In our new podcast series, we're joined by a Bioanalysis author to review their publication's biggest challenges, wider implications and next steps. In episode four, we're joined by Senior Scientist and Technical Specialist Ashley Phillips. Ashley's publication assessed the performance of next-generation trypsins for rapid protein LC-MS bioanalysis, effectively reducing a two-day process into just one day's work. As the paper's lead author, Ashley outlines the experimental design, the challenges associated with data storage and how he and the team are now applying the best-performing trypsin in their workflows.
