Peptide Stability: What Degrades Your Research Compounds and How to Prevent It
You sourced the peptide correctly. You reconstituted it properly. You stored it at the right temperature. And yet, six weeks later, your results are inconsistent — or worse, absent. What went wrong? The answer is almost always peptide degradation. Even under seemingly ideal conditions, research-grade peptides are vulnerable to a range of environmental stressors that silently erode their integrity. Understanding the mechanisms of degradation — and the strategies to prevent them — is essential for any researcher working with these compounds. Why Peptide Stability Matters Peptides are short chains of... Read more...
