Solution stability storage period determination

Once the solution stability has been determined, a storage period should be determined based on the use of the method under real-world conditions. Data may show a standard solution to be very stable for 6 months at room temperature, but a quality control (QC) lab may not want to use this solution for such a long time. 

The stability of parathion hydrolase was determined for refrigerator storage and room temperature storage. The enzyme solution is stable under refrigeration ( ) The enzyme also remains stable at room temperature for long periods ( ).
