Fetal Bovine Serum (South America). Charcoal Stripped - 100ml Reference: S181F-100 Fetal Bovine Serum (FBS) South America, Charcoal Stripping: Charcoal / Dextran stripping reduces the concentration of steroid hormones in serum such as estradiol, progesterone, cortisol, testosterone, T3 and T4. This serum is usefull where there endogenous molecules may interfere with experimental works. This serum may show some reduced growth promotion ability for cells requiring the presence of certain hormones.
Fetal Bovine Serum (South America). Heat Inactivated - 100ml Reference: S181H-100 Fetal Bovine Serum (FBS) South America, Heat Inactivation (56°C-3min.): This treatment allows to destroy the complement acting in the immune system to avoid an interference with some experimentation, in particular the tests of immunology. It allows also to inactivate viruses and to destroy some bacterial contaminants such as the mycoplasma.
Fetal Bovine Serum (South America). Heat Inactivated - 500ml Reference: S181H-500 Fetal Bovine Serum (FBS) South America, Heat Inactivation (56°C-3min.): This treatment allows to destroy the complement acting in the immune system to avoid an interference with some experimentation, in particular the tests of immunology. It allows also to inactivate viruses and to destroy some bacterial contaminants such as the mycoplasma.
Fetal Bovine Serum (South America). Lipid Depleted - 100ml Reference: S181L-100 Fetal Bovine Serum (FBS) South America, Lipid Depletion: Biowest uses the fumed silica precipitation method for removing lipids. The fumed silica powder is added to the serum. It's well mixed together. After the solution is centrifuged. The supernatant contains the serum and the lipids are with the silica in the pellet.

Fetal Bovine Serum (South America). Iron Supplemented - 500ml Reference: S181R-500 Fetal Bovine Serum (FBS) South America, Iron supplementation: A 1% Ferric citrate sterile solution is added to the serum at ,246% (v/v). Then the serum is well mixed. Transferrin is normally 2 to 4 % bound to iron.
Fetal Bovine Serum (South America). Embryonic Stem Cells tested - 100ml Reference: S181S-100 Fetal Bovine Serum (FBS) South America, Embryonic Stem Cells tested: The serum is tested with Mouse Embryonic Stem Cell E14. Pre-screening of the serum is an essential procedure before using it for the culture of mouse Embryonic Stem cells (mES). mES Cell Qualified FBS are manufactured for maximum in vitro growth. When growing ES Cells, one of the most important parameters is the maintenance of the mouse embryonic stem cells in the undifferentiated state. Research requires the highest possible serum purity to prevent adverse differentiation. An external laboratory pre-screens FBS batches to eliminate the time-consuming and costly process of testing and re-testing. Each batch of sera is pre-screened for: Plating Efficiency and Proliferation, Morphology, Pluripotency markers by FACS analysis : SSEA-1, SOX2, OCT-3/4 and alkaline phosphatase (AP). The results are compared to a control lot of serum. The biological performance is assessed using cell culture medium supplemented with a final concentration of 12% serum.
