Abstract

We developed a simple 3D printed cartridge for mass spectrometry (MS) targeted detection of plasma proteins, including post-translational modifications (PTMs). The cartridge uses an integrated antibody enrichment column to preconcentrate the protein target as well as a novel built-in substrate to ionize the protein targets for MS detection. We show several examples of using this cartridge to perform rapid detection of clinically significant proteoforms from plasma samples.
