  • Patent number: 11154864
    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.

  • Patent number: 11104896
    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.

    Abstract: The present invention pertains to a method for isolating extracellular nucleic acids from a sample, wherein said sample is optionally stabilized, by binding the extracellular nucleic acids to a solid phase which carries anion exchange groups, comprising the following steps: a. binding the extracellular nucleic acids to the solid phase in a binding mixture having a first pH which allows binding the extracellular nucleic acids to the anion exchange groups of the solid phase; wherein the sample makes up at least 85% of the volume of the binding mixture; b. separating the solid phase with the bound extracellular nucleic acids; c. optionally washing the extracellular nucleic acids; d. optionally eluting extracellular nucleic acids from the solid phase. The method has the advantage that large sample volumes can be processed and that extracellular nucleic acids can be isolated rapidly with a high yield. The method is particularly suitable for automatable processes.
