  • Agent for protein precipitation, a method of protein precipitation, a method of protein assay using protein precipitation agent, and a kit for protein assay
    Patent number: 6875617
    Abstract: A method of protein precipitation, concentration and removal of non-protein agents from the protein solution wherein the protein solution is treated with a protein-precipitation agent containing an acidic agent, a salt and a precipitate forming agent. After precipitation, the protein precipitate is washed with a water miscible organic solvent agent to remove non-protein agents present in the protein precipitate.

  • Agent for protein precipitation, a method of protein precipitation, a method of protein assay using protein precipitation agent, and a kit for protein assay
    Patent number: 5900376
    Abstract: A method of a protein assay wherein a protein solution is treated with an acidic component followed by the addition of a precipitate-forming component, which results in precipitation of protein. The protein precipitate is collected and treated with one or more reagents of a protein assay to produce a characteristic protein color reaction. The concentration of protein is determined by measuring the optical density of protein color reaction and comparing the color reaction with a known standard.

  • Method, device, and kit for total nucleic acid assay
    Patent number: 5843662
    Abstract: A method, device and a kit for determining total nucleic acid concentration in a nucleic acid solution, which comprises applying the nucleic acid solution to a nucleic acid-support capable of retaining the total nucleic acid in the form of a nucleic acid spot having a size that is proportional to the nucleic acid concentration; measuring the size of the nucleic acid spot produced on the nucleic-support; and comparing the size of the nucleic acid spot with a standard.
