Fetal Bovine Serum   Fetal bovine serum (FBS) is the liquid fraction of clotted blood from fetal calves, depleted of cells, fibrin and clotting factors, but containing a large number of nutritional and macromolecular factors essential for cell growth. Bovine serum albumin is the major component of FBS. Growth factors in FBS are essential for the maintenance and growth of cultured cells. FBS also contains a variety of small molecules like amino acids, sugars, lipids, and hormones. FBS is used in a wide range of applications. One of the primary uses of FBS is in eukaryotic cell culture, where it provides many essential nutrients and growth factors that facilitate cell survival and proliferation. However, it is important to note that FBS in human cell cultures may introduce research artifacts; human cells cultured with human sera behave differently from those cultured with FBS [3]. FBS is also used in the research, manufacture, and control of human and veterinary vaccines and of biotech drugs, and used to stop trypsin digest or to serve as a protectant in cryopreservation [5]. Cell culture media without any serum have been in use for many years. Fetal bovine serum might not be the best supplement for cell culture.

For example, bovine serum albumin with insulin-transferrin-sodium selenite and/or epidermal growth factor in the culture medium improves bovine embryo quality and trophoblast invasion as compared to fetal bovine serum. Why is fetal serum used vs. for example, newborn serum or adult serum?  

Fetal serum contains more growth factors:

and has lower gamma globulin (i.e., antibodies) content and non-fetal serum. These are important because the growth factors facilitate cell survival and proliferation while antibodies could bind to the cells in culture. In addition, fetal serum contains lower levels of complement proteins (complements) than those from adults or newborns. These complements have the undesirable effects of living cells in culture and interfering with immunoassays. What is the difference between serum and plasma?   Serum and plasma are both derived from whole blood by using centrifugation to remove components including red blood cells. The difference between plasma and serum is that coagulation proteins are present in plasma but have been removed from serum. Plasma is generally prepared by adding anti-coagulants to the blood before centrifugation, but the clotting proteins are not removed. Serum is prepared by allowing the blood to coagulate before centrifugation or by extensive/progressive centrifugation. Thus fibrinogen and proteins associated with clotting are not present in serum.

In humans, the following 22 proteins comprise 99% of the total protein content of serum and plasma: albumin, total IgG, transferrin, fibrinogen, total IgA, alpha-2-macroglobulin, total IgM, alpha-1-antitrypsin, C3 complement, haptoglobin, alpha-1-acid glycoprotein, apolipoprotein-B, apolipoprotein-A1, lipoprotein (a), factor H, ceruloplasmin, C4 complement, complement factor B, pre-albumin, C9 complement, C1q complement, and C8 complement [7, 8]. The remaining 1% includes hundreds of proteins. The most abundant serum protein, albumin, at 50 mg/ml, comprises about half of the total protein mass. How is fetal bovine serum tested before being packaged and sold?   The International Serum Industry Association (ISIA; www.serumindustry.org), a trade organization of serum providers, established guidelines for quality control standardization. These guidelines require the following tests be performed using specific methodologies, and the test results must be available as the Certificate of Analysis Test bacteria and fungi – sterility testing mycoplasma cytopathic agents – viral testing hem adsorbing agents – viral testing bovine virus diarrhea – viral testing pH measurement Osmolality total protein, determined by the Biuret method Endotoxins hemoglobin electrophoretic patte performance testing, such as stem cell culture radial immunodiffusion immunoglobulin gamma-glutamyl transferase (GGT) Table 1. Minimum serum test requirements. Endotoxin testing Endotoxins, also called lipopolysaccharide (LPS) or lipooligosaccharide (LOS), comes from the outer membranes of Gram-negative bacteria and contributes to the clinical manifestations of a variety of pathogenic Gram-negative bacteria. In vivo, endotoxins induce fever and the inflammatory response while in cell culture they introduce variation in cellular responses. Endotoxin levels are measured by the limulus amebocyte lysate (LAL) test. Amebocytes are analogous to white blood cells in vertebrates and LAL is prepared from the blood of Limulus Polyphemus (American horseshoe crab;  1). LAL is very sensitive to endotoxins and coagulates in the presence of even a minute amount of endotoxin. The conservation status of the American horseshoe crab has been assessed [10] and discussed in popular culture [11]. Many of the horseshoe crab’s populations are at risk and thus care should be taken to protect them from loss. Fetal Bovine Serum

