Reconstituting a lyophilized research peptide means dissolving the powder in bacteriostatic water so a precise volume can be drawn for research. Here is the standard laboratory procedure, plus a calculator to work out concentration and draw volume.
What you need
- Your lyophilized peptide vial
- Bacteriostatic water (0.9% benzyl alcohol)
- A sterile syringe
- Alcohol swabs
Step by step
- Swab both vial stoppers with alcohol and let dry.
- Draw your calculated volume of bacteriostatic water into the syringe.
- Inject the water slowly, letting it run down the inside wall of the vial — never spray it directly onto the powder.
- Swirl gently to dissolve. Do not shake — agitation can damage the peptide.
- Once clear, store refrigerated and protected from light.
