Measuring protein ligand binding with an endogenous HiBiT CETSA test system
21 Feb 2024In this application note, BMG LABTECH introduces the HiBiT CETSA, a method for measuring protein-ligand binding in a tracer-free manner. This approach can improve the screening for new ligands by allowing the measurement of endogenous full-length proteins. The HiBiT CETSA detects interactions between proteins and potential ligands by determining the protein's melting point along a heat gradient. The assay allows plotting the temperature against the detected luminescence, and subsequently, the melting curves are analyzed to identify compound-induced thermal shifts.

Combinatorial ChemistryCombinatorial chemistry, also known as combichem, is a technique used in drug discovery to create libraries of structurally related compounds. A library is generated by synthesis with a chemical reactor system or by computer-based modeling of compound combinations. When undertaking combinatorial chemistry consider reagents, buffers, resins and standards.MicroplatesMicroplates are multi-well plates used to increase the throughput of biological investigations. The number of wells microplates contain can range from 6 to 3243 wells, with the 96-well format being the most commonly used. Microplates can come tailored for a range of applications including cell culture, PCR, filtration, storage, non-binding surface, protein crystallization, as well as pre-coated, deep well and normal Standard microplates. Additionally, options for microplate colors include clear , black, white or black with clear bottom and white with clear bottom for absorbance microplate reader applications.

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.Microplate Readers / DetectorsMicroplate readers are used to automate the detection and analysis of labeled or label-free components in microplates during assays or live-cell monitoring. Microplate readers are generally distinguished by their mode of detection. Types include absorbance, luminescence, fluorescence intensity, fluorescence polarization, TRF / FRET and multimode microplate readers. Microplate readers deliver a high throughput of samples by reading multiple wells simultaneously, with the 96-well format the most commonly used. As a result, microplate readers are often used in the drug discovery, bioassays, research and pharmaceutical industries for screening applications. Microplate loading can also be automated, with robotic microplate stackers to increase throughput.

Drug delivery is often approached via the biopharmaceutical or small molecule drug's formulation, but it may also involve medical devices or drug-device combination products. Considerations include instrumentation, software and services. Protein QuantificationThe detection and quantification of proteins in a sample is vital across life sciences, pharmaceutical research and clinical diagnostics, and a variety of equipment is available to scientists to simplify the workflow. 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.
