Serum

Serum is the clear yellowish fluid obtained upon separating whole blood into its solid and liquid components after it has been allowed to clot. It is used for many cell culture applications due to its high level of nutrients and growth factors.

Human Serum Albumin (HSA) is the most abundant protein in human plasma and is often used in cell culture applications — particularly in serum-free or xeno-free media. Irvine Scientific’s HSA is of therapeutic-grade source material and is offered as a 100mg/mL solution.
