  • Publication number: 20120077969
    Abstract: The present invention relates to a method for purifying a defined amount of nucleic acids from a nucleic acid-containing sample, which has at least the following steps: (a.) contacting the nucleic acid-containing sample with a defined amount of a nucleic acid binding phase with the following features: (i) the nucleic acid binding phase has nucleic acid binding ligands that have at least one protonatable group; (ii) the nucleic acid binding ligands are bound to a carrier; (iii) the nucleic acid binding phase has a surface with a low charge density, wherein the amount of nucleic acids in the sample exceeds the binding capacity of the amount of nucleic acid binding phase used; (b.) binding of the nucleic acids to the nucleic acid binding phase at a pH (binding pH) that is below the pKs value of at least one of the protonatable groups; (c.) elution of the nucleic acids at a pH that is above the binding pH, wherein a defined amount of nucleic acids is obtained.

  • Publication number: 20100273984
    Abstract: The invention relates to a method for enriching phosphopeptides. Said method is characterized in that a carrier is used which carries phosphate groups and/or phosphonate groups on the surface thereof. The phosphate groups and/or phosphonate groups are functionalized with zirconium ions and are bonded to the carrier by means of linker structures which have at least one alkyl chain containing at least 5 C atoms. Also disclosed are corresponding carriers and suitable kits for enriching phosphopeptides.
