  • Publication number: 20160327571
    Abstract: The present invention provides methods, compositions, apparatus, and kits for assessing glycoforms of proteins as a biomarker for disease. A purified recombinant form of lectin is used as a detector molecule to specifically label target sugars expressed in disease states. The high affinity of recombinant lectin allows for automation of assays that would be used in the diagnosis of diseases such as, but not limited to, cancer or liver disease.

  • Patent number: 9168260
    Abstract: The present invention describes a unique antiviral screen system. The assay is based on quantitatively monitoring viral activation of host cell beta-interferon (IFN-?) gene expression in a HEK293-derived reporter cell line expressing a firefly luciferase gene under the control of a human IFN-? promoter. Unlike the traditional high throughput antiviral assays that measure either the reduction of viral components/yields or cytopathic effect, the readout of the reporter assay in the present invention is the virus-induced host cellular innate immune response. Hence, the assay allows for identification of compounds that inhibit virus infection. In addition, because induction of IFN is one of the most common attributes of viruses, the assay is applicable to all the viruses that are able to infect the reporter cell line and induce IFN-? expression.
