NEXTflex 18S ITS Amplicon-Seq Kit和NGS一起可以方便高效的检测真核群落的组成。
快速的18S分析
18S ITS 建库实验流程中涉及到2步扩增过程:利用定制的PCR引物,对目标ITS 区域进行初始PCR扩增;随后,连接测序barcodes后的第二次扩增。限定的磁珠纯化次数确保下游扩增子的回收率。
低PCR偏差,高目标序列读取率实验流程
NEXTflex 18S ITS Amplicon-Seq Kit 所得测序结果比传统18S 测序建库试剂盒要好,流程中采用2步PCR,以增加样本特异性index,减少扩增子测序中的目标序列脱靶率。
产品特点:
低PCR偏差和高目标序列读取率
快速18SITS1和ITS2文库制备的方案
低样品量-低至1ng的基因组DNA
灵活的barcode选择-多达384的独特barcodes可运用
测序引物都包含在此试剂盒中
匹配PE的Sciclone NGS和NGSx自动工作站
经IlluminaMiSeq测序平台验证
