  • Patent number: 9314454
    Abstract: The invention provides an orally disintegrating tablet containing (a) one or more saccharides or sugar alcohols selected from the group consisting of mannitol, lactose, xylitol, sucrose, erythritol and glucose and (b) low substituted hydroxypropylcellulose and substantially free of a starch disintegrant, which tablet is produced by steps of granulating a composition containing the above-mentioned components (a) and (b) by an agitation granulation method, and compression-molding the obtained granulation product. The invention also provides a method of producing an orally disintegrating tablet substantially free of a starch disintegrant, including steps of granulating a composition containing the above-mentioned components by an agitation granulation method, and compression-molding the obtained granulation product.

  • Patent number: 7125660
    Abstract: Methods for engineering a nucleic acid sensor molecule are provided. Biosensors comprise a plurality of nucleic acid sensor molecules labeled with a first signaling moiety and a second signaling moiety. The nucleic acid sensor molecules recognizes target molecules which do not naturally bind to DNA. Binding of a target molecule to the sensor molecules triggers a change in the proximity of the signaling moieties which leads to a change in the optical properties of the nucleic acid sensor molecules on the biosensor. Reagents and systems for performing the method are also provided. The method is useful in diagnostic applications and drug optimization.

  • Publication number: 20030087239
    Abstract: Methods for engineering a target activated biosensor are provided. Biosensors comprise a plurality of nucleic acid sensor molecules labeled with a first signaling moiety and a second signaling moiety. The nucleic acid sensor molecules recognizes target molecules which do not naturally bind to DNA. Binding of a target molecule to the sensor molecules triggers a change in the proximity of the signaling moieties which leads to a change in the optical properties of the nucleic acid sensor molecules on the biosensor.
