What Are Research Peptides?

Research peptides are short chains of amino acids, typically containing between 2 and 50 residues, that are synthesized for use in laboratory and scientific research. Unlike proteins, which fold into complex three-dimensional structures, peptides are smaller molecules that can be precisely engineered to interact with specific biological targets such as receptors, enzymes, and signaling pathways.

These compounds play a critical role in advancing our understanding of human physiology, disease mechanisms, and potential therapeutic targets. Research peptides are used extensively in fields including endocrinology, neuroscience, immunology, oncology, and metabolic research. Their specificity and potency make them invaluable tools for investigating cellular processes at the molecular level.

At AminoCore Research, every peptide we supply undergoes rigorous quality control. Each batch is independently tested using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to confirm identity, purity (≥98%), and molecular weight. A Certificate of Analysis (COA) is included with every order, providing full analytical documentation for your research records.

HPLC Analysis and Quality Assurance at AminoCore Research

Quality Assurance & Analytical Standards

Quality is not negotiable in peptide research. Impurities, degradation products, or incorrect molecular weight can invalidate entire experimental series. AminoCore Research maintains strict quality control procedures to ensure every compound meets the standards your research demands.

Our analytical workflow includes reverse-phase HPLC for purity assessment (minimum ≥98% for all catalog compounds), electrospray ionization mass spectrometry (ESI-MS) for molecular weight confirmation, and amino acid analysis for sequence verification on select compounds. Each batch receives a unique lot number traceable to its synthesis date, purification records, and analytical results.

The Certificate of Analysis (COA) accompanying every shipment includes HPLC chromatograms, MS spectra, purity percentage, appearance, solubility data, and recommended storage conditions. Researchers can request additional documentation or custom purity requirements for specialized protocols.

Peptide Handling & Storage Guidelines

Proper handling is essential to preserve peptide integrity and ensure reliable experimental results.

Long-Term Storage

Store lyophilized peptides at -20°C or below in sealed, desiccated containers. Avoid repeated freeze-thaw cycles. Most peptides maintain stability for 12–24 months when stored properly.

Reconstitution

Reconstitute with sterile bacteriostatic water, PBS, or other appropriate solvents. Allow the vial to reach room temperature before opening. Add solvent gently along the vial wall to avoid foaming.

Shipping & Transit

All orders ship with appropriate cold-chain packaging when required. Lyophilized peptides are stable at ambient temperature during transit for up to 7 days without significant degradation.

Working Solutions

Prepare aliquots to minimize freeze-thaw cycles. Reconstituted solutions should be stored at 2–8°C for short-term use (up to 2 weeks) or at -20°C for extended periods.

Frequently Asked Questions

What purity level do your peptides have?

All peptides in our catalog have a minimum purity of ≥98% as verified by reverse-phase HPLC analysis. Each order includes a Certificate of Analysis (COA) with chromatograms and mass spectrometry data confirming identity and purity.

How should I store research peptides?

Lyophilized (freeze-dried) peptides should be stored at -20°C or below in a sealed container with desiccant. Reconstituted peptides should be aliquoted and stored at -20°C to minimize freeze-thaw cycles. Most lyophilized peptides maintain stability for 12–24 months under proper storage conditions.

Do you provide Certificates of Analysis?

Yes, every order includes a COA specific to your batch lot number. The COA includes HPLC purity data, mass spectrometry results, physical appearance, solubility information, and recommended storage conditions. Additional analytical documentation is available upon request.

What countries do you ship to?

We ship to the United States, Canada, Brazil, Paraguay, Mexico, Germany, Switzerland, United Kingdom, Spain, and Portugal. All international shipments include appropriate documentation and packaging. Delivery times vary by destination.

Are these peptides for human consumption?

No. All products sold by AminoCore Research are strictly for laboratory and in-vitro research use only. They are not intended for human or animal consumption, and are not to be used for diagnostic, therapeutic, or any other clinical purpose.

How do I reconstitute lyophilized peptides?

Allow the vial to reach room temperature before opening. Using a sterile syringe, slowly add bacteriostatic water or the appropriate solvent along the vial wall. Gently swirl (do not shake) until fully dissolved. The specific volume of solvent depends on the desired concentration for your protocol.

For Laboratory Use Only

All compounds are intended strictly for in-vitro research and laboratory testing. Not for human or animal consumption. By placing a request, you confirm you are a qualified researcher or represent a research institution.
