The proteome integral solubility alteration (PISA) assay is widely used for identifying drug targets, but it labor-intensive and time-consuming requires a substantial amount of biological sample. Aiming at enabling automation greatly reducing the sample amount, we developed one-pot time-induced (OPTI)-PISA. Here, demonstrate OPTI-PISA performance on targets multiple drugs in cell lysate scaling down to sub-microgram levels, making PISA method suitable NanoProteomics. can be implemented using only standard equipment proteomics lab.

Drug development is plagued by inefficiency and high costs due to issues such as inadequate drug efficacy unexpected toxicity. Mass spectrometry (MS)-based proteomics, particularly isobaric quantitative offers a solution unveil resistance mechanisms unforeseen side effects related off-targeting pathways. Thermal proteome profiling (TPP) has gained popularity for target identification at the scale. However, it involves experiments with multiple temperature points, resulting in numerous samples considerable variability large-scale TPP analysis. We propose high-throughput discovery workflow that integrates single-temperature TPP, fully automated proteomics sample preparation platform (autoSISPROT), data independent acquisition (DIA) quantification. The autoSISPROT enables simultaneous processing of 96 less than 2.5 hours, achieving protein digestion, desalting, optional TMT labeling (requires an additional 1 hour) 96-channel all-in-tip operations. results demonstrated excellent performance >94% digestion efficiency, >98% >0.9 intra- inter-batch Pearson correlation coefficients. By automatically 87 samples, we identified both known targets potential off-targets 20 kinase inhibitors, affording over 10-fold improvement throughput compared classical TPP.

Limited proteolysis coupled with mass spectrometry (LiP-MS) has emerged as a powerful technique for detecting protein structural changes and drug-protein interactions on proteome-wide scale. However, there is no consensus the best quantitative proteomics workflow analyzing LiP-MS data. In this study, we comprehensively benchmarked two major quantification approaches-data-independent acquisition (DIA) tandem tag (TMT) isobaric labeling-in combination LiP-MS, using drug-target deconvolution assay model system. Our results show that while TMT labeling enabled of more peptides proteins lower coefficients variation (CVs), DIA-MS exhibited greater accuracy in identifying true drug targets stronger dose-response correlation peptides. Additionally, evaluated performance freely available (FragPipe) versus commercial (Spectronaut) software tools analysis, revealing choice between precision sensitivity largely depends specific experimental context. findings underscore importance selecting appropriate strategy based study objectives. This work provides valuable guidelines researchers discovery, highlights how advancements instrumentation, such Astral spectrometer, may further improve sequence coverage, potentially reducing need labeling.
