Fetal Bovine Serum (FBS) and Other Animal Sera

Browse Fetal Bovine Serum, Human, Horse, Newborn Calf Serum, and Serum Replacements

Fetal bovine serum (FBS) contains embryonic growth factors that make it an excellent choice as a growth supplement in cell culture. Growth factors, hormones, proteins, vitamins, and trace elements in FBS have been shown to contribute to the metabolic requirements of cells. Many of these biomolecules regulate, enhance, or suppress growth in naturally occurring animal systems. When introduced to eukaryotic cell cultures at an appropriate concentration, FBS from clotted bovine blood or other sera can have a similar effect.

We offer a range of FBS products as well as serum replacement; pooled human serum; newborn, calf, and adult bovine sera; horse sera; and sera from other species such as chicken, goat, pig, rabbit, and sheep.

Search FBS products by country of origin, treatment (such as ultrafiltration, heat inactivation, or charcoal stripped), hemoglobin count, and endotoxin load. Most FBS sera is sterile-filtered and suitable for cell culture; some are specially prepared for hybridoma or insect cell culture.
