Bovine transferrin is widely used in cell culture applications as a supplement to promote cell growth and viability. It is particularly valuable in serum-free media, where it helps transport iron into cells, ensuring optimal metabolic activity and proliferation. This protein is also employed in research studies to investigate iron metabolism and its role in various biological processes. Additionally, bovine transferrin is utilized in the production of biopharmaceuticals, where it supports the growth of mammalian cells used in the manufacturing of therapeutic proteins and antibodies. Its ability to bind and regulate iron levels makes it a critical component in preventing oxidative stress and maintaining cell health in vitro.
