Product Stability
- CSE is reconstituted with LRW or equivalent, and is stored at 2–8°C before and after reconstitution. Once reconstituted, the maximum storage time for the different CSE preparations is 10 ng/vial: 7 days, 0.5 µg/vial: 4 weeks, 125 µg/vial: 3 months. *CSE should not be frozen.
- The reconstituted lysate is stable for 24 hours at 2–8°C or for two weeks at -20°C or colder if frozen immediately after reconstitution. Reconstituted Chromo-LAL lysate may be frozen and thawed once.
- Once reconstituted, Pyrochrome is stable for 8 hours when stored at 2–8ºC.
- Pyrosate is stable at room temperature and does not require refrigeration for shipping or storage.
- The reconstituted lysate is stable for 24 hours at 2–8°C or for up to 3 months at or below -20°C. May be frozen onceand will retain activity for as long as 3 months if stored at or below -20°C.
- Once reconstituted, Pyrotell®-T lysate is stable for 24 hours, if stored at 2–8°C. Pyrotell®-T lysate may be frozen onceand will retain activity for as long as 3 months if stored at or below -20°C.
