- Cold-Chain Temperature Monitoring
- Recorded once daily at check-in; gaps of 16+ hours between readings
- Continuous logging with alerts for excursions >10 minutes above threshold
- Automated logger with SMS alerts at −18°C (frozen) / 10°C (refrigerated). Timestamped to the minute
- Manual logging misses the 4–8 hour temperature spikes that cause partial denaturation without visible changes. Automated systems catch them in real time
- Reconstitution Protocol
- 'Reconstituted with 2mL bacteriostatic water on [date]'
- Full protocol: exact volume, water lot number, benzyl alcohol %, technique (swirl vs vortex), reconstitution timestamp to the hour
- Standardised template requiring 8 data fields including post-reconstitution UV absorbance verification
- Generic logging can't identify whether result variance came from concentration error, technique variance, or stability window miscalculation
- Dosing Administration Log
- Animal ID, dose volume, date
- Animal ID, dose volume, timestamp, injection site, needle gauge, technician initials, vial temperature at draw
- Full dosing log + pre-injection vial temperature check + post-injection remaining volume verification
- Without technician accountability and temperature verification at draw, you can't distinguish administration error from peptide degradation
- Contamination Tracking
- Batch number recorded at study start
- Batch number, synthesis date, COA, moisture content at receipt, endotoxin level
- Batch-level traceability with side-by-side COA comparison across all vials used in study + moisture testing at receipt
- If one animal shows anomalous results, batch traceability lets you correlate it with manufacturing variance rather than assuming experimental error
