What Are Peptides?
Peptides are short chains of amino acids the same building blocks that form proteins linked together by peptide bonds. Whereas proteins typically consist of 50 or more amino acids, peptides generally range from 2 to 50 amino acids in length, giving them distinct physical and chemical properties that make them valuable subjects in biochemical research.
In biological systems, peptides function as signalling molecules, hormones, neurotransmitters, and structural components. Their relatively small size, compared to full proteins, makes them easier to synthesise with high precision and purity in a laboratory setting. This is why research-grade synthetic peptides have become central to many areas of modern biochemical, molecular, and physiological research.
Amino Acid Chains
Peptides are formed by amino acids linked via peptide bonds. The sequence of amino acids determines their three-dimensional structure and biological activity in research models.
Synthetic Synthesis
Research peptides are synthesised using solid-phase peptide synthesis (SPPS), allowing precise control over sequence and enabling high-purity production at research scale.
Lyophilised Form
Auswide Peptides supplies all products as lyophilised (freeze-dried) powder, which maximises shelf stability and maintains molecular integrity during transport and storage.
Research Applications
Synthetic peptides are used across cell biology, biochemistry, pharmacology, and molecular research. Their well-defined structure enables reproducible experimental outcomes.

Reconstitution Guide
All Auswide Peptides products are supplied as lyophilised (freeze-dried) powder and must be reconstituted before use in research applications. Proper reconstitution technique is critical to maintaining peptide integrity and achieving consistent experimental results.Peptides are short chains of amino acids the same building blocks that form proteins linked together by peptide bonds.

Step 1 — Prepare Your Environment
Work under sterile conditions. Use a laminar flow hood or equivalent clean environment. Ensure all equipment — syringes, vials, and surfaces — is sterile before beginning. Wash hands thoroughly and wear appropriate PPE including gloves and eye protection.
Step 2 — Select Your Solvent
Bacteriostatic water (BAC water) is the standard reconstitution solvent for most research peptides, providing a sterile, multi-use solution. Sterile water for injection or 0.9% saline may also be appropriate depending on your specific research protocol and the peptide's solubility characteristics.
Step 3 — Add Solvent Slowly
Draw the appropriate volume of solvent into a sterile syringe. Insert the needle into the peptide vial at an angle, allowing the solvent to run down the inside wall of the vial rather than directly onto the lyophilised powder. This reduces mechanical stress on the peptide structure during dissolution.
Step 4 — Gentle Mixing Only
Once solvent has been added, gently roll or swirl the vial between your palms until the powder is fully dissolved. Do not shake, vortex, or sonicate the vial — aggressive agitation can cause peptide degradation through mechanical shear and may result in aggregation or denaturation.
Step 5 — Verify & Document
Visually inspect the reconstituted solution for clarity — it should appear clear and colourless or very slightly yellow depending on the peptide. Record the reconstitution date, solvent volume, and concentration in your research log. Refrigerate immediately after preparation if not used at once.
Storage Requirements
Correct storage is critical to preserving peptide integrity between receipt and use in research. Lyophilised peptides are stable under the right conditions; however, improper storage can cause degradation, aggregation, or loss of activity that compromises research outcomes.
Lyophilised Powder Short-Term Storage
Lyophilised Powder Long-Term Storage
Reconstituted Solution Long-Term Storage
Protect from Light
Store all peptide vials in a light-protected environment. Amber vials or opaque storage boxes help prevent UV-induced degradation. Never leave vials exposed to direct sunlight or fluorescent lab lighting for extended periods.
Avoid Freeze-Thaw Cycles
Repeated freezing and thawing of reconstituted peptide solutions significantly reduces their stability and can cause aggregation. Aliquot into single-use volumes before freezing to avoid repeated thaw cycles.
Safe Handling
Research peptides should be handled with the same standard laboratory precautions applicable to any biological research material. Although many synthetic peptides have low acute toxicity profiles, they are potent biological signalling molecules and must be treated accordingly in a research context.
Personal Protective Equipment
Always wear nitrile gloves, safety glasses, and a laboratory coat when handling peptide vials and solutions. Minimise skin and eye contact with all research materials.
Sharp Instrument Safety
Use appropriate sharps disposal containers for all needles and syringes used in reconstitution. Never recap needles by hand. Follow institutional sharps disposal protocols at all times.
Containment & Disposal
Dispose of all peptide materials, solutions, and contaminated equipment in accordance with your institution's chemical and biological waste disposal policies. Do not pour solutions down the sink.
Record Keeping
Maintain a detailed research log documenting receipt dates, batch numbers, reconstitution records, storage conditions, and usage. Good documentation practice is essential for reproducibility and compliance.
Documentation & Certificate of Analysis
Every Auswide Peptides order ships with a batch-specific Certificate of Analysis (CoA) generated from independent third-party laboratory testing. Understanding what your CoA contains and how to use it is an important part of maintaining research integrity.
Identity Confirmation
The CoA confirms the peptide identity via HPLC analysis, verifying that the product matches its stated amino acid sequence and molecular weight specification.
Purity Percentage
Purity is expressed as a percentage by HPLC area. All Auswide Peptides products are guaranteed to a minimum of 99% purity. The CoA states the exact figure for that specific batch.
Peptide Content
Measured peptide content (net peptide percentage) accounts for residual water, counterions, and other non-peptide components. This figure is important for accurately calculating molar concentrations in research applications.
Batch Traceability
Each CoA carries a unique batch number that links the product you receive to its specific production run and the laboratory that tested it. This enables full traceability for your research records.

Frequently Asked Questions
What does "lyophilised powder" mean, and why is it supplied this way?
Lyophilisation (freeze-drying) removes water from the peptide under vacuum at low temperature, leaving a stable powder. This form significantly extends shelf life compared to a liquid solution, maintains molecular integrity during shipping, and is easier to store at refrigeration or freezer temperatures without degradation. It is the internationally accepted standard format for research-grade peptide supply.Drawings, dimensions, profile photos or samples, material requirements, finish direction, quantities, project location, timeline, and whether the request is fabrication only or part of a larger installed scope. The more complete the package, the more accurate the review.
How long are peptides stable after reconstitution?
Stability after reconstitution varies by peptide. As a general guide, reconstituted solutions in bacteriostatic water stored at 2–8°C are typically stable for 4–8 weeks. For longer storage, aliquot into single-use volumes and store at −80°C. Always refer to the product-specific data sheet and minimise freeze-thaw cycles.
What is bacteriostatic water and where can I source it?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth and allows the solution to be used multiple times from the same vial. It is the preferred reconstitution solvent for most research peptides. It can be sourced from laboratory supply companies or medical supply distributors. Sterile water for injection is an alternative for single-use applications.
Does my order come with a Certificate of Analysis?
Yes. Every order from Auswide Peptides is dispatched with a batch-specific Certificate of Analysis from an independent third-party laboratory. The CoA covers identity (HPLC), purity percentage, peptide content, water content, and physical appearance. The document is emailed to you on dispatch and can also be accessed via the batch number on our website.
Can I purchase if I am outside Australia?
Currently Auswide Peptides ships within Australia only. International orders are not accepted at this time. If you are based internationally, we recommend checking your local jurisdiction’s regulations on research peptide import before pursuing alternate suppliers.
How are orders packaged for transit?
All orders are packed in discrete, plain outer packaging. Vials are secured with protective foam or bubble wrap inserts to prevent breakage in transit. Lyophilised peptides are stable at ambient temperatures for short periods, but we recommend refrigerating promptly on receipt to maintain optimal condition.
