ProteomicsOne-Pot Time-Induced Proteome Integral Solubility Alteration (OPTI-PISA) assay for automated and sensitive drug target identification
Proteome Integral Solubility Alteration (PISA) assay is widely used for identifying drug targets, but it is labour-, sample and time-consuming. Aiming at enabling automation and greatly reducing the sample amount, we developed One-Pot Time-Induced (OPTI)-PISA. Here we demonstrate OPTI-PISA performan...

ProteomicsSelection of Heating Temperatures Improves the Sensitivity of Proteome Integral Solubility Alteration (PISA) Assay
The thermal shift assay is a robust method of discovering protein-ligand interactions by measuring the alterations in protein thermal stability under various conditions. Several thermal shift assays have been developed and their throughput has been advanced greatly by the rapid progress in tandem ma...

ProteomicsProteome integral solubility alteration assay for monitoring antibody-antigen interactions in cells
Proteome Integral Solubility Alteration (PISA) assay is normally used for characterization of the interactions between a small molecule and the cellular proteome. Here we modified PISA uniquely to identify the antigen (tumor necrosis factor alpha) in activated monocytes using the monoclonal antibody...

ProteomicsImproved drug-target deconvolution with PISA-DIA using an extended, overlapping temperature gradient
For target-engagement applications, a comparative analysis was performed to assess the suitability, ease of implementation and cost-effectiveness between Cellular Thermal Shift Assay (CETSA) and Proteome Integral Solubility Alteration (PISA). Human multiple myeloma cells U266B1 cell lysate was treat...

ProteomicsProteome Integral Solubility Alteration (PISA): a high-throughput proteomics assay for target deconvolution
Various agents, including drugs as well as non-molecular influences, induce alterations in the physic-chemical properties of proteins in cell lysates, living cells and organisms. These alterations can be probed by applying a stability-modifying factor, such as elevated temperature, to a varying degr...

ProteomicsMultifaceted proteome analysis at solubility, redox, and expression dimensions for target identification
Multifaceted interrogation of the proteome deepens the system-wide understanding of biological systems; however, mapping the redox changes in the proteome has so far been significantly less informative than expression and solubility/stability analyses. Here, we devise the first high-throughput redox...

ProteomicsSystem-wide profiling of drug residence time by proteome integral solubility alteration assay
Most drugs used in the clinic and drug candidates target multiple proteins, and thus detailed characterization of their efficacy targets is required. While current methods rely on quantitative measurements at thermodynamic equilibrium, kinetic parameters such as the residence time of a drug on its t...

ProteomicsProteome integral solubility alteration high-throughput proteomics assay identifies Collectin-12 as a non-apoptotic microglial caspase-3 substrate.
Caspases are a family of proteins mostly known for their role in the activation of the apoptotic pathway leading to cell death. In the last decade, caspases have been found to fulfil other tasks regulating the cell phenotype independently to cell death. Microglia are the immune cells of the brain re...
