Quality Criteria for KPV
When purchasing KPV for research, verify these essential criteria:
1. Certificate of Analysis (CoA)
A valid CoA should include:
- HPLC purity: minimum 98%
- Mass spectrometry: confirmation of molecular weight (357.45 g/mol)
- Endotoxin testing: particularly important for research
- Traceable batch number
2. Storage Conditions
- Lyophilized powder: stable at -20°C for several years
- After reconstitution: 4°C, use within 2-4 weeks
- Capsules: room temperature, protected from light
3. Molecular Structure
Authentic KPV is a tripeptide with the sequence Lys-Pro-Val, derived from amino acids 11-13 of alpha-MSH. Verify the supplier confirms this structure.
