Laboratory Guides for Research Peptides

How research peptides are made, stored and tested — written as laboratory reference material, with sources cited and the limits of the evidence stated. For testing and certificate-of-analysis topics, see our testing standards; for compound-by-compound reading, see the research overviews and comparisons.

• Storing Lyophilized Research Peptides: What Suppliers StateWhat peptide suppliers state about storing lyophilized powders: temperature, moisture, light, freeze-thaw and sequence, and where their pages differ.
• How Research Peptides Are Made: From Resin to Lyophilized PowderHow synthetic research peptides are made: solid-phase synthesis, cleavage, RP-HPLC purification and lyophilization, and what each step means for a COA.
