Solution
- The high-throughput research on RNA at the transcriptional level provides an important research method for people to deeply understand the transcriptional regulation, signal transduction mechanism, and molecular pathological typing of diseases in biological processes.Commonly used high-throughput research methods such as gene chips and RNA sequencing can generate a large amount of information. However, these technologies require high sample quality and are expensive and the experimental results often need to be verified by qPCR. However, when conducting quantitative research on multiple genes, the traditional qPCR method cannot meet the needs of quantitative detection of multiple genes due to many and complicated experimental steps and obviously insufficient throughput. In addition, clinical samples are usually FFPE samples, which will cause a large amount of RNA degradation and fragmentation during preparation and storage. Therefore, both qPCR and RNA-seq are difficult to perform accurate quantitative analysis on such samples.For the above problems, NanoString gives a perfect solution.The NanoString digital gene analysis system based on the principle of hybridization directly detects individual mRNA transcripts marked by barcode probes, and quantifies them by digital counting. This process does not require enzymatic and amplification processes, and only 100 ng of RNA can accurately quantify more than 800 specific mRNA transcripts. The sensitivity and accuracy of its detection are comparable to real-time quantitative PCR (RT-PCR) technology.
- Nanostring technology can directly quantify RNA in FFPE samples, cell lysates and even whole blood without RNA extraction. This could further reduce the potential biases that may be caused by the extraction process.In recent years, NanoString technology has been widely applied to the frontier fields of biopharmaceutical, including the validation of high-throughput gene expression results, gene expression profiling studies, gene regulatory network research, and clinical disease molecular classification, diagnosis and prognosis.
