Welcome to the new era of quantitative targeted gene and microRNA expression profiling using eBiosciences’ QuantiGene Plex assays. The QuantiGene system efficiently measures up to 80 RNA targets per sample directly from a variety of sample types, effectively bypassing RNA isolation, with no cross-reactivity. By utilizing branched DNA (bDNA) signal amplification technology on Luminex xMAP beads, these assays can distinguish percentage differences in RNA copy number with a low coefficient of variation, less than 15% for the entire process. Click here for more information on the Luminex xMAP technology.

The QuantiGene workflow has also removed the reverse transcription and PCR amplification steps which eliminates any associated artifacts and enables reduced sample consumption. These assays can also directly quantify ncRNA, fusion transcripts, and DNA copy number variations. QuantiGene assays are utilized to advance research in numerous disease areas, including multiple focus areas in oncology; gastrointestinal stromal tumors, lung, pancreatic, breast, colorectal, and prostrate cancers1-8.

ORB provides cost-effective customizable QuantiGene assays to rapidly characterize mRNA and microRNA targets as standalone projects or confirmation studies following broader interrogation strategies such as RNA sequencing and gene expression and microRNA microarray. To support biomarker discovery projects, ORB’s predictive modeling analyses can be used to select the best performing targets for validation using QuantiGene assays.  Follow the links below to learn more about related applications.
