  • Publication number: 20140221217
    Abstract: The invention relates to a method for the detection of a target nucleotide sequence in a sample based on an oligonucleotide ligation assay wherein probes are used that contain (a combination of) sequence-based identifiers that can identify the sample and the target sequence (i.e. locus and/or allele combination) wherein after the ligation step, the ligated probes, or after amplification, the amplified ligated probes, are restricted using restriction enzymes to cut of part of the probes and continue with those parts (identifiers and target sequence) that contain the relevant information in the sequencing step.

  • Publication number: 20140206551
    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.
