| Description | Storage Buffer: 20mM HEPES-KOH (pH 7.5), 50mM KCl, 5mM DTT and 50% glycerol. Unit Definition: One unit is the amount of enzyme required to inhibit by 50% the activity of 5ng of RNase A at 25°C (This inhibitor activity is determined by its ability to inhibit hydrolysis of cyclic 2', 3'-CMP by RNase A). Quality Control: Nuclease activity was not detected in any of the following cases, as judged from the intact gel electrophoresis: 1. After incubation of 1ug of λ DNA-Hind III fragments with 300 units of enzyme for 24 hours at 37°C 2. After incubation of 1ug of pBR322 DNA with 300 units of enzyme for 24 hours at 37°C 3. Migrates as a single band of 50 kd in SDS-polyacrylamide gel electrophoresis. Note: Enzyme inhibits in a wide pH range, but most strongly at pH 7-8. Requires DTT of at least 1 mM to be active. |
