Reconstitution Guide

A general overview of the standard laboratory technique for reconstituting a lyophilized peptide with a sterile diluent.

For laboratory research use only. This page describes a general bioscience laboratory technique. It is not medical, veterinary or human-administration guidance. Always follow your institution’s standard operating procedures.

Materials typically used

Sterile diluent

Bacteriostatic or sterile water, per your protocol.

Syringe

Appropriately sized sterile syringe.

Alcohol swabs

For sanitizing vial stoppers.

Lyophilized vial

The peptide vial to be reconstituted.

1

Sanitize

Wipe the vial stopper with an alcohol swab and allow it to dry.

2

Add diluent slowly

Inject the diluent slowly down the inside wall of the vial rather than directly onto the powder.

3

Swirl, don’t shake

Gently swirl the vial to encourage dissolution — vigorous shaking can degrade the peptide structure.

4

Inspect

Confirm the solution is clear with no visible particulate before use.

5

Label

Label the vial with the date, diluent volume added and resulting concentration.

6

Store correctly

Follow Peptide Storage & Handling guidance for the reconstituted solution.

Do the math

Work out your reconstitution concentration

Use the calculator to determine diluent volume or resulting concentration.
