Sodium pyruvate is commonly added to cell culture media as a carbon source in addition to glucose. Since cells make sodium pyruvate as an intermediate metabolite in the glycolysis pathway, it is not a required supplement for all cell cultures. However, if cells have been grown in medium that is supplemented with sodium pyruvate, we recommend continuing use of the supplement as cell growth may lag without it. Gibco Sodium Pyruvate (100 mM) is formulated using 11 g per liter of water. The final concentration of sodium pyruvate used in most cell culture media is 1 mM.
cGMP Manufacturing and Quality System
For supply chain continuity, we manufacture Gibco Sodium Pyruvate (100 mM) at two separate facilities located in Grand Island, NY and Scotland, UK. Both sites are compliant with cGMP manufacturing requirements and are certified to the ISO 13485 standard.
