Frequently Asked Questions About Peptide Testing

Common questions about our peptide analysis and verification services

What types of peptides can you test?

Our testing capabilities cover 103 peptides. Contact our team to confirm the appropriate analytical methods and sample requirements for your research peptides.

How long does peptide testing take?

Turnaround is 5–7 business days for eligible routine testing from sample receipt. Complex testing panels or custom protocols may require additional time. Contact our team to confirm eligibility and timing for your samples.

What analytical methods do you use for peptide testing?

Our peptide testing laboratory utilizes High-Performance Liquid Chromatography (HPLC), Liquid Chromatography-Mass Spectrometry (LC-MS), ESI-MS, and other advanced analytical techniques to ensure accurate peptide characterization and purity determination.

How much sample is required for peptide testing?

Minimum sample requirements vary by test type. For basic purity testing, we typically need 1-5mg of peptide. For comprehensive analysis including molecular weight verification and contaminant testing, we recommend 5-10mg. Contact us for specific requirements for your peptide testing needs.

What information is included in the peptide analysis report?

Our Certificate of Analysis includes peptide purity percentage, molecular weight confirmation, HPLC chromatogram, mass spectrometry data, identification of impurities, testing methodology details, and expert interpretation. All reports are reviewed and signed by our PhD-level scientists.

Do you offer peptide testing for regulatory compliance?

Yes, we provide GMP-compliant peptide testing services suitable for regulatory submissions. Our testing protocols follow FDA guidelines and ICH standards for pharmaceutical peptide analysis. We can customize testing to meet specific regulatory requirements for your peptide products.

How do I ship my peptide samples to your laboratory?

Peptide samples should be shipped frozen with dry ice or at room temperature for stable peptides. We provide detailed shipping instructions and accept samples via FedEx, UPS, or other major carriers. For temperature-sensitive peptides, overnight shipping with appropriate cold packs or dry ice is recommended.
