Fetal Bovine Serum (FBS) is the liquid part of blood remaining after the removal of the cellular fraction and coagulation factors. It is extracted by centrifuging aseptically collected, coagulated fetal bovine blood. Sterile FBS is obtained through triple filtration at 0.1µm.
FBS contains proteins and growth factors essential for maintaining and proliferating eukaryotic cells in vitro. It also includes attachment factors that create a “coating” effect on plastic surfaces, enhancing cell adhesion. These components make FBS indispensable in cell culture.
Biosera offers charcoal/dextran stripped FBS for researchers needing low levels of various hormones. Charcoal/dextran stripping reduces the concentration of steroid hormones in serum, such as estradiol, progesterone, cortisol, testosterone, T3, and T4. This serum is useful when endogenous molecules may interfere with experimental work.
All FBS batches are tested for endotoxin and mycoplasma levels, specific viruses (BVD), hemoglobin, total protein content, and cell culture performance.
Origin: South America
The serum is collected or imported and processed in accordance with European regulations.
Biosera ensures the accuracy of geographic origins.
