  • Publication number: 20130041142
    Abstract: [Object] An object of the present invention is to provide a human sweet taste receptor-acting sweet taste regulating substance to a sweet taste substance by which the advantageous effects such as improvement in a taste, saving of a sweetener, reduction in calorie, low caries etc. can be obtained by applying to various foods and beverages. [Solution] The sweet taste receptor-acting sweet taste regulating substance of the present invention is identified by measurement of a physiological response by a sweet taste substance, using a cultured cell strain which is allowed to express hT1R2 and hT1R3, and a G protein ? subunit, by transferring an expression construct obtained by inserting respective cDNAs encoding the hT1R2 and the hT1R3, and the G protein ? subunit into the same plasmid, into a 293 cell in which an FRT (Flippase Recognition Target) site has been incorporated into one place in a genome DNA.

    Abstract: The present invention describes a class of dyes for use in staining cell samples and methods of making such dyes. A preferred class of dyes known as detergent dyes which possess the ability to stain cells in whole blood and are only slowly leached or lost from the stained cells over time are described. The present invention has application, for example, to blood typing for the determination of the presence of blood group antigens A, B, AB, O, and D (Rh.sub.o) and antibodies to such antigens.
