Patents by Inventor Katrina Felicia Tjhung

Katrina Felicia Tjhung 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).

  • Method for detecting a substance in a sample using modified bacteriophages
    Patent number: 10900061
    Abstract: The present invention provides a binding assay that employs an activatable dormant bacteriophage carrying a reporter gene to qualitatively or quantitatively detect the presence of a substance of interest in a sample. Also provided is a simple culture device that is designed for manufacture and use in areas of limited resources. The device is useful for cell culture in such environments with limited resources because cells grow in paper just as they do in a culture dish.
    Type: Grant
    Filed: March 10, 2017
    Date of Patent: January 26, 2021
    Inventors: Ratmir Derda, Maribel Elizabeth Funes Huacca, Simon Ng, Katrina Felicia Tjhung
  • Genetic encoding of chemical post-translational modification for phage-displayed libraries
    Patent number: 10724034
    Abstract: The present application provides a method of synthesizing a genetically-encoded chemical modification of a peptide library. A vector in a substrate, such as a phage, is modified to include a peptide linker and a modification to form a genetic “barcode”. The barcode is screened against potential targets which may be used in drug discovery.
    Type: Grant
    Filed: October 22, 2015
    Date of Patent: July 28, 2020
    Inventors: Ratmir Derda, Pavel Kitov, Simon Ng, Katrina Felicia Tjhung, Daniel Ferrer Vinals
