Worthington Biochemical FAQ

Is ribonuclease A (RAF, filtered) still stable after being stored at -20°C (product says to store at 2-8)?

Ribonuclease A can be stored frozen at -20°C. We store lyophilized ribonuclease A (code RAF) at 2-8°C and it is stable for at least two years. Storing ribonuclease A at -20°C will not harm the enzyme.
