The majority of workhorse mass spectrometric instrumentation currently claim an average limit of detection (LOD) of approximately 10 amol or 6 million 50-kDa protein molecules, which is orders of magnitude higher than where the field was just a decade ago, but still correlates with challenges associated with analyzing very low level biological materials. Biotechnol. However, this does mean that it is standard to only identify less than half of the spectra in a typical bottom up workflow. While this complicates target deconvolution, it can allow on the other hand the observation of broader aspects of the compound MoA and effects on downstream processes. Chem. Nat. While these resources have proven invaluable to early target identification, as targets get closer to clinical trials protein expression must be validated to limit potential toxic effects of therapeutic intervention. Lemmon, M. A., Schlessinger, J. Mathieson, T. et al. Dalton, S. E. et al. This is supported by the fact that the authors found 240 HLA-I associated peptides from these distinct ORFs.
