The high-quality fetal bovine serum collected from New Zealand will be further processed to obtain this series of products. Fetal Bovine Serum (FBS), Delipidated is used for applications, where a reduced lipid concentration in FBS is required, such as lipid metabolism studies or arteriosclerosis research.

Fetal Bovine Serum (FBS), Delipidated is produced using the fumed silica precipitation method. When fumed silica is added to serum, non-polar substances, such as lipids and steroids, adsorb to the surface of the silica. The solution is then centrifuged and the pellet of fumed silica with adsorbed lipids is removed. The serum is then sterile-filtered. The acceptance criterion for the treatment is a level of cholesterol lower than 10 mg/100 ml. Lipids and other non-polar substances are reduced in comparison to non-treated serum.

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.
