How to read a certificate of analysis
A certificate of analysis identifies the product and lot, the tests performed and the results. Our guide on how to read a COA for research peptides walks through each section of a typical report and what to check before you start an experiment.
Handling after delivery
Purity at the time of testing is only part of the picture; storage and handling in the laboratory matter too. Our peptide storage and stability guide covers storage of lyophilized and reconstituted peptides. For reconstitution, we stock Hospira Bacteriostatic Water 30mL.
