Method for detecting a nucleotide sequence

摘要

A method is disclosed for detecting a nucleotide sequence by a polymerase chain reaction, the nucleotide sequence is a constituent of a double-stranded nucleic acid molecule which is in solution and formed of a strand and a counter-strand. A first primer is added to the solution and is complementary to a first segment of the strand located at the 5'-terminus of a central segment. A second primer is added and is complementary to a 5'-terminal second segment of the counter-strand. The solution is brought into contact with a third primer whose 5'-terminal end is bound to a solid phase. The third primer is complementary to the central segment of the strand containing the nucleotide sequence. A reaction vessel is closed which contains the solution. The solution is repeatedly heated and cooled and the nucleic acid molecule is detected in the closed reaction vessel.
