ShaMay Tang 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).

  • Kit for protein S functional assay
    Patent number: 8334108
    Abstract: The invention relates generally to a new functional protein S assay and kit that is based on the ability of endogenous protein S to prolong clotting time. In the assay procedure, a test plasma sample is diluted with protein S deficient plasma, followed by the addition of purified or recombinant tissue factor (pTF or rTF), purified natural or synthetic phospholipid (pPL or sPL) and activated protein C (APC) or protein C activator (PCA). The clotting time is then measured and compared to a standard curve or a normal control.
    Type: Grant
    Filed: November 19, 2008
    Date of Patent: December 18, 2012
    Assignee: Instrumentation Laboratory Company
    Inventors: Yong Dai, Biqing Ye, Kui Chen, Pau Bruguera, Daniel Lawson, Shamay Tang
