  • Peptide Supplier Documentation Checklist for RUO Labs

    This article explains how to build a peptide supplier documentation checklist for research-use-only procurement. It shows what qualified labs should verify on batch-specific COAs, labels, SDSs, analytical methods, and storage records before a peptide lot enters a study workflow.

  • Peptide Testing Methods: HPLC vs LC-MS vs NMR

    Peptide testing methods such as high-performance liquid chromatography (HPLC), liquid chromatography–mass spectrometry (LC–MS), and nuclear magnetic resonance (NMR) spectroscopy are essential analytical tools for characterizing research-grade peptides. Each technique provides different information: HPLC assesses purity and impurity profile, LC–MS confirms molecular weight and sequence, and NMR reveals structural details. This article reviews how HPLC, LC–MS,…

  • Peptide Solubility as a Research Documentation Topic

    Peptide solubility documentation helps researchers interpret lot-specific records, analytical methods, and condition variables without turning solubility notes into product-use guidance.

  • Peptide Storage Checklist for RUO Materials – Best Practices and Guidelines

    Peptide storage checklist for RUO materials – guidelines for researchers on maintaining peptide stability, including temperature, light, and handling precautions.

  • Peptide Sequence Basics for Research Buyers

    This article explains how research buyers should read peptide sequence notation, connect it to identity testing, and review batch-specific documentation. It is written for laboratory procurement audiences and framed strictly for research-use-only evaluation.
