  • Patent number: 8518859
    Abstract: Provided is a method of increasing a yield of a staple food crop which comprises bringing a compound represented by the following Formula (I) into contact with a plant body, excluding seeds, of a staple food crop to be cultured. The staple food crop is preferably a cereal crop, a tuber crop or the like. In the following Formula (I), R1 and R2 each independently represent a hydrogen atom or a monovalent substituent, or R1 and R2 are bound together to form an azo group; and R3 represents a hydrogen atom or a monovalent substituent.

  • Patent number: 8461305
    Abstract: Disclosed is a novel lectin which can bind specifically to an L-fucose ?1?6 sugar chain. Also disclosed is use of the lectin. The L-fucose ?1?6 specific lectin of the present invention is characterized in that: (1) the lectin is extracted from a basidiomycete or an ascomycete; (2) the lectin has a molecular weight by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of 4,000 to 40,000; and (3) the lectin has an affinity to an L-fucose ?1?6 sugar chain, the affinity being represented by an association constant of 1.0×104M?1 or more (at 25 degrees C.). The lectin can be used for detecting an L-fucose ?1?6 sugar chain specifically, and is effective for the purification of an L-fucose ?1?6 sugar chain or a non L-fucose ?1?6 sugar chain.
