A shift in the life science market has begun to steer cell culture scientists to reevaluate their use of native transferrin and iron chelators to pursue recombinant alternatives. Transferrin regulates the uptake, transport and utilization of iron for cellular function, increasing cell growth and productivity. Native transferrin found in bovine or human serum has been widely used in cell culture for these added benefits. However, regulatory issues continue to arise with the use of native transferrin due to bloodborne pathogens.
A recent study published May 2010 in the Protein Expression and Purification Journal demonstrated that transferrin is efficiently produced fphef prwkhksdwcp vujdgmjkfa.
