Nature Biotechnology Publishes First Paper Describing NanoString's Technology

(Nanowerk News) NanoString Technologies today announced the first peer-reviewed publication describing NanoString’s technology will be published in the Nature Biotechnology March 7th issue and is available in the Advanced Online Publication section today ("Direct multiplexed measurement of gene expression with color-coded probe pairs").
The paper entitled Direct Multiplexed Measurement of Gene Expression with Color-Coded Probe Pairs describes the performance of the nCounter Analysis System, which captures and counts individual mRNA transcripts by a novel molecular bar-coding technology. The new platform was compared to microarrays, TaqMan® PCR, and SYBR®Green real-time PCR and results demonstrated that the nCounter system is more sensitive than microarrays and is similar in sensitivity to real-time PCR. The paper describes experiments using nCounter CodeSets to profile the expression of 509 human genes in a single multiplexed assay, analysis of a gene set that overlaps with the MAQC gene expression study and quantitation of transcript levels for 21 sea urchin genes across 7 embryo samples. Results demonstrated a remarkable correlation in the pattern of gene expression between NanoString technology and real-time PCR at all transcript levels. The paper was a result of a collaboration between scientists at NanoString Technologies, Dr. Roger Bumgarner at the University of Washington, Dr. Eric Davidson at the California Institute of Technology, and Dr. Leroy Hood at the Institute of Systems Biology.
The nCounter Analysis System uses a novel digital technology that enables direct multiplexed measurement of gene expression and offers high levels of sensitivity and precision, including detection of fractional fold change differences, a feature unique to this platform. The technology uses molecular barcodes and single molecule imaging to detect and count hundreds of unique transcripts in a single reaction. The system is comprised of a fully automated sample prep station, a digital analyzer, the CodeSet (molecular barcodes) and all other reagents needed to perform the analysis and is ideally suited for researchers seeking to validate gene expression signatures, working with small amounts of starting material or studying defined gene sets.
“The nCounter technology is a unique and direct way to measure gene expression. In this paper we show that the technology analyzes hundreds of genes in a single reaction, produces measurements that are comparable to, or better than, microarrays and are comparable to qPCR,” said Dr. Roger Bumgarner, Associate Professor and Director, Center for Array Technologies at the University of Washington. “However, the key aspect of this technology is that the method is scalable to large numbers of samples at relatively modest cost. As such, it has the potential to revolutionize the application of gene expression measurements to patient diagnoses.”
Dr. Leroy Hood, President of the Institute for Systems Biology explained, “The digital analysis of RNA will become one of the most important techniques in modern biology. The NanoString approach represents one of the first digital RNA counting technologies—and it opens up the possibility of transforming how we think about transcriptomes—especially for transcripts expressed at low levels.”
“We are looking forward to the increase in efficiency and accuracy that results from the use of the NanoString technology for system level analysis of gene expression in our research into gene regulatory networks,” added Dr. Eric Davidson, Professor of Cell Biology at California Institute of Technology.
The nCounter Analysis System is now available commercially. For more information please visit NanoString Technologies at
