Reconstituting | Storage

This page provides general information on the handling, reconstitution, and storage of research peptides. The guidance below is intended to support laboratory best practice, peptide stability, and appropriate storage conditions when working with peptide-based research materials.

Information is provided for educational and reference purposes only and should always be used alongside established laboratory protocols and regulatory requirements.

Reconstituting Lyophilised Peptides

Research peptides are commonly supplied in a lyophilised (freeze-dried) form to enhance stability during storage and transport.

Reconstitution involves adding a suitable sterile diluent (such as bacteriostatic or sterile water) to return the peptide to a liquid state for laboratory handling.

  • Handle peptides in a clean, controlled environment
  • Use sterile syringes, needles, and equipment
  • Add diluent slowly down the inside wall of the vial
  • Do not shake; gently swirl or roll if mixing is required
  • Allow time for the peptide to fully dissolve

The volume of diluent required will depend on the specific peptide, desired concentration, and research protocol.

Peptide Storage Guidelines

Lyophilised (Unreconstituted) Peptides

  • Store in a cool, dry place
  • Recommended storage temperature: 2–8°C
  • Protect from light, heat, and moisture
  • Keep vials sealed until reconstitution

Reconstituted Peptides

  • Store refrigerated at 2–8°C
  • Avoid repeated warming and cooling cycles
  • Keep vials sealed when not in use
  • Do not freeze unless required by a specific research protocol
Handling & Stability Information
  • Clearly label vials with, concentration, and reconstitution date
  • Do not use solutions that appear cloudy, discoloured, or contain particulates
  • Peptide stability varies depending on formulation and sequence
  • Always follow internal laboratory or research protocols
Peptide FAQ

What does lyophilised mean?
Lyophilised peptides are freeze-dried to remove moisture, improving stability and shelf life.

Are liquid peptides more stable?
No. Lyophilised peptides are generally more stable for long-term storage.

Do peptides need refrigeration?
Most research peptides should be stored at 2–8°C.

Can peptides be frozen?
Freezing is not recommended unless required by protocol.

Why should peptides not be shaken?
Shaking may compromise peptide structure.
