Fetal bovine serum (FBS), also known as fetal calf serum (FCS), is a commonly used cell culture media supplement. It supplies growth factors, hormones, vitamins, and other nutrients that can support the proliferation and viability of cells in culture. The range of these factors provided by FBS enables the culture of a wide variety of cell types that may have uncharacterized culture requirements. Heat inactivation of FBS destroys potentially detrimental complement proteins while retaining the growth-promoting properties of the serum. Specialty grades of FBS are optimized for the culture of particular cell types such as hybridomas, embryonic stem cells, tetracycline-controlled expression systems, and hormone dependent cells for insulin- and estrogen-related research. Manufacturers of FBS control product variability by managing the raw material supply chain, adhering to consistent processing protocols, and rigorous testing to ensure low endotoxin, hemoglobin, and virus load. USDA-approved testing of FBS is important to certify the virus and disease safety of the source before importing animal material into the United States. USDA APHIS certification enables the use of our US origin serum for the manufacture and export of products outside of the USA.

Product Summary for Fetal Bovine Serum - TET Tested
TET Tested Fetal Bovine Serum is specifically designed for use in tetracycline / tetracycline derivatives-regulated gene expression systems in cultured cells. The tetracycline and tetracycline derivative contents of high quality FBS is measured, and only lots with undetectable levels are selected as TET Tested Fetal Bovine Serum. All lots of TET Tested FBS are manufactured in our ISO 9001:2015 certified facility.
Fetal Bovine Serum and other serum products should be stored and handled correctly to assure long-term stability and to preserve growth performance consistency throughout its shelf-life. In addition, heat inactivation of serum is frequently desired to inactivate complement within the serum. Below are protocol links for serum storage/handling and heat inactivation.

FAQs for Fetal Bovine Serum - TET Tested
-
Q: Should I use heat inactivated fetal bovine serum?
A: Heat inactivation, in general, decreases the growth promoting properties of the serum and causes increased formation of crystalline or flocculent precipitates (salts, proteins, lipids, fibrin, etc.) in the Fetal Bovine Serum (FBS) as well as in other serum products. In fact, for many cell culture applications, heat inactivation may be unnecessary. Warming the serum-containing medium to 37˚C prior to use, as is the practice in many cell culture laboratories, is often sufficient to inactivate heat-labile complement factors. Heat inactivated FBS is frequently used in immunological applications.Since every cell type has different growth requirements, the choice of whether to heat inactivate your serum or not must be made by the researcher. If you have concerns about whether to use heat inactivated serum with your cell line or not, perform a side-by-side comparison of cell growth with heat inactivated versus non-heat inactivated serum.

Q: What is the difference between Fetal Bovine Serum (FBS) and Fetal Calf Serum (FCS)?
A: There is no difference. These are different names for the same product. Serum derived from blood of bovine fetuses is referred to as Fetal Bovine Serum or Fetal Calf Serum.
