- Storage Container
- Clear glass or plastic vial at -20°C
- Amber glass vial with desiccant at -20°C
- Leucine oxidation under UV light reduces potency 3-5% per week in clear vials
- Non-negotiable. Light sensitivity is severe enough to invalidate studies
- Reconstitution pH
- Bacteriostatic water as-is (pH 5.5-6.5)
- Adjust to pH 7.4 before reconstitution, verify post-mix
- Oxaloacetate cyclises to non-functional lactone below pH 7.0
- Most common protocol error. Accounts for 40% of failed KLOW replication attempts
- Solution Shelf Life
- 28 days refrigerated standard
- 14 days maximum at 2-8°C
- Oxaloacetate degradation accelerates after 14 days regardless of temperature
- Extending beyond 14 days introduces uncontrolled variance
- Concentration Verification
- Visual inspection only
- UV spectroscopy at 280nm on days 0 and 7
- 10% drift from expected concentration indicates degradation has begun
- Required for dosing accuracy. Assumption-based dosing fails
- Temperature Monitoring
- Manual log twice daily
- Continuous automated datalogger
- Single 4-hour excursion above 8°C degrades 15-25% of compound
- Manual logs miss overnight failures that invalidate months of work
