In this webinar, Dr. Cooper will discuss a novel workflow for spatial profiling of intact proteins on tissue slices utilizing native LESA MS to identify larger proteins (>47 kDa) than previous research, as well detecting and characterizing protein complexes with molecular weights ca. 103 kDa, demonstrating the softness of the ionization and transmission of protein complexes through FAIMS. Higher order MSn is performed to dissociate the complexes into subgroups, and sequence subgroups using multiple dissociation techniques. Combining FAIMS with LESA MS has enabled detection of hundreds of proteins in human liver sections.
