    • A method for determining the methylation status of a potential methylation site in genomic nucleic acid comprising treating genomic nucleic acid with an agent which modifies cytosine bases but does not modify 5­methyl-cytosine bases under conditions to form a. modified nucleic acid template containing a potential methylation site; providing a first clamp containing a first capture sequence complementary to a region flanking one side of the potential methylation site in the modified nucleic acid template, providing a second clamp containing a second capture sequence complementary to a region flanking the other side of the potential methylation site in the modified nucleic acid template; allowing the first clamp and the second clamp to hybridise to the modified nucleic acid template; ligating the hybridised first and second clamps to form a probe spanning the potential methylation site in the modified nucleic acid template; digesting the modified nucleic acid template to obtain the probe; and detecting the probe and determining the methylation status of the potential methylation site in the modified genomic nucleic acid.

    • The present invention provides derivatives or modified nucleic acid sequences of several microorganisms for use in the detection and analysis of said microorganisms. The derivative nucleic acids contain the bases adenosine (A), guanosine (G), T (thymine) and U (uracil or some other non-A, G or T base or base-like entity). Given that microbial nucleic acids do not contain methylated cytosine (C) or other C alterations, all C are converted to U. These sequences are amplified where the U in the derivative nucleic acid is replaced by a T, resulting in a modified sequence with the same number of total bases as the corresponding unmodified microbial nucleic acid sequence but made up of a combination of three bases only: A, G and T. As a consequence of this process the nucleic acids derived from the upper and lower strands of the original dsDNA are no longer complementary and the modified microbial sequences have reduced relative genomic complexity for use in detection and analysis of microorganisms.
    • 本发明提供用于检测和分析所述微生物的几种微生物的衍生物或修饰的核酸序列。 衍生的核酸含有腺苷(A),鸟苷(G),T(胸腺嘧啶)和U(尿嘧啶或其他非A,G或T碱基或碱基类实体)。 鉴于微生物核酸不含甲基化胞嘧啶(C)或其他C改变,所有C转化为U.这些序列在衍生核酸中的U被T代替时被扩增,导致修饰的序列与 与相应的未修饰微生物核酸序列相同数量的总碱基,但由三个碱基的组合组成:A,G和T.作为该方法的结果,源自原始dsDNA的上部和下部链的核酸 不再互补,修饰的微生物序列降低了用于微生物检测和分析的相对基因组复杂性。

    • The invention provides methods for treating nucleic acid, particularly nucleic acid that is methylated. In one embodiment, the method can include the steps of (a) providing a denaturing environment to a nucleic acid sample; (b) reacting the nucleic acid sample with a bisulphite reagent and incubating the reaction so as to form a treated nucleic acid sample where methylated nucleotides in the nucleic acid sample remain unchanged while unmethylated nucleotides are converted to another form; (c) diluting the treated nucleic acid sample so as to reduce salt concentration to a level which will not substantially interfere with a nucleic acid precipitating step; (d) precipitating the diluted treated nucleic acid to substantially remove any unwanted reagents or diluents from treated nucleic acid; and (e) carrying out de-sulphonation of the precipitated treated nucleic acid so as to remove sulphonate groups present on the treated nucleic acid so as to obtain a nucleic acid sample substantially free of sulphonate groups.
