Peptide Reconstitution Kit

Why a kit

Reconstitution is the step where a dry, lyophilized peptide is dissolved into a solution of defined concentration. It is simple in principle, but doing it reproducibly and without contaminating the vial depends on having the right consumables to hand: a preserved diluent, a sterile syringe that measures small volumes accurately, and a swab to disinfect stoppers. The starter kit collects those three items so that a laboratory's first peptide order arrives with everything required to prepare it.

Component roles

• Bacteriostatic water — the solvent. The 0.9% benzyl alcohol preservative inhibits bacterial growth, which matters because both the water vial and the reconstituted peptide vial are entered repeatedly during a study.
• 31G × 1 mL insulin syringes — the measuring device. Fixed fine-gauge needles minimize stopper coring and dead space, and 0.01 mL graduations allow the diluent volume, and therefore the final concentration, to be set precisely.
• Alcohol prep pads — the aseptic step. Wiping the stopper of both the water vial and the peptide vial before every puncture is standard aseptic technique.

Basic reconstitution workflow

What the kit does not include

The kit does not include the peptide itself, sterile empty vials for aliquoting, or a sharps container. Laboratories preparing many vials, splitting stock into working aliquots, or generating a large number of used needles should add those items; they are listed as related products.

Store the sealed kit at room temperature away from light and moisture. Keep syringes and prep pads in their individual wrappers until the moment of use and discard any syringe whose wrapper is open or damaged. When preparing a vial, work on a clean surface, swab every stopper with a prep pad and let it dry, and use a new syringe for each transfer. After the bacteriostatic water vial has been punctured for the first time, mark the date on the label and store it refrigerated. Used syringes go directly into a sharps container; do not recap by hand.
