Sodium Pyruvate, sterilized by 0.22 μm filtration, DNase & RNase free, Protease-free,  Pyrogen-free, is the most common pyruvate salt, also known as sodium metabisate  or sodium 2-carbonylpropionate salt. Its molecular formula is C₃H₃NaO₃ and its  molecular weight is 110.04. Sodium Pyruvate is an intermediate product of glycolysis  and can directly enter and exit cells. It is an essential nutrient for cell metabolism. In  the absence of glucose, it can serve as an energy source for cells and is one of the  commonly used additives in cell culture. Some cells require additional sodium pyruvate  when cultured in vitro. A certain amount of sodium pyruvate can also be added during  clone culture and when reducing serum concentration. Meanwhile, sodium pyruvate  also helps to reduce the phototoxicity caused by fluorescent substances. 

Instructions for use 

Sodium pyruvate solution is prepared with water for injection, sterilized through a 0.1  μm filter, and becomes a 100 mM concentrated solution. It can be diluted as needed  for use. 

Storage conditions: The solution should be stored upon receipt at -20℃ . The product is stable for 24 months.
