Laboratory Reconstitution Reference

A step-by-step reference for reconstituting and storing lyophilized research peptides.

Lyophilized (freeze-dried) research peptides require reconstitution with bacteriostatic water before use in laboratory settings. This reference covers the materials required, the reconstitution procedure, and proper storage conditions.

What you will need

Your peptide vial (lyophilized powder)
Bacteriostatic water (BAC) — sterile water with 0.9% benzyl alcohol
Sterile syringe
Alcohol wipes for sterilization

Before you begin

Work in a clean area and wipe vial tops with alcohol.
Use a new syringe and needle each time.

Step-by-step reconstitution

Check your ratioReference the BLP Research Reference guide for the correct BAC-to-peptide ratio for your specific compound.
Draw the BAC waterDraw the required amount of BAC into the syringe. Flick the syringe and ensure there are no bubbles.
Inject slowly down the vial wallInject the BAC slowly down the side of the vial to avoid foaming. Never blast it directly onto the powder.
Swirl — do not shakeGently swirl until fully dissolved. Let it sit if needed. Shaking can degrade the peptide.
Equalize the pressureRemove the needle from the top of the syringe by unscrewing it, then pierce the vial to equalize pressure.
Store correctlyStore the reconstituted peptide in the refrigerator between 35–40°F (approximately 2–4°C).

Storage reference

State	Storage
Lyophilized (unreconstituted)	Refrigerator or freezer
Reconstituted	Refrigerator, 35–40°F (2–4°C)

Keep vials away from direct light. Always use a new sterile syringe and needle for each draw.
