中文摘要
在此期间,项目团队完成了高通量筛选平台的实验条件优化,该平台能够使用基于酶的方法测量细胞中染色质可及性的动态状态(Assay for Transpose-Accessible chromatin, ATAC)。该小组已经验证了一种ATAC DNA的粗制方法,该方法节省了大量成本并提高了产量。利用优化后的检测方法,利用以表观遗传学为重点的小分子文库进行了中试筛选,活性化合物正在进行进一步的表征。
英文摘要
During this period, the project team has completed optimization of experimental conditions of a high-throughput screening platform capable of measuring dynamic states of chromatin accessibility in cells using an enzyme-based approach (Assay for Transpose-Accessible Chromatin (ATAC)). The group has validated a crude preparation approach for the ATAC DNA that saves significant cost and increases throughput. Using the optimized assay, a pilot screen was performed using an epigenetic-focused small molecule library, and active compounds are undergoing further characterization.
