Working references on handling, storage and the analytical methods behind the numbers on every certificate. Written for laboratory buyers, not for consumers.
A step-by-step laboratory reference for reconstituting lyophilized research peptides: diluent choice, technique, concentration maths and storage of the prepared solution.
Read the guide →What the HPLC trace, purity percentage, endotoxin figure and mass-spec confirmation on a peptide certificate of analysis actually tell you, and what they do not.
Read the guide →Storage temperatures, light and moisture protection, freeze-thaw damage and shipping considerations for lyophilized research peptides.
Read the guide →How reverse-phase HPLC measures peptide purity, what the percentage represents, what the impurities usually are, and where the method's limits lie.
Read the guide →What bacterial endotoxin is, why it matters in laboratory work, how the Limulus amebocyte lysate assay measures it, and how to read an EU/mg figure.
Read the guide →Plain definitions of the terms used on research peptide certificates, product pages and bench protocols - from acetate salt to lyophilization to tabular purity.
