    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.

    摘要: A process for amplifying any target nucleic acid sequence contained in a nucleic acid or mixture thereof comprises treating separate complementary strands of the nucleic acid with a molar excess of two oligonucleotide primers and extending the primers with a thermostable enzyme to form complementary primer extension products which act as templates for synthesizing the desired nucleic acid sequence. The amplified sequence can be readily detected. The steps of the reaction can be repeated as often as desired and involve temperature cycling to effect hybridization, promotion of activity of the enzyme, and denaturation of the hybrids formed.

    摘要: Single or multiple nucleotide variations in nucleic acid sequence can be detected in nucleic acids by a process whereby the sample suspected of containing the relevant nucleic acid is repeatedly treated with primers, nucleotide triphosphates, and an agent for polymerization of the triphosphates and then denatured, in a process which amplifies the sequence containing the nucleotide variation if it is present. In one embodiment, the sample is spotted on a membrane and treated with a labeled sequence-specific oligonucleotide probe. Hybridization of the probe to the sample is detected by the label on the probe.

    摘要: In a method for detecting the presence or absence of a specific restriction site in a nucleic acid sequence an oligonucleotide probe complementary to one strand of the nucleic acid sequence spanning said restriction site is synthesized. The probe is labeled at the end nearer the restriction site. The nucleic acid is hybridized to the probe and a blocking oligomer may be added, if necessary, to prevent non-specific binding of the probe. Subsequent digestion with a restriction enzyme cleaves those oligomers that have hybridized to the nucleic acid and reformed the restriction site. The resulting cut and uncut labeled oligomers are separated and detected based on the type of probe label.The described method may be used to detect sickle cell anemia.
