Reconstitution Steps
- Draw 3.0 mL bacteriostatic water using a sterile syringe for the main concentration reference shown below.
- Slowly add the BAC water down the side of the vial wall.
- Gently roll or swirl the vial until the material is completely dissolved. The solution may appear clear to blue-tinted depending on supplier format, copper complex form, and concentration. Do not shake!
- Because this is a higher-concentration copper-peptide preparation, verify complete dissolution before recording the final preparation details.
- Label with compound name, vial amount, concentration, solvent volume, preparation date, storage conditions, and handling notes.
- Store refrigerated at 2–8°C / 35.6–46.4°F, protected from direct light.
