The high-quality fetal bovine serum collected from New Zealand will be further processed to obtain this series of products. 

Fetal Bovine Serum (FBS), Exosome Depleted is developed with a method to eliminate exosomes efficiently and in a gentle manner. As fetal bovine serum naturally contains a huge amount of exosomes, there is potential risk of interference with the exosomes secreted by the cells - a highly critical problem in exosome research. In comparison with non-depleted FBS, the cell culture performance of Fetal Bovine Serum (FBS), Exosome Depleted is still outstanding. Therefore, FBS Exosome Depleted is highly suitable for exosome secretion research and cell-cell communication studies.

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.
