Transcript

Drug screening techniques include high-throughput screening, which uses automation for drug discovery, structure-based designs, and find receptor binding molecules based on the structure, and a fragment-based design, which uses nuclear magnetic resonance and mass spectrometry to optimize molecular fragments and identify the compounds. The DAM system measures fly sleep by detecting infrared beam bricks. However, this method can overestimate sleep if the flies remain static at one end of the tube, or if the fly is not highly mobile.

Furthermore, the order of any tested drug may impact the fly fruit intake, potentially skewing experimental results. Therefore, our experiment will incorporate various stretches to mitigate these factors and enhance accuracy. Compared with video analysis based methods, our method offers high-throughput capabilities, reduce the cost, and simplify operation.

So process of experimental data is also relatively straightforward, where the resulting graph visually represents the drug's effects.

Summary

Presented is a protocol for high-throughput drug screening to improve sleep by monitoring the sleep behavior of fruit flies in an elderly Drosophila model.
