Chatchai Tayapiwatana 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).

  • Process of screening for alpha-thalassemia carrier using immunochromatographic strip test
    Patent number: 8563330
    Abstract: The invention provides a device and method for the rapid identification of patients suspected of having thalassemia. The invention provides a test strip for the aqueous detection of thalassemia related proteins in whole blood. The test strip includes antibodies specific to the gamma 4, (?4) protein and provides easy visual discrimination between a positive result and a negative result. The invention can be used in remote or clinical settings.
    Type: Grant
    Filed: March 21, 2008
    Date of Patent: October 22, 2013
    Assignee: National Science and Technology Development Agency
    Inventors: Watchara Kasinrerk, Chatchai Tayapiwatana, Thanusak Tatu, Suthat Fucharoen, Sawitree Chiampanichayakul
  • Methods for large scale production of recombinant DNA-derived tPA or K2S molecules
    Patent number: 7462476
    Abstract: The invention belongs to the field of thrombolysis and of tissue plasminogen activator (tPA) derivative production in prokaryotic cells. The invention relates to methods for the production of a recombinant DNA-derived tPA, a variant thereof or a (Kringle 2 Serine) K2S molecule or a variant thereof in prokaryotic cells, wherein the tPA or K2S or variant is secreted extracellularly as an active and correctly folded protein, and the prokaryotic cell contains and expresses a vector comprising the DNA coding for the tPA or K2S or variant operably linked to the DNA coding for the signal peptide OmpA. The invention further relates to specific K2S derivatives obtainable by the method. The invention further relates to the DNA molecules and the use of the DNA molecules in the methods.
