Which is of higher quality: fetal bovine serum or newborn calf serum?

Publication date:2026-10-29

Fetal bovine serum is of the highest quality because, as the fetus has not yet been exposed to the external environment, it contains minimal levels of cell‑toxic components such as antibodies and complement. Bovine serum is the most widely used natural medium in cell culture; it is rich in essential nutrients required for cell growth and is commonly employed for the in vitro cultivation of animal cells, where it performs critically important functions.
