Learn how to verify research-grade peptide purity using HPLC, mass spectrometry, and Certificates of Analysis, plus the key ...

Christie G. Enke and Richard A. Yost didn’t set out to make a mass spectrometer. Their goal was to completely computerize an analytical instrument. It was 1975, still the early days of teaming up ...

The process of protein identification typically begins with a bottom-up approach, where proteins are enzymatically digested—most commonly with trypsin—into smaller peptides. These peptides are ...

When ion mobility spectrometry (IMS) and mass spectrometry (MS) were first combined in a commercial instrument more than a decade ago, users had limited options. If they wanted the analytical power ...
