Patents by Inventor Jan Di KIM

Jan Di KIM has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220205016
    Abstract: The present invention relates to a molecular diagnostic method using a cell lysis composition for nucleic acid extraction, and particularly, to a molecular diagnostic method using a cell lysis composition for nucleic acid extraction, which may minimize the time for molecular diagnosis by performing a polymerase chain reaction on a mixture containing both Tween 20 as a component for nucleic acid extraction and a PCR buffer necessary for performing the polymerase chain reaction, without a separate nucleic acid extraction process, and reduce the cost of molecular diagnosis by minimizing the use of dedicated devices and consumables in extraction.

  • Patent number: 10695279
    Abstract: The present invention provides a peptide having skin-whitening activity. The peptide of the present invention exhibits an excellent skin whitening effect by inhibiting melanogenesis, inhibiting the activity of tyrosinase, inhibiting the expression of melanosis-involved factors, and inhibiting melanosome transfer. The peptide of the present invention has excellent skin permeability due to the small size thereof. Excellent activity and stability of the foregoing peptide of the present invention can be very favorably applied to cosmetics.

  • Patent number: 10526373
    Abstract: The present invention provides a peptide which shows a melanin generation-promoting activity. The peptide of the present invention increases the activity and expression of tyrosinase and increases the expression of factors related to melanin generation, thereby showing an excellent effect in melanin generation. The peptide of the present invention can be used for preventing, alleviating, and treating hypomelanosis. The above-mentioned superior activity and stability of the peptide of the present invention allows the peptide to be very favorably applied to medicines, quasi drugs, and cosmetics.
