This disclosure provides an integrated and automated sample-to-answer system that, starting from a sample comprising biological material, generates a genetic profile in less than two hours. In certain embodiments, the biological material is DNA and the genetic profile involves determining alleles at one or a plurality of loci (e.g., genetic loci) of a subject, for example, an STR (short tandem repeat) profile, for example as used in the CODIS system. The system can perform several operations, including (a) extraction and isolation of nucleic acid; (b) amplification of nucleotide sequences at selected loci (e.g., genetic loci); and (c) detection and analysis of amplification product. These operations can be carried out in a system that comprises several integrated modules, including an analyte preparation module; a detection and analysis module and a control module.
本公开提供了一种集成的自动采样-应答系统,该系统可从包含
生物材料的样本开始,在两小时内生成
基因图谱。在某些实施方案中,
生物材料是 DNA,
基因图谱涉及确定受试者一个或多个位点(如
基因位点)上的等位
基因,例如,STR(短串联重复)图谱,例如 CODIS 系统中使用的图谱。该系统可执行多项操作,包括:(a) 提取和分离核酸;(b) 扩增选定位点(如
基因位点)的核苷酸序列;(c) 检测和分析扩增产物。这些操作可在一个由多个集成模块组成的系统中进行,包括分析物制备模块、检测和分析模块以及控制模块。
