One of the primary reasons peptides are commonly supplied in lyophilized, or freeze-dried, form is stability. Removing most of the water from a peptide formulation can dramatically slow many of the chemical reactions that contribute to degradation. But lyophilization does not make a peptide indestructible. Temperature, moisture, oxygen, light, packaging, repeated temperature changes, and the […]

When purchasing or evaluating research peptides, you will frequently encounter the term COA, or Certificate of Analysis. It is one of the most important documents associated with a peptide—but it is also one of the most commonly misunderstood. A Certificate of Analysis is essentially a laboratory report describing a particular sample or batch and the […]

Peptides are short chains of amino acids that participate in an enormous range of biological processes. As peptide science has advanced, researchers and pharmaceutical developers have faced an important question: What is the best way to deliver a peptide to its intended destination? Unlike many conventional small-molecule compounds, peptides can be relatively large, water-soluble molecules […]

Peptides have become an increasingly important area of scientific research, appearing in studies involving metabolism, cellular signaling, tissue repair, immune function, aging, neurological processes, and many other biological systems. However, peptides present researchers and manufacturers with an important challenge: stability. Many peptides are relatively delicate molecules. When maintained in a liquid solution for extended periods, […]
