Conrad Leung 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).

  • Patent number: 9441271
    Abstract: This disclosure provides methods and compositions for amplification and sequencing of DNA templates, comprising at least two of: 2?-deoxyinosine-5? triphosphate, 5-propynyl-2?-deoxycytidine-5?-triphosphate, and 8-oxo-2?-deoxyguanosine-5?-triphosphate. Incorporation of these promoting nucleotides into amplification and sequencing reactions improves the amplification and sequencing of difficult-to-sequence DNA regions such as a GC rich regions or GT rich regions; repetitive sequences, including dinucleotide, trinucleotide, direct, inverted, Alu, poly A or poly T repeats; and hairpin or other secondary structures.
    Type: Grant
    Filed: June 1, 2015
    Date of Patent: September 13, 2016
    Assignee: GENEWIZ INC., SUZHOU
    Inventors: Shihong Li, Narisra Jongkam, Shifang Zhang, Conrad Leung

  • Patent number: 8420341
    Abstract: This invention relates to assays for detecting and measuring ADP. In particular, this invention provides homogeneous luminescent assays that detect ADP generation and measures ADP accumulation based on enzymatic coupling reactions. The assays of the present invention can be applied to all types of kinases and other ADP-generating enzymes, are antibody free, beads free, radioisotope free, and compatible with commonly used kinase buffers.
