  • Patent number: 8178300
    Abstract: The present invention relates to a high throughput method for the identification and detection of molecular markers wherein restriction fragments are generated and suitable adaptors comprising (sample-specific) identifiers are ligated. The adapter-ligated restriction fragments may be selectively amplified with adaptor compatible primers carrying selective nucleotides at their 3? end. The amplified adapter-ligated restriction fragments are, at least partly, sequenced using high throughput sequencing methods and the sequence parts of the restriction fragments together with the sample-specific identifiers serve as molecular markers.

  • Patent number: 7217516
    Abstract: The present invention discloses methods for identifying and analysing microsatellite-associated polymorphisms between different DNA samples. Different DNA samples, e.g. from different individuals, are analysed using a PCR based on the combination of a RAMP-primer and an AFLP-primer and polymorphisms between the different DNA samples are identified. The polymorphisms thus identified may be isolated and further analysed by e.g. DNA sequence analysis both upstream and downstream from the microsatellite-associated polymorphism. These sequences may subsequently be used to devise and synthesise new means for analysis of the polymorphic locus, such as e.g. PCR-primer pairs or oligonucleotide probes.
