recycled after releasing iron and becomes iron-deficient transferrin (apo-transferrin). Choosing which form to use depends upon the culture conditions. In media such as Dulbecco′s Modified Eagle′s Medium/Ham′s Nutrient Mixture F12 (DMEM/F12) that contain high levels of iron salt, using apo-transferrin is preferred.
