  • Kits for detecting a target nucleic acid with blocking oligonucleotides
    Patent number: 5712386
    Abstract: A method for detecting a target nucleic acid, which method includes the steps of (i) amplifying the target nucleic acid to obtain an amplification product using a polymerase, a first primer with or without a segment noncontiguous to a first priming sequence, and a second primer with or without a segment noncontiguous to a second priming sequence in the presence of an oligonucleotide which is incapable of acting as a primer for the polymerase, wherein the oligonucleotide has at least 5 consecutive nucleotides fully complementary to at least 5 consecutive nucleotides of the first primer; and (ii) detecting the presence of the target nucleic acid by monitoring the amplification thereof.
    Type: Grant
    Filed: May 4, 1995
    Date of Patent: January 27, 1998
    Assignee: Biotronics Corporation
    Inventors: Chang-Ning J. Wang, Kai-Yuan Wu
