Fetal Bovine Serum can contain the antibiotic tetracycline free (tet) and researchers using very sensitive tet-inducible gene expression systems encounter problems with unintended expression as a result. Serum containing minimal levels of tetracycline is needed to ensure accurate gene expression.

Gamma irradiation is an effective means for inactivating the broadest range of viruses and mycoplasmas in fetal bovine serum.However, ionizing radiation may also damage essential growth factors in serum, so one might expect treated Sera to exhibit reduced performance in cell culture.

Charcoal Stripped Fetal Bovine Serum stabilized hormone levels, which helps eliminate some of the influences steroids and other components have on cells.It can be used but not limited to growth assay using over cells.

The Dialyze Fetal Bovine Serum manufacturing process is carefully designed to significantly reduce the concentrations of small molecules such as amino acids, hormones and cytokines while avoiding the precipitation of serum proteins. The dialyzed serum is recommended for special studies .

Ultra low IgG fetal bovine serum has been chromatographically “purified” of IgG, an important factor in isolating organisms that may be inhibited by pre-existing levels of IgG or quantitative IgG immunoassays.

Our exosome-depleted FBS has the highest level of exosome depletion compared to homebrewed material and competitor FBS while retaining the vital nutrients necessary for cell culture. We removed the inefficiency that comes with ultracentrifugation and put the emphasis on a system the removed bovine exosomes
