  • Patent number: 11473134
    Abstract: A method for the deconvolution of nucleic acid-containing substance mixtures using synthetically generated target nucleotide sequences. Starting from a plurality of nucleotides,, a plurality of different target nucleotide sequences (TNS) is generated according to a predetermined algorithm. At least one of the TNS generated is associated with at least one substance or substance combination and chemically coupled thereto. At least one substance mixture to be analysed and having at least two different TNS is provided and is sequenced according to a sequencing method., at the same time all TNS contained in the substance mixture are detected in a common sequence spectrum. To facilitate the deconvolution, the sequence spectra of a substance mixture should be deducted/subtracted from each other prior to and after a selection experiment.

  • Patent number: 10527612
    Abstract: In a method and arrangement for detecting binding events of molecules, at least one second molecule covalently bound to a ligand, and optionally bonded to a third molecule bound to a ligand, forms a specific non-covalent fond with a first molecule immobilised on a bioactive surface by a covalent bond, and binding events between an analyte molecule and the second-molecule bound ligand are detected by an analytical measuring method, wherein the specific non-covalent bond between the first and second molecules is breakable by supplying a buffer solution, and, hence, a specific ligand, or two, different specific ligands are made available on the bioactive surface in an easily reversible manner.

  • Publication number: 20170088814
    Abstract: A physical self-organizing hydrogel system for biotechnological applications composed of a non-covalent network on the basis of a protein-ligand interaction includes a tetrameric protein and biotin or a derivative thereof as a ligand, wherein biotin or derivative is covalently conjugated to an end of a polymer chain or a linear or multi-arm synthetic polymer of a single-or double-strand oligonucleotide and wherein the solid content in relation to the entire hydrogel is at least 3% and the conjugates are crosslinked by the tetrameric protein. A mixture ratio is a molar equivalent ratio between the protein and the number of terminal biotinylated ends of the polymer chains in the biotin-polymer conjugate of 1:2 to 1:8. The hydrogel formation occurs with controlled kinetics on the basis of protein-ligand interaction.
