Summary
1. The inactivation of crystalline ribonuclease by formaldehyde and formaldehyde containing fixatives (Serra's solution) is demonstrated.
2. The rate of inactivation is shown to be dependent uponph, formaldehyde concentration, and time of action of the fixative.
3. The effect of formaldehyde containing fixatives on the RNase activity in sections from fixed tissues is discussed, and the inactivation of that enzyme system in rat pancreas is demonstrated.
