Understanding Peptide Purity: What Percentages Mean in a Research Context
Ninety-eight percent pure. It sounds reassuring, like a number close enough to perfect that the remaining two percent is barely worth thinking about. In some […]
How to Read a Certificate of Analysis for Research Peptides
When a research peptide arrives from a supplier, it comes with a document that most people glance at briefly before setting aside. That is a […]
What Are the Differences Between Peptide Grades Used in Research?
Not every research application demands the same thing from a peptide, and not every peptide needs to be produced under the same manufacturing standards to […]
A Glossary of Terms Used in Peptide Research and Procurement
Every specialized field develops its own vocabulary, and peptide research is no exception. The terminology that appears in scientific literature, supplier catalogs, certificates of analysis, […]
Mass Spectrometry in Peptide Verification: A Plain-English Explanation
If HPLC answers the question of how pure a peptide is, mass spectrometry answers a different and equally important question: is this compound actually what […]
Lyophilized vs. Liquid Peptides: What Researchers Should Know
Walk through the catalog of any research peptide supplier and you will find that the overwhelming majority of compounds are offered in lyophilized form. A […]
What Is HPLC Testing and Why Does It Matter for Peptide Quality?
The purity percentage that appears on every research peptide certificate of analysis comes from one specific analytical technique: high-performance liquid chromatography, almost universally abbreviated as […]
How to Store Research Peptides Properly
A research peptide is only as good as the conditions it has been kept in. This is not an abstract concern. Peptides are chemically active […]
How to Reconstitute a Lyophilized Peptide for Research Use
Reconstitution is the step that stands between a lyophilized research peptide and a usable research solution, and it is a step that is easy to […]
What to Look for When Evaluating a Peptide Supplier
The research peptide market is not uniformly regulated, and the quality of compounds available from different suppliers varies considerably. Some suppliers operate with rigorous manufacturing […]
