Recent Developments in Column Technologies for the Analysis of Proteins and Peptides
Special Issues
Column developments in HPLC have benefited protein aqnd peptide separations in a number of ways. More silica based phases and column formats have become available, expanding the use of HPLC for the separation of proteins by different modes of chromatography as well as improving resolution and throughput. Hydrophobic interaction chromatography, immobilized metal affinity chromatography as well as ion Exchange and size exclusion are now practical analytical tools for proteins and peptides. New enrichment columns are benefiting proteomic research.
USP CEO Discusses Quality and Partnership in Pharma
December 11th 2024Ronald Piervincenzi, chief executive officer of the United States Pharmacoepia, focused on how collaboration and component quality can improve worldwide pharmaceutical production standards during a lecture at the Eastern Analytical Symposium (EAS) last month.
Measuring Tooth Discoloration from Coffee with HPLC
December 11th 2024Researchers measured bovine tooth enamel samples with colorimetry, high-performance liquid chromatography (HPLC), and ultraviolet-visible (UV-Vis) spectrophotometry to develop a comprehensive understanding of coffee-induced tooth discoloration by examining the individual and combined effects of CGA and pigments and determining how their concentrations are affected by coffee roast level.
