-
摘要: 目的研究适合基层法医DNA实验室建立DNA数据库的新产品和方法.方法采用国产Goldeneye 20A-M免提取试剂盒对3 977份多种建库人体生物检材进行检测,并对多种人体生物检材的结果进行比较.同时探索Whatman FTA卡的洗脱方法.结果直接用免提取试剂盒进行实验研究,检出率为99.4%,对保存了1 a的普通血滤纸、棉签血痕、纱布血痕、AuSBio卡、公安部物证鉴定中心监制的采血卡检出成功率高达100%,口腔拭子和FTA分别为97.1%和98.5%.Whatman FTA卡经过1%的Triton X-100洗脱1次,检出成功率可以达到100%.结论 Goldeneye 20A-M免提取试剂盒可以用多种载体人体生物检材做为直扩样本进行DNA建库,是一种简单、快捷的DNA建库方法.
