Transcript
这是第一篇解决从细胞外囊泡中产生的小RNA测序技术问题的论文。NGS 样品需要严格的制备和质量控制。由于EV的性质,EV样品的QC过程偏离了标准。
该协议的优点是其中为首次使用的用户执行的 QC 步骤。演示程序将是苏俊义,一个研究助理,从我的实验室。首先,在5个T175烧瓶中,以每平方厘米2000个细胞的填充人类中质干细胞。
然后在5%的二氧化碳环境中在37摄氏度下生长细胞,每两到三天更换一次介质,直到获得5个90%汇合细胞的烧瓶。接下来,用每瓶20毫升PBS清洗细

Summary
该协议演示了如何从细胞培养培养基中纯化细胞外微 rna, 用于小型 rna 文库构建和下一代测序。描述了各种质量控制检查点, 以使读者了解在处理低输入样本 (如 exrna) 时的预期结果。
