  • Patent number: 10407713
    Abstract: The present invention provides a special reagent for the pretreatment of sample materials. The pretreatment with the reagent according to the invention enables the isolation of nucleic acids by a uniform method from very diverse sample materials, in particular different bioprocess samples, even if the nucleic acids are only present in small amounts in the sample materials. The reagent used for the pretreatment comprises, as key component, at least one compound comprising an amino group. The invention further relates to methods of purification of nucleic acids, in which the sample material is pretreated correspondingly, and suitable kits.
    Type: Grant

  • Patent number: 10011826
    Abstract: The present invention relates to a method of isolating/extracting in parallel various biomolecules, in particular nucleic acids and proteins, from the same fixed biological samples, to the quantification and analysis of the biomolecules isolated by the method of the invention, and to a kit for isolating/extracting in parallel various biomolecules from a fixed sample, to the use of said kit for diagnosing, prognosing, deciding the therapy of and monitoring the therapy of a disease.
