- Direct injection onto powder
- Needle aimed at lyophilised powder, fast plunger depression
- High. Creates foam and mechanical shear stress that disrupts protein folding
- 2–3 minutes with agitation
- Not recommended. Visible foaming indicates protein damage has already occurred
- Down-the-wall injection, swirling
- Needle angled against vial wall, slow injection, gentle swirling motion after
- Low. Minimises mechanical stress, allows controlled hydration
- 5–10 minutes with periodic swirling
- Standard research protocol. Preserves peptide integrity while ensuring complete dissolution
- Down-the-wall injection, passive dissolution
- Needle angled against vial wall, slow injection, no agitation. Left to dissolve naturally
- Lowest. Zero mechanical stress, gravity and diffusion do the work
- 15–30 minutes depending on peptide mass
- Safest method but impractical for time-sensitive workflows
- Vigorous shaking after injection
- Any injection method followed by rapid shaking
- Very high. Shearing forces denature protein bonds even faster than direct injection
- Under 1 minute
- Never acceptable. Speed is not worth total loss of biological activity
