    摘要: The present invention provides a process for detecting the presence or absence of at least one specific nucleic acid sequence in a sample or distinguishing between two different nucleic acid sequences in said sample, wherein each nucleic acid sequence to be detected consists of two separate strands, which process comprises amplifying the specific sequence or sequences (if present) by
    (a) treating the sample with one oligonucleotide primer for each of the two strands of each different specific nucleic acid sequence being detected under hybridizing conditions such that for each strand of each different sequence being detected an extension product of each primer is synthesized which is complementary to each nucleic acid strand, wherein said primers are selected so as to be substantially complementary to each strand of each specific sequence such that the extension product synthesized from one primer, when it is separated from its complement, serves as a template for synthesis of an extension product of the other primer; (b) treating the product of step (a) under denaturing conditions to separate the primer extension products from their templates; (c) treating the product of step (b) with oligonucleotide primers such that a primer extension product is synthesized using each of the single strands produced in step (b) as a template; and detecting the thus amplified sequence or sequences (if present).

    摘要: The invention provides a group of oligonucleotide probes in which the individual probes are capable of hybridizing to specific gene sequence variations so as to permit detection of said variations when said probes are labelled and so-hybridized, whereby allelic variations and gene polymorphism in samples may be detected using said group of probes. Such probe groups are useful for detecting nucleotide variations, mutations and polymorphisms by hybridization to amplified nucleic acid sequence containing such variations, mutations or polymorphisms.

    摘要: The invention provides an oligonucleotide primer exhibiting complementarity to an end of a nucleic acid sequence corresponding to a second exon sequence in an HLA Class II gene, wherein said primer can be hybridized to said sequence and then extended thereon to produce a single stranded extension product which includes a sequence complementary to said second exon sequence. Such primers can be used in a nucleic acid amplification process to enable detection of gene variations or polymorphism. For detection purposes, the invention also includes an oligonucleotide probe that is capable of hybridizing to a sequence in the second exon of an HLA Class II gene so as to permit detection of said sequence when said probe is labelled as so-hybridized.

    摘要: The present invention is directed to a process for amplifying and detecting any target nucleic acid sequence contained in a nucleic acid or mixture thereof. The process comprises treating separate complementary strands of the nucleic acid with a molar excess of two oligonucleotide primers, extending the primers to form complementary primer extension products which act as templates for synthesizing the desired nucleic acid sequence, and detecting the sequence so amplified. The steps of the reaction may be carried out stepwise or simultaneously and can be repeated as often as desired. In addition, a specific nucleic acid sequence may be cloned into a vector by using primers to amplify the sequence, which contain restriction sites on their non-complementary ends, and a nucleic acid fragment may be prepared from an existing shorter fragment using the amplification process.
