- Direct injection onto powder
- Bacteriostatic water
- Fast injection directly onto peptide at vial bottom
- 7–14 days (reduced due to mechanical denaturation)
- Moderate (foaming increases surface area for contamination)
- Not recommended. Mechanical shear from direct impact causes immediate partial denaturation and reduces bioactivity
- Wall-directed slow injection
- Slow injection (10–15 sec/mL) down vial wall at an angle
- 28 days when refrigerated at 2–8°C
- Low (minimal agitation, proper aseptic technique)
- Gold standard. Preserves tertiary structure, minimizes foaming, maximizes solution stability
- Sterile water reconstitution
- Sterile water (no preservative)
- Single use only (bacterial growth begins within 48 hours)
- High (no bacteriostatic agent)
- Only acceptable for immediate single-dose use. Never for multi-dose vials or protocols requiring storage
- Saline reconstitution
- 0.9% sodium chloride
- Variable (salt may cause precipitation at higher peptide concentrations)
- Moderate
- Avoid. Sodium chloride increases ionic strength, which can destabilize SNAP-8 and cause aggregation above 1.5mg/mL