Specialty sera and other treatment We discuss some of commonly used specialty area below. Serum preparations dedicated to specific research topics, such as lipoprotein-deficient serum from Kalen Biomedical for cholesterol research [12], or for specialized gene expression systems, such as tetracycline-screened fetal bovine serum [13], are not discussed. FBS depleted of exosomes or other components Regular FBS contains a large number of extracellular vesicles, some of which are exosomes [14, 15]. When performing exosome research with cultured cells, it is critical to use FBS without exosomes. However, it is important to be aware that exosome-depleted FBS may affect and support cell growth differently than regular FBS [16, 17]. Exosome-depleted FBS can be either purchased directly from several commercial suppliers or prepared through either ultracentrifugation or ultrafiltration, though the effects of the depletion processes and/or the commercial sources may not be consistent in terms of cell growth and physiology Other components of FBS can be depleted, depending on the experimental requirements. For example, Galmozzi A et al depleted heme from FBS with ascorbic acid Heat inactivation A common treatment of FBS is heat-inactivation, where FBS is heated at 56°C for 30 minutes in a water bath with occasional shaking. The purpose is to inactivate whatever components of the complement system are present in the FBS [20], and other potential unknown inhibitors of cell growth. Previously heat-inactivation was also intended to remove mycoplasma contamination, which is no longer an issue since all serum products are now filtered through pore sizes small enough to remove mycoplasma. It must be noted that heat-inactivation may have undesired effects as well, such as reducing the ability of cultured cells to attach to surfaces Several suppliers have urged users not to heat-inactivate FBS for most cell culture needs. In each case it is advisable to evaluate the need for heat inactivation in a particular application, since different cells have different responses towards heat-inactivation of FBS Furthermore, like all other protocols with regard to FBS, the heat inactivation process must be done with care, since a temperature too high or prolonged heating will inactivate growth factors and generate precipitates. Aikawa T et al cultured mouse primary glial cells on poly-D-lysine-coated flasks in DMEM containing 10% heat-inactivated FBS from MilliporeSigma (F2442) [26]. Feldman D et al cultured HEK293FT cells in DMEM supplemented with heat-inactivated fetal bovine serum from Seradigm (97068-085), and A549, HCT116, HT1080, A375 cells with heat-inactivated fetal bovine serum from Sigma (F4135) to evaluate optical pooled screens [13]. Kulkai S et al maintained Hut-78 cells with heat-inactivated fetal bovine serum from Atlanta Biologicals Charcoal treatment Activated carbon can bind to lipophilic molecules and thus has been used to remove hormones such as androgen, estradiol, progesterone, cortisol, testosterone, triiodothyronine (T3), and thyroxine (T4) from FBS. These serum lipid hormones tend to interfere with immunoassay systems and insulin assay methods. Thermo Scientific HyClone (now GE Healthcare) charcoal stripped fetal calf serum (csFCS) was used to culture cells in order to identify TGF beta family members Dialysis Dialysis can remove all molecules with molecular weight less than 10,000 MW from FBS. This includes both polar and non-polar molecules. Hormones, cytokines, glucose, amino acids, and many others are removed. Dialysis also removes antibiotics and other exogenous molecules in FBS. Dialyzed FBS from Thermo Fisher Scientific was used in the culture of pancreatic ductal adenocarcinoma for SILAC mass spec study [29] and other SILAC studies [30] and in the culture of HeLa cells with Met analogue l-AHA pulse-chase for the click-chemistry detection of long-lived proteins Gamma-Irradiation Gamma irradiation can be part of the process to sterilize FBS. FBS is usually filtered through 0.1 um filters multiple times to eliminate microorganisms. Gamma irradiation can inactivate the viruses commonly present in bovine species. However, some viral species, such as parvovirus, are resistant to gamma-irradiation. Low IgG Though FBS has a quite low IgG content, even this level may be too high for some certain applications. The IgG level can be substantially reduced further by capture chromatography. FBS with low IgG is used for antibody production, recombinant protein synthesis and other applications. Stem cell culture Stem cell culture has stringent requirements in terms of growth factors. Some of the growth factors present in FBS promote stem cell differentiation. Several companies offer embryonic stem cell qualified FBS intended to maintain the undifferentiated stem cell. However, it is important to test specific lots of for their applicability in maintaining the pluripotency/totipotency of different types of stem cells. Country of origin Major cattle countries are the main providers of FBS. The countries include the US, Australia, New Zealand, Canada, several in South and Central Americas The production and collection of serum products are regulated by govement agencies. FBS is labeled as USDA-Grade or European-Grade. USDA-Grade FBS can be imported into any country free of bovine spongiform encephalopathy and foot and mouth diseases, while European-Grade FBS can be sold in most European and Asian countries How to take care of/store fetal bovine serum? FBS is best stored frozen, between -5 to -20°C, and can be thawed at a temperature between 2 to 8°C. It is often useful to aliquot and freeze the serum in smaller portions, often 50 ml tubes, to avoid many freeze and thaw cycles. Occasionally, some aliquots of FBS remain in a liquid at freezing temperatures. This is due to the lack of a nucleation center (particulate matter) for the crystallization (freezing) to start. If you simply flick the tubes with your finger, they usually solidify almost instantly. It is common to have some precipitate after thawing. The precipitates, likely due to denaturation of some of the serum proteins, can be cleared by brief centrifugation, and this generally does not affect the quality of the serum. Selection of fetal bovine serum Many suppliers provide FBS with different grades, country of origin, and treatment. FBS, itself, is a complex mixture, and variability between different grades, suppliers, and lots is to be expected. Thus, it is essential to establish a process for selecting and evaluating FBS. It is a good idea to examine the literature to determine how a particular selection of FBS was previously used in similar research or for the same cell culture and to pay close attention for potential lot-to-lot variation in the FBS. To assist with this, Labome has conducted a survey of FBS usage from scientific publications, discussed below, to help our visitors to select the most suitable FBS. Fetal Bovine Serum in the Literature Labome surveys literature for the materials used. Here the publications that cited fetal bovine serum are summarized.
