Technical guides
How to read a peptide COA: identity, purity and batchA guide to reading a certificate of analysis (COA): what HPLC and mass spectrometry measure, what a purity percentage means and how to check a report is genuine.Read →HPLC vs LC-MS for peptides: what each technique measuresDifferences between HPLC (purity) and LC-MS (identity) applied to peptides, how to read a chromatogram and the limitations of each method.Read →What “Research Use Only” (RUO) means for buyersWhat an RUO product is, what it means for the buyer, why product information must be consistent and what documentation to expect from a supplier.Read →Storage and handling of lyophilised peptides in the laboratoryGood laboratory practice for storing and handling lyophilised peptides: temperature, moisture, light, freeze–thaw cycles and batch records.Read →
