About Our Peptides

What exactly are research peptides?

Research peptides are synthetic chains of amino acids supplied as reference materials for laboratory experiments. Aūra Peptides products are intended strictly for controlled research use and are not manufactured, packaged, or sold for human or veterinary use.

In what form will I receive my peptides?

Most Aūra Peptides are supplied as lyophilized (freeze-dried) powder in sealed glass vials. When a peptide is offered in pre-made solution, that form will be clearly indicated on the product page and vial label.

What purity level do your peptides have?

Unless otherwise noted, our research peptides are typically ≥98% purity by analytical HPLC. Exact purity and analytical methods for each batch are documented on the corresponding Certificate of Analysis (COA).

Can I access Certificates of Analysis (COAs)?

Yes. Every peptide batch is released with a COA summarizing purity, identity confirmation methods, lot number, and other key analytical data. COAs are available digitally or upon request from our support team.

How should I store peptides before reconstitution?

Many laboratories store sealed, lyophilized vials in a dark, dry environment at −20 °C for long-term stability. For short-term use, some labs hold vials at 2–8 °C (refrigerated). Always follow your own validated institutional or lab-specific storage procedures.

How should I store peptides after reconstitution?

Reconstituted solutions are generally less stable than lyophilized material. Many labs aliquot solutions to minimize freeze–thaw cycles and store them at 2–8 °C for short-term use or at sub-zero temperatures for longer-term work. Stability should be confirmed within your own assay system.

Is it okay to freeze reconstituted peptides?

Many laboratories freeze aliquots of reconstituted peptides at −20 °C or below. Sensitivity to freezing and repeated freeze–thaw cycles can vary by sequence, so best practices should be defined by your internal protocols and validation data.

How much solvent should I use when reconstituting a vial?

Each vial label lists the total peptide content (for example, 5 mg or 10 mg). To determine solvent volume, choose your target concentration for the experiment and calculate the volume based on the mass in the vial. Solvent choice and final concentration should follow your lab’s protocol.

What’s the correct way to reconstitute peptides?

A common approach is to add an appropriate sterile solvent (such as bacteriostatic water or another lab-approved vehicle) slowly down the wall of the vial, then gently swirl or invert until fully dissolved. Avoid vigorous shaking or frothing, and always follow your institution’s SOPs for handling reference materials.

How will I know when a peptide should be discarded?

Labs typically define discard timelines based on internal stability data, storage conditions, and visual inspection (for example, cloudiness or unexpected precipitation). Any peptide that appears compromised, has been stored outside recommended conditions, or falls outside your validated window should be discarded according to your lab’s safety procedures.

Are your peptides intended for personal or clinical use?

No. All Aūra Peptides products are supplied strictly as research-only reference materials. They are not intended for personal, medical, or veterinary use, and should only be handled by qualified individuals in appropriate laboratory environments.
