Project Abstract In this Administrative Supplement grant application, we request funds to purchase a new cell sorter (S3e™ Cell Sorter, Bio-Rad). This state of art cell sorter will enable us to evaluate large size gene knock-in events, including both on-target knock-in, on-target insertion/deletion (indel) rates as well as potential off-target knock-in and indel events, at the single cell resolution. In Aim 1, we plan to use this cell sorter to evaluate mi-spCas9-v2. In Aim 2, we will use this cell sorter to evalute mi-saCas9. In Aim 3, we will use this cell sorter to evaluate the efficacy and safety profiles of miCas9 in clinically relevant applications. As a results, this new cell sorter, once equipped, will generate more convincing data to demonstrate the advantages of the proposed miCas9 gene editing nucleases.

项目摘要 在此行政补充申请中，我们要求资金购买新单元 分散者（S3E™细胞分散者，生物拉德）。这种最先进的细胞分辨率将使我们能够评估大量 尺寸的基因敲入事件，包括靶向敲门，目标插入/删除（Indel） 在单细胞分辨率下，速率以及潜在的脱靶敲入和indel事件。目标 1，我们计划使用此细胞分辨率来评估MI-SPCAS9-V2。在AIM 2中，我们将使用此细胞分辨率 评估MI-SACAS9。在AIM 3中，我们将使用此细胞分选项来评估效率和安全性 MICAS9在临床相关应用中的轮廓。结果，这个新的细胞分系程序一次 装备有，将产生更具说服力的数据来证明所提出的优势 云母基因编辑核。
