CRISPR-Cas系统和抗CRISPR蛋白被整合到 酿酒酵母的布尔门方案中。新的小逻辑电路表现出良好的性能,加深了对基于dCas9/dCas12a的转录因子和抗CRISPR蛋白性质的理解。

我们的协议解释了如何设计、构建和分析利用二型和五型CRISPR dCas系统以及相应的抗CRISPR蛋白的酵母基因数字电路。它是组装停留,因为它收集了零标准程序来组装和测试服务中的合成转录网络。首先,制备含有20至40纳克DNA模板,1微升正向引物,1微升反向引物,5微升DNTP混合物,0.5微升DNA聚合酶,10微升5x DNA聚合酶反应缓冲液和双蒸水的反应混合物,总体积为50微升。

如手稿中所述,在热循环仪上使用触地PCR程序扩增DNA序列。通过凝胶电泳分离PCR产物,并通过DNA凝胶提取试剂盒稀释琼脂糖凝胶中的DNA序列。使用Gibson组装方法,将纯化的PCR产物插入切开式穿梭载体中,方法是让等摩尔DNA混合物在50摄氏度下进入一小时。
