Measuring protein thermal stability and phosphorylation changes to capture early cellular responses to small molecule drugs

14 Nov 2023

In this scientific poster, Pelago Bioscience presents the measurement of protein thermal stability and phosphorylation changes as a strategy to capture early cellular responses to small molecule drugs. Both target engagement (CETSA®) and cellular signaling (phosphoproteomics) methods are employed to capture these responses. Changes in binding specificity result in downstream phosphorylation events and underscores the value of parallel CETSA and phosphoproteomics analysis for obtaining comprehensive data on the specificity and mechanism of action of kinase inhibitors.

ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

Proteins of interest can be easily labeled and detected on light-based detection instruments. Immunoassay kits allow you to identify a specific protein of interest and protein detection beads or antibody microarrays allow you to identify multiple specific proteins at once. Protein interactions and enzyme activity can also be monitored with protein-protein interaction assays. Additionally, the biophysical characterization of proteins is made easy with biokinetic analyzers.

Produce recombinant proteins with expression vectors in combination with a host cell suitable for high-level protein expression. For production of toxic proteins, consider cell-free expression vectors. Create and monitor post-translational modifications with protein modification kits.
