Why is FBS used in cell culture?
The primary use of FBS is a supplement for in vitro cell culture. Its unique biological makeup promotes rapid cell growth, thus making it a product that yields a high efficacy.
Can I grow cells without FBS?
Yes, you don’t need FBS. In fact, probably better without FBS (which has differentiation factors). “MCF-7 were grown as tumourspheres by adapting the growth medium and methods used to culture neural stem cells in the neurosphere assay (NSA) [4]. All cells were grown at 37°C in 5% CO2.
Why is fetal calf serum used in mammalian cell and tissue culture?
Benefits of fetal bovine serum Serum is added to culture medium at a concentration of 2-10% to provide attachment factors, nutrients, and hormones for mammalian cells, as well as to be a buffer against disruptions like pH changes and endotoxins.
What FBS means?
HyClone Defined Fetal Bovine Serum (FBS), US Origin Fetal bovine serum (FBS) is a nutrient-rich cell culture supplement that is high in growth factors and low in antibodies, compared to non-fetal sera.
Is fetal bovine serum a buffer?
The growth promotion assay measures the ability of each FBS lot to support proliferation of fastidious human diploid fibroblasts through multiple subcultures. Serum acts as a buffer in the cell culture system; the pH is tested to ensure accurate cell culture quality and performance.
Does FBS contain BSA?
Bovine serum albumin (BSA) is a major component of FBS (approximately 2.5 mg/ml in FBS [14]), which has been shown to bind free unsaturated fatty acids and to interfere with ΔΨm in potato mitochondria [15] and in mammalian cells [16].
What proteins are found in FBS?
The major component of FBS is serum albumin which constitutes 60 to 67% of total proteins. Other abundant proteins include cone cGMP-specific 3′,5′-cyclic phosphodiesterase R-subunit, alpha-1-antiproteinase, plasminogen and lactoperoxidase.
Can I use horse serum instead of FBS?
Horse Serum contains more immunoglobulins than fetal bovine serum (FBS), has an increased protein content, and is a cost-effective alternative to fetal bovine serum. Horse Serum is used for diagnostic assays, supplementation during mycoplasma growth, or for cultivation of hematopoietic stem cells and neuronal cells.
Is serum necessary for cell culture?
Serum is vitally important as a source of growth and adhesion factors, hormones, lipids, and minerals for the culture of cells in basal media. In addition, serum also regulates cell membrane permeability and serves as a carrier for lipids, enzymes, micronutrients, and trace elements into the cell.
Is calf serum the same as FBS?
Fetal Bovine Serum is the same as Fetal Calf Serum. There is no difference and semantics have no place in science, and anyone working with cells should know that.
Can we keep FBS in UV?
However, you should take into account that FBS composition is different from lot to lot. Also, if your culture medium is in a plastic or glass vessel it will be protected from standard laminar hood UV light. The plastics and glasses strongly attenuate the amount of UV that can get through.
Why is FBS heat inactivation?
Why Use Heat-inactivated Fetal Bovine Serum? The objective of heat inactivation is to destroy complement activity in the serum without affecting the growth-promoting characteristics of the product.
What is the pH of Fetal Bovine Serum?
a Serum-starved cells were incubated for 24 h in medium A at pH 7.25 and 6.81 and with or without FBS (10%), genistein (100 lM) and mitomycin (4 lg/ml). Protein content of control samples (pH o 7.25) was taken as 100%.
Is there insulin in FBS?
A total of 143 proteins were identified in FBS, among which 14 proteins including insulin-like growth factor 2 (IGF-2) and IGF binding protein (IGFBP)-2 and -6 were reduced in CS-FBS.
How much BSA is there in FBS?
approximately 2.5 mg/ml
Bovine serum albumin (BSA) is a major component of FBS (approximately 2.5 mg/ml in FBS [14]), which has been shown to bind free unsaturated fatty acids and to interfere with ΔΨm in potato mitochondria [15] and in mammalian cells [16].
Is bovine calf serum (BCS) the same as FBS?
But before we do, allow me to take this time to clear something up: FBS = FCS. Fetal Bovine Serum is the same as Fetal Calf Serum. There is no difference and semantics have no place in science, and anyone working with cells should know that. So as I complete my descent from my uppity soapbox, I’ll bring up Bovine Calf Serum (BCS).
What is the difference between FBS and FCS?
This means the serum comes from a calf after it is born rather than before. So FBS and FCS are the same and both fetal, but different to BS or CS which would come from a calf already born. It is Bovine serum and Calf serum, there is no different but I believe there is a different in preparation.
Is FBS only for cell culture?
A quick Google search suggests that FBS is only really used for cell culture. We knew that, so it’s time to move on… But before we do, allow me to take this time to clear something up: FBS = FCS. Fetal Bovine Serum is the same as Fetal Calf Serum.
What is the difference between fetal bovine serum and fetal calf serum?
As the commenter before me stated, there is no difference between fetal bovine serum (FBS) and fetal calf serum (FCS). It is my understanding that the name FCS was more commonly used in the past while FBS is now more commonly used. I haven’t come across the term bovine calf serum before, but FBS is harvested from a bovine fetus (hence the name).
