Q. 如何理解寻因生物的SeekOne® DD 单细胞 DNA甲基化+RNA 双组学技术
SeekOne® DD 单细胞 DNA甲基化+RNA 双组学技术,支持一次实验灵活捕获500-1200细胞,可在同一细胞中实现单细胞5’转录组与DNA甲基化信息的并行捕获。该试剂盒基于微流控芯片技术,整合了带有细胞条形码的凝胶微珠(Barcoded Beads)与油包水液滴(Water-in-Oil)系统,仅需一个细胞标签即可同步构建5’转录组与DNA甲基化两大核心文库。其中,转录组 cDNA 产物可直接用于免疫组库文库构建,匹配免疫相关研究需求;同时,DNA 甲基化数据可额外挖掘拷贝数变异(CNV)信息,进一步拓展基因组层面的研究维度。在单细胞精度下,研究者得以同时分析基因表达(转录组)、表观遗传修饰(DNA 甲基化)、基因组变异(CNV)、免疫功能(免疫组库)多维度信息,以揭示细胞异质性、追踪调控网络、解析表观遗传信息。
