  • Publication number: 20230212559
    Abstract: The present disclosure provides chimeric primers suitable for use in the amplification of a nucleic acid sequence. In some aspects, these chimeric primers reduce the formation of primer dimers and/or off-target amplification products, compared to amplification reactions carried out using unmodified primers.

  • Patent number: 11578357
    Abstract: The invention relates to reagents and methods for improving the efficiency of multiplex nucleic acid amplification, in particular where overlapping amplicons are to be generated. The invention also relates to reagents and methods for improving the efficiency of multistep nucleic acid amplification, in particular the performance of two separate amplification reactions designed to occur in sequence in the same reaction mixture or vessel. The invention further relates to reagents and methods for improving multistep nucleic acid amplification reactions by controlling the output of the first amplification reaction. In particular, primers are provided that minimise the formation of aberrant amplification products. Such primers are particularly useful where first and second amplification reactions take place in a single reaction mixture or vessel.

  • Publication number: 20200318174
    Abstract: In alternative embodiments, provided are methods comprising use of FISH, IHC or equivalent gene fusion detection protocols, and gene sequencing, wherein optionally the gene sequencing is high throughput or next generation gene sequencing, for the identification and characterization of gene abnormalities such as gene breakages; optionally gene breakages comprise gene translocation, gene rearrangements and/or gene inversions. In alternative embodiments, genes or transcripts are analyzed from individuals suspected of having cancer, and the analysis is carried out on biological samples taken from these individuals. This identification and characterization of gene abnormalities can be used in the diagnosis and treatment of a cancer.

  • Patent number: 10767228
    Abstract: The invention relates to prenatal detection methods using non-invasive techniques. In particular, it relates to prenatal diagnosis of a fetal chromosomal aneuploidy by detecting fetal and maternal nucleic acids in a maternal biological sample. More particularly, the invention applies multiplex PCR to amplify selected fractions of the respective chromosomes of maternal and fetal chromosomes. Respective amounts of suspected aneuploid chromosomal regions and reference chromosomes are determined from massive sequencing analysis followed by a statistical analysis to detect a particular aneuploidy.
