Why is FBS so expensive?
Due to increased demand and limited availability, the price of FBS has increased by greater than 300% in the past few years. These FBS alternatives are more readily available, cost less, and are associated with less ethical concerns, thus making them attractive alternatives to FBS in cell culture systems.
What is the difference between FBS and BSA?
Is Bovine Serum Albumin (BSA) and Fetal Bovine Serum (FBS) the Same Thing? Nope. It’s not the same. The benefit of FBS for cell culture is its lower antibody levels and higher growth factor levels.
Why FBS is used in cell culture?
Fetal bovine serum (FBS) is used as a growth supplement for the in vitro cell culture of eukaryotic cells. FBS contains growth factors and very low levels of antibodies, allowing for versatility in many different cell culture applications.
Can I use horse serum instead of FBS?
Therefore horse serum is the ideal supplement in nutrient media used for in vitro growth of specific hematopoietic progenitors. Applications: Cost effective alternative to FBS. growth of specific hematopoietic progenitor stem cells.
Why do we heat inactivate FBS?
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 [24], and other potential unknown inhibitors of cell growth.

Does FBS contain IgG?
FBS with low IgG is used for antibody production, recombinant protein synthesis and other applications. Stem cell culture has stringent requirements in terms of growth factors. Some of the growth factors present in FBS promote stem cell differentiation.
Does bovine serum albumin expire?
THIS PRODUCT IS NOT INTENDED FOR HUMAN OR THERAPEUTIC USE. To effectively preserve the integrity of BSA, it should be stored at the recommended temperature and protected from light.

Does FBS contain BSA?
Bovine serum albumin (BSA) is a major component of FBS (approximately 2.5 mg/ml in FBS [14. Albumin and mammalian cell culture: implications for biotechnology applications.
Which FBS for cell culture?
What is FBS used for? Fetal bovine serum (FBS) is used as a growth supplement for the in vitro cell culture of eukaryotic cells. Animal sera—both bovine and non-bovine sera—are used in cell culture applications with the most widely used being fetal bovine serum (FBS).
How long can you keep FBS in the fridge?
Liquid FBS and other serum may be stored refrigerated (2 to 8 °C) up to four weeks.
Should FBS be filtered?
It is not necessary, since comercial FBS is usually sterile – You can see this information in the package.
