Tissue culture scientists need to have complete confidence that the serum they use meets their specific needs, and that properly validated procedures have been used to demonstrate this. It is therefore important that all operations from the animal blood to the finished product are quality controlled and fully documented.
Thorough biological testing is carried out to assure performance and to eliminate potential biological hazards.

1.14: Bovine Serum Albumin
Bovine Serum Albumin is a large, stable, soluble, monomeric, globular protein which makes up about half of the total serum protein. Due to its binding and transporting properties, BSA acts primarily as a carrier protein for hormones, fatty acids, trace minerals, vitamins and iron. However, it also plays a role in stabilising extracellular fluid volume and maintaining osmotic balance, as well as binding harmful toxins and free radicals.
Its in vitro uses are diverse, ranging from pharmaceutical and medical applications to agriculture and chemical manufacture.
