  • Publication number: 20220307063
    Abstract: A method for analyzing a microbiota, comprising (1) dissolving a probe capable of non-specifically interacting with a plurality of microorganisms in a plurality of solvents having different ionic strengths and pH levels, wherein the probe comprises: (a) a cationic polymer and (b) an environment-sensitive fluorophore; (2) adding a test sample containing the microbiota to a plurality of probe solutions prepared in the step (1), thereby microorganisms in the test sample and the probe are interacted non-specifically; (3) measuring fluorescence intensities of the plurality of probe solutions to which the test sample has been added in the step (2); and (4) comparing the pattern of fluorescence intensities obtained in the step (3) with the pattern of fluorescence intensities obtained from a reference sample.

  • Patent number: 10711273
    Abstract: Provided is a method for synthesizing a protein, into which a nucleobase amino acid (NBA) is introduced at a desired position, that comprises: a step for preparing mRNA into which a modified codon is inserted at a desired position downstream of an initiation codon; and a step for translating the aforesaid mRNA into a protein in the presence of tRNA, said tRNA recognizing the modified codon and being acylated with the NBA. Also provided is a ribozyme that catalyzes the aminoacylation of tRNA and comprises two RNA molecules.
