Tetracycline Negative Fetal Bovine Serum
100-800

Fetal Bovine Serum can contain the antibiotic tetracycline (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.

This product is used in cell culture applications using tet-inducible gene expression systems, and other applications in which the presence of tetracycline would prove disruptive. The limit of detection is approximately 0.001 µg/ml.

Stasis™ Stem Cell Qualified U.S. Origin Fetal Bovine Serum
100-525

Stem cells are the least differentiated of all cell types. Many biomolecules common in sera can trigger unwanted differentiation. As such, these cells have uniquely pristine requirements for growth in culture. Our stem cell qualified fetal bovine serum has been specifically tested for its ability to sustain the undifferentiated cellular morphology of these cells. This quality product comes exclusively from US sources.

AbSolute™ Low IgG Fetal Bovine Serum
100-120

AbSolute™ low-IgG fetal bovine serum is selected from lots with naturally low amounts of IgG. IgG is the major immunoglobulin found in normal animal serum, accounting for 70-75% of the total pool. It is a natural serum component involved in immune function and the only class of immunoglobulins able to cross the placenta. Natural bovine serum IgG can interfere with cell culture studies in which the cells may be producing a specific IgG molecule of interest. Gemini never uses artificial methods to remove IgG from bovine serum, as these treatments may interfere with culture performance.

Charcoal:Dextran Stripped Fetal Bovine Serum
100-119

Gemini offers charcoal:dextran stripped fetal bovine serum for researchers requiring low levels of certain steroid hormones. Charcoal:dextran stripping reduces the serum concentration of many hormones and certain growth factors, such as estradiol, cortisol, corticosterone, the B vitamins,T3, T4 and prostaglandins. Post-strip assay results are reported. This serum is useful where these endogenous molecules may interfere with experimental work. This serum may show some reduced growth-promotion ability for cells requiring the stripped compounds.

Dialyzed Fetal Bovine Serum
100-108

Dialysis removes many small molecules from FBS such as glucose, salts and some non-protein bound serum molecules. This process generally does not remove hormones that are serum bound but it may reduce growth promotion capabilities for some cell types. The dialysis process is done by ultra filtration with a 10,000 molecular weight cut-off membrane. The serum is processed at 4°C with a careful monitoring of pH, osmolality and glucose concentration.

Gamma-Irradiated Fetal Bovine Serum
100-201

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 cullture.
