16 Nanostring Molecular Barcodes The technology uses molecular "barcodes" and single molecule imaging to detect and count hundreds of unique transcripts in a single reaction. Each color-coded barcode is attached to a single target-specific probe corresponding to a gene of interest. Mixed together with controls, they form a multiplexed CodeSet. The Reporter Probe carries the signal; the Capture Probe allows the complex to be immobilized for data collection. Gene Expression CodeSets for the nCounter Analysis System offer a cost-effective way to analyze the expression levels of up to 800 genes simultaneously with sensitivity comparable to qPCR. +miRNA + CNV
17 Applied BioCode: digital arrays Applied BioCode, Inc. (ABC) has combined photolithographic digital barcodes with immuno- and molecular chemistry to create a new, patented Barcoded Magnetic Bead (BMB) technology. Barcoded Magnetic Bead has one of the highest multiplex capacities available (up to 1,024 targets/ assay). Optically bar-coded beads are mass produced at low cost by well established semiconductor processes. These beads are functionalized with nucleic acids, proteins or other probe molecules, allowing highly multiplexed assays to be carried out in homogeneous or heterogeneous media. The BMBs barcode patterns give a high-contrast transmitted signal and no fluorescence background, allowing the barcode to be identified easily and accurately, with near 100% decoding accuracy.

Multi-Processing of individual arrays: Osmetech Osmetech eSensor (previously CMS division from Motorola) At the core of the eSensor detection technology are DNA fragments attached to electrodes on the surface of a small circuit board. This DNA microarray is the basis of detection by the eSensor System for any DNA sequence. Each electrode is electronically active and detects a different DNA sequence. Finding the complimentary sequence in the target DNA generates a characteristic electrical signal. Each eSensor DNA Detection System cartridge can detect several different DNA targets at once, providing a cost-effective platform for complex analysis. 24 eSensor CF test: 23 mutations tested for in the ACOG/ACMG-recommended cystic fibrosis carrier screening panel.

High Throughput SNP detection:104 portable to routine MDx? Screening for a large set of SNP is still high end and technical demanding Large set of SNP studies more related to research and clinical studies rather than routine MDx However, more and more SNP are related with disease-associations. So still a high potential for MDx developments. How these technologies will face the $100 full genome sequencing era? Technologies for 1m SNPs vs Full genome sequence with >5m SNPs?

Illumina-Solexa Technology 116The approach relies on attachment of randomly fragmented genomic DNA to a planar, optically transparent surfaceand solid phase amplification to create an ultra-high density sequencing flow cell with >10 million clusters, eachcontaining ~1,000 copies of template per sq. cm. These templates are sequenced using a very robust four-colorDNA sequencing-by-synthesis technology that employs reversible terminators with removable fluorescence.

AB SOLID high throughput 121 How it Works Start with a fragment or mate-paired library depending on the application and information you need. Prepare clonal bead populations in microreactors containing template, PCR reaction components, beads and primers. After PCR, you denature the templates and perform a bead enrichment step to separate beads with extended templates from undesired beads.
