  • Patent number: 11434527
    Abstract: The present invention provides a method for detecting mycoplasma, which can directly confirm whether a cell is infected with mycoplasma, by simultaneously amplifying DNA extracted from lysing a host cell infected with mycoplasma, and mitochondrial DNA in the cytoplasm of the host cell. According to the method of the present invention, by directly using the DNA inside the host cell, the DNA of mycoplasma bound around the nucleus of the host cell can be used as an amplification target, thereby increasing detection sensitivity. In addition, since the mitochondrial DNA inside the host cell is used as an amplification target of an internal control sample, whether the sample has been sampled in an appropriate amount can be confirmed in a convenient manner, and furthermore, by comparing the band size between the internal control sample and the mycoplasma DNA, the degree of mycoplasma infection can be quantitatively confirmed.

  • Patent number: 8623348
    Abstract: Disclosed is an interferon-? (IFN-?) fused protein having IFN-? fused to a cytoplasmic transduction peptide (CTP). The disclosure relates to a fused protein wherein a CTP, which binds well to cell-membrane barriers and enables translocation into the liver, is genetically fused to a human IFN-?, thereby enhancing the conjugation capacity of cell membranes and antiviral activity, inhibiting CTP transport into the cell nucleus, and enhancing the translocation and settlement of the fused protein into the liver and of transduction to the liver tissue. Accordingly, it is possible to develop protein-based medicines effective for preventing or treating various liver diseases associated with viral infection at low doses.
