  • 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. The methods output two separate libraries from DNA and RNA, respectively, which helps flexible manipulation on downstream sequencing platforms. The application also claims the DNA library and the cDNA library produced by the method and the DNA tag and the RNA tag used in the method.

  • Patent number: 12031125
    Abstract: The present invention pertains to methods and kits for isolating extracellular nucleic acids from a biological sample using anion exchange particles. It was found that incorporating into the binding mixture a polyoxyalkylene fatty alcohol ether compensates performance variations that are attributable to differences in the anion exchange surface as they may occur e.g. between different lots/batches of the anion exchange particles and/or during storage of said particles. Moreover, including a polyoxyalkylene fatty alcohol ether in the binding mixture resulted in a higher purity of the obtained eluates revealing significantly less inhibition in a downstream reaction such as a PCR reaction.

  • Patent number: 11819851
    Abstract: A microfluidic device with a microfluidic circuit including an array of fluidly coupled microchambers. Each microchamber includes a reaction chamber and an associated vent chamber. The microfluidic circuit may be arranged so that a fluid sample introduced to microfluidic device flows into the reaction chamber and air or other gas present in the reaction chamber is vented from the microchamber through the vent chamber. The microchamber may be configured to allow only the flow of air into the vent chamber from the reaction chamber until the air has been displaced from the reaction chamber by the fluid sample and/or a predefined volume of the fluid sample has been received in the reaction chamber. The microchamber may be further configured to release the fluid sample to thereafter flow from the reaction chamber into the vent chamber.
