    • The present invention relates to a method for the analysis of methylated cytosines in DNA. In the first step of the invention unmethylated cytosines in the DNA to be analysed are chemically converted into uracil while 5-methylcytosines remain unchanged. In a second step a methylation specific oligonucleotide carrying a non-extendable 3’ end is annealed to the converted DNA. Sub-sequently, the non-extendable 3’ terminus of the oligonucleotide is removed in case the oligonucleotide is bound to the DNA with the methylation status to be detected. Finally the unblocked oligonucleotide is extended, and the methylation status is concluded form the absence or presence of an extended oligonucleotide product. The method is preferably used for diagnosis and/or prognosis of adverse events for individuals, for distinguishing cell types and tissues, or for investigating cell differentiation.
    • 本发明涉及DNA分析甲基化胞嘧啶的方法。 在本发明的第一步中,待分析DNA中的未甲基化胞嘧啶化学转化成尿嘧啶,而5-甲基胞嘧啶保持不变。 在第二步中,携带不可延伸的3'末端的甲基化特异性寡核苷酸与转化的DNA退火。 接下来,在寡核苷酸与待检测甲基化状态的DNA结合的情况下,寡核苷酸的不可延伸的3'末端被去除。 最后,未阻断的寡核苷酸被延长,甲基化状态由延伸寡核苷酸产物的不存在或存在而结束。 该方法优选用于个体的不良事件的诊断和/或预后,用于区分细胞类型和组织,或用于调查细胞分化。

    • A method for determining a target nucleic acid sequence, wherein the target nucleic acid sequence is comprised in a preparation comprising a non-target nucleic acid sequence, the target nucleic acid sequence and the non-target nucleic acid sequence each having a first region of common sequence upstream of a first region of dissimilar sequence upstream of a second region of dissimilar sequence, the method comprising: (a) contacting the preparation with an oligonucleotide primer complementary to at least a portion of the first region of common sequence, under conditions to hybridise the primer thereto; (b) contacting the preparation with a first labelled nucleotide bearing a first label, wherein the first labelled nucleotide is complementary to a first template nucleotide comprised in the first region of dissimilar sequence of either the target nucleic acid sequence or the non-target nucleic acid sequence, under conditions to incorporate the first labelled nucleotide either into the primer hybridised to the target nucleic acid sequence or into the primer hybridised to the non-target nucleic acid sequence but not into both; (c) subjecting the preparation to a sequencing reaction, thereby extending the primer to form one or more first-labelled sequencing products comprising the first labelled nucleotide and one or more non-first-labelled sequencing products comprising no first labelled nucleotide; and (d) determining at least a portion of the sequence of the first-labelled sequencing products and/or the non-first-labelled sequencing products, thereby determining at least the second region of dissimilar sequence of the target nucleic acid sequence.
