  • Publication number: 20160017314
    Abstract: Methods are disclosed for isolating nucleic acids from formalin-fixed paraffin embedded (FFPE) tissue samples. Each of tissue samples contains paraffin and a target biological tissue or material, and the method includes the steps of: adding a first reagent and a second reagent to the FFPE tissue sample, the first reagent dissolving the paraffin material and the second reagent lysing the biological tissue; mixing the first reagent, the second reagent, and the FFPE tissue sample to form a first mixture; (2) heating the first mixture at 50-80° C. for 30-90 minutes; and then heating the first mixture at 80-95° C. for 30-90 minutes to fractionize the first mixture to form an aqueous phase and an oil phase; (3) collecting an aqueous solution from the aqueous phase; and (4) isolating nucleic acids from the aqueous solution. The method improves the efficiency and convenience of isolating nucleic acids from FFPE tissue samples.

  • Patent number: 8663582
    Abstract: An integral-type reaction cartridge includes a plurality of reaction containers and at least a separation container. The plural reaction containers and the separation container are integrally formed of plastic and lined along a first direction. The separation container has a first end, a second end opposing the first end, and a hollow accommodating space between the first and second ends, wherein the first end is an open end, the second end is a closed end, and the accommodating space tapers from the first end to the second end. The accommodating space has a first side and a second side along the first direction, as well as a third side and a fourth side along a second direction perpendicular to the first direction. Near the second end, at least one of the first side and the second side has a greater slope than the third side and the fourth side.

  • Patent number: 8513405
    Abstract: Disclosed are a chaotropic agent; a reagent including a chaotropic agent and a lithium salt; a reagent kit including a chaotropic agent; a chaotropic agent, a reagent, a reagent kit, and a method for isolating a nucleic acid by use of a magnetic cellulose material; a method for binding a nucleic acid to a magnetic cellulose material; a method for isolating a nucleic acid; and a method for purifying a chromosome DNA. It is required that each of the chaotropic agents, the reagents, and the reagent kits works with at least one solid-phase, magnetic cellulose-containing carrier to isolate a nucleic acid from non-nucleic acid substances. In addition, each chaotropic agent includes an alcohol substance and a substrate solution for adjusting the alcohol substance to an appropriate concentration and thereby promoting binding of the nucleic acid in a sample to the magnetic cellulose.

  • Patent number: 8163519
    Abstract: The invention relates to an improved nucleic acid molecule encoding fungal immunomodulatory protein (FIP) that is better expressed in fungi, to vectors comprising the nucleic acid molecule, to hosts transformed with said vectors, to processes of expressing the protein of the invention in said transformed hosts, to the protein of the invention produced by said processes, to uses of said hosts comprising the protein of the invention and to a process of purifying FIP. The protein of the invention has wide immunomodulatory activity. Thus, the present invention further relates to uses of the protein of the invention in cosmetic or pharmaceutical compositions and to food or feed additives comprising the protein of the invention. Finally, the invention relates to the method of modulating immunological activities by orally administering FIP or proteins fused with FIP to a subject.
