  • Patent number: 10545152
    Abstract: A method (e.g. high resolution melting analysis) of determining of the presence or absence of a target nucleic acid in a sample, e.g. a biological sample, the method comprising steps of:?(a) contacting the sample with a composition comprising?(i) a quaternary ammonium compound, e.g. 3-(trimethoxysilyl) propyl-dimethyl octadecyl ammonium chloride (3-TPAC) or a precursor thereof, in order to release the nucleic acids from said sample; and?(b) contacting the sample with a probe which is capable of interacting with the nucleic acid sequence; and?(c) observing and/or measuring a property of the sample, e.g. fluorescence from a dsDNA binding dye.

  • Patent number: 10364427
    Abstract: There is described a method of extracting DNA and/or RNA from a cell or capsid, the method comprising contacting the cell or capsid with a composition comprising a quaternary ammonium compound including a silicon-containing functional group. The quaternary ammonium compound may be of general formula (I) or a derivative salt thereof wherein L is a linking group; each of R1, R2, R3, R4, R5 and R6 is independently selected from H or an optionally substituted alkyl, alkenyl, aryl or alkoxy group; and n is 0 or 1. A PCR promoting agent may be provided. The method may be one of 1 detecting and/or diagnosing a disease or medical condition.
