Fetal Bovine Serum (South America). Dialysed - 500ml Reference: S181D-500 Fetal Bovine Serum (FBS) South America, Dialysation: The dialysis reduces the concentration of free low molecular weight components such as nucleotides, amino acids, hormones and ions. We use a dynamic filtration method to produce our dialysed serum. The sera are dialysed using a 1 Da molecular weight cut-off membrane.
Fetal Bovine Serum (South America). Charcoal Stripped - 500ml Reference: S181F-500 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). 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.
