We have developed a procedure for massively parallel resequencing of multiple human genes by combining a highly multiplexed and target-specific amplification process with a high-throughput parallel sequencing technology. The amplification process is based on oligonucleotide constructs, called selectors, that guide the circularization of specific DNA target(More)
Detection and identification of pathogens in environmental samples for biosecurity applications are challenging due to the strict requirements on specificity, sensitivity and time. We have developed a concept for quick, specific and sensitive pathogen identification in environmental samples. Target identification is realized by padlock- and proximity(More)
We describe a scheme for biomolecule enumeration by converting nanometer-scale specific molecular recognition events mediated by rolling-circle amplification to fluorescent micrometer-sized DNA molecules amenable to discrete optical detection. Our amplified single-molecule detection (SMD) approach preserves the discrete nature of the molecular population,(More)
During the past two years, significant breakthroughs have been achieved in genetic analyses through the application of technologies based on analytical DNA-circularization reactions. Padlock probes and molecular inversion probes have enabled parallel, high-throughput single nucleotide polymorphism (SNP) genotyping at increased scales, whereas, at the other(More)
We present a method to specifically select large sets of DNA sequences for parallel amplification by PCR using target-specific oligonucleotide constructs, so-called selectors. The selectors are oligonucleotide duplexes with single-stranded target-complementary end-sequences that are linked by a general sequence motif. In the selection process, a pool of(More)
The World Organization for Animal Health (Office International des Epizooties, OIE) includes the diseases caused by foot-and-mouth disease virus (FMDV), swine vesicular disease virus (SVDV), and vesicular stomatitis virus (VSV), as "Diseases Notifiable to the OIE". Foot-and-mouth disease (FMD) outbreaks have severe economical as well as social effects and(More)
DNA microarrays serve to monitor a wide range of molecular events, but emerging applications like measurements of weakly expressed genes or of proteins and their interaction patterns will require enhanced performance to improve specificity of detection and dynamic range. To further extend the utility of DNA microarray-based approaches we present a(More)
Targeted genome enrichment is a powerful tool for making use of the massive throughput of novel DNA-sequencing instruments. We herein present a simple and scalable protocol for multiplex amplification of target regions based on the Selector technique. The updated version exhibits improved coverage and compatibility with next-generation-sequencing (NGS)(More)
We describe PieceMaker, a software tool for the design of applications of selector probes-oligonucleotide probes that direct circularization of target nucleic acid molecules. Such probes can be combined in parallel to circularize a selection of fragments from restriction digested total genomic DNA. These fragments can then be amplified in a single PCR using(More)
Highly specific high-throughput assays will be required to take full advantage of the accumulating information about the macromolecular composition of cells and tissues, in order to characterize biological systems in health and disease. We discuss the general problem of detection specificity and present the approach our group has taken, involving the(More)
