This work focused on scaling-down a monoclonal antibody SEC method, starting with a typical analytical-size SEC column (YMC-Pack Diol 5um, 300Å, 300x8.0mm) and ending with a small particle, shorter length, narrower-bore column (YMC-pack Diol 2um, 300Å, 150x4.6mm). The purpose of this experiment was to detail the differing performance characteristics exhibited by each column as physical properties were altered, one variable at a time.
Nano-liquid chromatography-high-resolution tandem mass spectrometry (nano-LC-HRMS/MS) reveals saliva protein shifts before and after multiple sclerosis therapy.
Max Besenhard explains how hybrid mechanistic and machine learning models can make HPLC method development quicker, more robust and ready for autonomous digital twins.
