The high-quality fetal bovine serum collected from New Zealand will be further processed to obtain this series of products. Fetal Bovine Serum (FBS), Tetracycline Negative is widely used in eukaryotic cell culture, typically as a supplement for growth media. Fetal bovine serum contains nutritional and embryonic growth promoting factors that are essential for a successful cell culture. Further, fetal bovine serum contains various small molecules, such as, e.g., amino acids, lipids, sugars, and hormones.

Cell culture applications with tet-inducible gene expression systems and other applications, where the presence of tetracycline would be disturbing, require the use of a tetracycline-negative FBS. Capricorn Scientific has established a test with an external laboratory, using liquid chromatography-tandem mass spectroscopy to detect all kinds of tetracycline. This method allows accurate detection of Chlortetracycline and Oxytetracycline in a range of 0.05 mg/l.

Intended Use

For Further Manufacturing or Research Use Only. Not for Diagnostic or Therapeutic Use. 

Use Instructions

For use in cell culture media, the supplementation ranges from 5% to 20%. The optimum concentration concentration should be determined by the ultimate user. 

Heat Inactivation

Serum may be heat inactivated at 56°C for 30 minutes.  

Storage and Stability

Store at -10°C to-40°C. Product is stable for 5 years from the date of manufacture if kept at frozen temperature. We suggest that the product should not be subjected to multiple freeze-thaw cycles, should be made into aliquots. Turbidity or flocculent material may be observed upon thawing or prolonged storage at refrigerated temperatures. This is normal in most serum products and not detrimental to its performance.
