The ABI QuantStudio™ 7 Flex real-time fluorescence quantitative PCR system achieves various applications of real-time fluorescence quantitative PCR through its multi-channel function and interchangeable module form. Mainly used for gene expression (mRNA) analysis, microRNA (miRNA) analysis, genetic variation analysis (such as SNP genotyping, drug metabolizing enzyme (DME) and copy number variation (CNV) analysis), protein expression analysis, mutation detection (such as cancer somatic mutation analysis), FTR gene mutation analysis, biomarker analysis.
