  • Publication number: 20140199303
    Abstract: The present invention relates to a stable liquid formulation of etanercept (recombinant p75 sTNFR:Fc fusion protein), and more particularly, to a liquid formulation comprising one or more stabilizers selected from the group consisting of methionine, lysine, histidine, and pharmaceutically acceptable salts thereof in an amount sufficient to reduce by-product formation of etanercept during storage. The liquid formulation according to the present invention effectively reduces production of etanercept by-products and to stably maintain its pharmaceutical efficacies for long-term storage. Therefore, the reconstitution procedure is not required before administration, and the sterile formulation can be administered to patients to ensure patient safety. Thus, it can be applied to the fields in need of etanercept treatment.

  • Publication number: 20140127671
    Abstract: The present invention relates to a kit for simultaneous diagnosis of viral respiratory diseases. To be more specific, the present invention is directed to a method for diagnosing viral respiratory diseases by detecting the genes specific to the respiratory disease-causing virus, a primer set for diagnosing the viral respiratory diseases used in the diagnosis method, a composition for simultaneous diagnosis of viral respiratory diseases, comprising the primer set, and a kit for simultaneous diagnosis of viral respiratory diseases, comprising the composition. When the primer set of the present invention for diagnosing the viral respiratory diseases is used, 14 different types of respiratory viruses can be simultaneously detected only with one reaction through real-time multiplex reverse transcription (RT)-PCR, and the onset of respiratory diseases caused by these viruses can be diagnosed. Thus, the primer set of the present invention can be widely used for prompt diagnosis and treatment of respiratory diseases.
