  • Patent number: 12215314
    Abstract: The invention relates to integrated DNA and RNA library preparations and methods of making and uses thereof, wherein the DNA molecules are labelled with a tag identifying the molecule as being a DNA molecule and the RNA molecules are labelled with a tag identifying the molecule as being a RNA molecule. The methods do not require physical separation of DNA and RNA.

  • Publication number: 20200354773
    Abstract: The present disclosure provides methods and kits for performing high multiplex PCR using molecular barcodes. The methods disclosed herein separately extend a set of primers (BC primers) that each comprise a molecular barcode and a target-specific sequence, and amplify the resulting extension products using another set of primers (LA primers) that each comprise another target-specific sequence. Such methods avoid barcode resampling and suppress primer dimers in traditional high multiplex PCR.
