Abstract: The present invention relates to a method for inhibiting infection and reproduction of influenza type A WSN virus, which comprises providing an effective amount of a pharmaceutical composition; and contacting said composition with said influenza type A WSN virus, wherein said pharmaceutical composition contains C-phycocyanin (C-PC), allophycocyanin (APC), and spirulina growth factor (SGF). The present invention also provides a method for extracting said pharmaceutical composition, comprising the steps of: (a) adding hypotonic buffer solution to organic blue-green algae powder and mixing thoroughly; (b) incubating the mixture below room temperature overnight; (c) separating and purifying the mixture by a centrifuge; (d) collecting the suspending supernatant and detecting it by a spectrometer to determine ingredients and content; and (e) spray drying the supernatant; characterized in which low-temperature extraction is employed to maintain the bioactivity and nutrients of the pharmaceutical composition.

Abstract: This invention provides a method and a diagnostic kit that utilizes phycoerythrin to label tumor cells, wherein the high specificity and high affinity of phycoerythrin is to be used to label and enter tumor cells. With effective amount of phycoerythrin and suitable wavelength of light, the stimulated fluorescence from phycoerythrin can be used for tumor diagnosis.

Abstract: The present invention relates to an oral prophylactic agent against viral infection comprising water-soluble formula and/or enteric-coated formula, which includes ingredients selected from at least one of the group consisting of C-phycocyanin, allophycocyanin, spirulina growth factor, and combinations thereof.

Abstract: The present invention provides for several fluorescent labeling reagents and its kits that comprises B-phycoerythrin and other chemical fluorescent reagents that form a range of various fluorescence emission spectrums. The invented fluorescent labeling reagent can be used by itself or in conjunction with other kinds of reagents. When used by itself, one light source can output many kinds of fluorescent lights, making it useful in immunoassay, flow cytometry, and fluorescent light analysis.

Abstract: The invention provides a carrier for carrying radioactive substances and methods for using the same, wherein phycoerythrin is served as a carrier for carrying radioactive substances so as to enable accumulation of radioactive substances specifically in the tumor cells and the radiation emitted therefrom kills the tumor cells effectively. Therefore, the invention can be applied in the treatments for various types of cancers.
