In this podcast Barry Jones (Director, LC–MS Biologics and Biomarkers at Q² Solutions) and Adriane Spytko (Manager, LC–MS Biologics at Q² Solutions; both NY, USA) discuss hybrid assays using both LBA and LC−MS techniques. They share their thoughts on bottom-up LC−MS methods and the concern about detecting analyte that is not intact as well as future projects that bridge LC−MS and LBA.
