Our research and production experience show that the treatment of high quality New Zealand fetal bovine serum with specific activated carbon/dextran process can effectively reduce the levels of many hormones and growth factors, such as estradiol, progesterone, cortisol, testosterone, T3 and T4. Activated carbon/dextran FBS has been shown to reduce steroid levels in receptor studies and estrogen-related studies, while other studies have shown that activated carbon/dextran FBS can be used to minimize serum differences between batches. Our activated carbon/dextran-treated fetal bovine serum is ideal for the study of hormone effects in various systems in vitro, including steroid receptor binding, cell receptor steroid regulation, hormone secretion in various tissues and thyroid hormone function.

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.
