Abstract:
Novel dipeptide ethers are effective for lowering blood glucose, serum insulin, free fatty acids, cholesterol and triglyceride levels. The dipeptide ethers are also useful for the treatment and/or prophylaxis of diabetes, obesity, inflammation and autoimmune diseases such as multiple sclerosis and rheumatoid arthritis.
Abstract:
The present invention describes methods of detecting a nucleic acid in a sample, based on the use of terminal-phosphate-labeled nucleotides as substrates for nucleic acid polymerases. The methods provided by this invention utilize a nucleoside polyphosphate, dideoxynucleoside polyphosphate, or deoxynucleoside polyphosphate analogue which has a colorimetric dye, chemiluminescent, or fluorescent moiety, a mass tag or an electrochemical tag attached to the terminal-phosphate. When a nucleic acid polymerase uses this analogue as a substrate, an enzyme-activatable label would be present on the inorganic polyphosphate by-product of phosphoryl transfer. Cleavage of the polyphosphate product of phosphoryl transfer via phosphatase leads to a detectable change in the label attached thereon. When the polymerase assay is performed in the presence of a phosphatase, there is provided a convenient method for real-time monitoring of DNA or RNA synthesis and detection of a target nucleic acid.
Abstract:
The present invention relates to a novel set of four fluorescently labeled dye terminators. Two of them are single dye labeled terminators and the other two dye terminators are based on fluorescent resonance energy transfer (FRET). The FRET dye terminators are generated from the 4′,5′-bis-aminomethylfluorescein. Of the two amino groups of the donor dye, 4′,5′-bis-aminomethylfluorescein, one amino group is used to attach the acceptor dye, and the other amino group is used to attach the dideoxynucleoside-5′-triphosphate. Their preparation, energy transfer efficiency, and use as labels, specifically, in DNA sequencing reactions is disclosed.
Abstract:
The present invention relates to a tissue culture process for producing a large number of viable mint plants in vitro. The process of the present invention employs specified pieces of an internodal segment of the stem of the mint plant as the starting material and identifies medium and culture conditions for producing a large number of plants. Such plants can be used for micropropagation, selection of mutants, production of plants with altered levels of endogenous secondary metabolites and for genetic engineering.
