In the realm of screening technologies, one of the original research pieces introduces a novel application of the enzyme-linked immunosorbent assay (ELISA) adapted for discovering protein-protein interaction inhibitors. Utilizing the spirochete flagellar hook as a test case, the research demonstrates how this assay effectively identifies compounds that disrupt lysinoalanine crosslinking between protein subunits. Screening a substantial chemical library of approximately 700 molecules, the study not only reaffirms the inhibitory effects of known compounds but also uncovers promising new candidates, including honokiol and zafirlukast. This innovative assay platform promises to accelerate the identification of small molecules capable of targeting intricate protein interfaces, which have historically been challenging to drug.

Another pioneering work addresses throughput bottlenecks in cellular thermal shift assays (CETSA), a technique used to confirm drug-target engagement in biological contexts. Two remarkable technological advancements are presented: an isothermal 1536-well ultra-high throughput screening (uHTS) platform featuring controlled thermal ramp-up combined with luminescence detection, and a Gradient Peltier Device that facilitates comprehensive melt curve analysis in a single assay plate. These technological strides overcome longstanding limitations of scale and resolution in thermal shift assays. Validation against fluorescence polarization data using the androgen receptor as a benchmark affirms the robustness and sensitivity of these improvements, underscoring their suitability for large-scale screening campaigns.

Further advancing drug-target engagement quantification, the MICRO-TAG method emerges as a novel fluorescence-based split-RNase S complementation assay. Unlike traditional thermal shift methods that rely on a single melting temperature, MICRO-TAG quantifies binding across programmable temperature series within living cells. Tested on key oncogenic and cellular proteins including MAPK1, KRAS, and UBE2N, this approach offers a sensitive, scalable, and physiologically relevant alternative to in vitro biophysical assays. Such advances could substantially improve early-stage drug discovery by providing accurate engagement data directly in cell-based contexts.
