Fetal Bovine Serum (FBS) South America, Tetracycline Free – S181T

Fetal Bovine Serum (FBS) is the liquid part of the blood depleted of the cellular fraction and coagulation factors. It is extracted after centrifugation of coagulated fetal bovine blood collected aseptically. Sterile FBS is obtained by triple filtration of 0.1µm.

FBS contains proteins and growth factors allowing maintenance and proliferation of eukaryote cells in vitro. It also contains attachment factors that create a “coating” effect on the plastic of the support, thus increasing cell adhesion. It is an essential product in cell culture because of the different components it provides.

Tetracyclines are antibiotics usually used during bacterial infection, or to prevent disease development in cattle breeding. The impact of these treatments on FBS is the presence of residual tetracycline derivatives, wich can modify biological parameters or Tet-induced gene expression. Biowest Tetracycline-free Serum is tested for the presence of chlorotetracycline, oxytetracycline and tetracycline.

All FBS batches are tested for endotoxin and mycoplasma levels, specific viruses testing (BVD), hemoglobin and total protein rates and cell culture performance.

Origin: South America

The serum is collected or imported and treated in agreement with the European regulations.
