Improved Media For The Expression Of Recombinant Vitamin K-Dependent Proteins

Patent No. EP3383894 (titled "Improved Media For The Expression Of Recombinant Vitamin K-Dependent Proteins") was filed by CSL Behring Lengnau on Dec 2, 2016. The application was issued on May 6, 2020.

Patent Summary

Enhancing the activity of recombinant vitamin K-dependent proteins like factors VII and IX by adding specific compounds to the cell culture media during expression. The compounds are TCA cycle intermediates like alpha-ketoglutaric acid, succinic acid, oxaloacetic acid, malic acid, fumaric acid, and citric acid, as well as the antioxidant glutathione. These compounds provide additional reductive potential to maintain the proper redox environment for vitamin K-dependent protein carboxylation.
