Automated Process of Q-PCR/Gene Expression

摘要

PCR-based fluorescent detection assays for the relative and quantitative measurement of gene expression, such as Taq Man™, LUX™, and SYBR Green™, are currently in wide spread use due to their general applicability, low cost, reproducibility, accuracy, and ease of use. One current limitation of quantitative PCR (Q-PCR) is the lack of a fully integrated and high-throughput method for general genomic and diagnostic applications. Here we report a reliable and high-throughput system for the automated extraction of RNA, first-strand cDNA synthesis, quality control measures, consecutive real-time PCR amplification, and primary data analysis. As described, this procedure utilizes commonly available reagents and pre-packaged “kits” for RNA extraction, first strand cDNA synthesis, Q-PCR, liquid handling, and capillary electrophoresis that are generally applicable to a wide variety of robotic platforms.
