Sodium pyruvate (Cat. No. 11360070) is supplied as a liquid supplement for cell culture media at 100 mM (100X) and a final concentration of 11,004 mg/L.
Sodium pyruvate serves as an additional energy source for cells in culture. It is often added to low-glucose formulations (1.0 g/L glucose) and is sometimes added to higher-glucose formulations as well. Cells can become hooked on sodium pyruvate however, and if it is withdrawn suddenly from the media, they may experience a short lag in growth.
