Process for the measurement of nucleic acids
First Claim
1. A process for detecting the existence of at least two target polynucleotide sequences of oligonucleotide analytes in a nucleic acid sample, comprising the steps of;
- (a) mixing said nucleic acid sample with a labeled first common polynucleotide, and a second polynucleotide as a probe which is hybridizable with a first target polynucleotide sequence of oligonucleotide and with the labeled first common polynucleotide, to detect the existence of the first target polynucleotide sequence of oligonucleotide; and
(b) mixing said nucleic acid sample with the labeled first common polynucleotide used in step (a) for detecting said first target polynucleotide sequence of oligonucleotide, and a third polynucleotide as a probe which is hybridizable with a second target polynucleotide sequence of oligonucleotide and with the labeled first common polynucleotide, to detect the existence of the second target polynucleotide sequence of oligonucleotide.

Abstract
A process for detecting the existence of at least one sequence of oligonucleotide in a nucleic acid sample includes at least one performance of a step of mixing the sample with
a labeled common polynucleotide, and
a polynucleotide probe comprising a sequence complementary to at least a part of the sequence of oligonucleotide and a sequence complementary to at least a part of the labeled common polynucleotide. The existence of a sequence of oligonucleotide which is an analyte existing in a nucleic acid sample can be detected by the use of a common reagent and an unattached polynucleotide having a base sequence specific for the analyte to be measured.

3. A process for detecting the existence of at least two target polynucleotide sequences of oligonucleotide analytes in a nucleic acid sample, comprising the steps of:
-
(a) mixing said nucleic acid sample with a labeled first common polynucleotide, a second polynucleotide as a probe which is hybridizable with a first target polynucleotide sequence of oligonucleotide and with the labeled first common polynucleotide, a third common polynucleotide attached to a solid phase and which is selected without regard to said first target polynucleotide sequence of oligonucleotide, and a fourth polynucleotide as a probe which is hybridizable with said first target polynucleotide sequence of oligonucleotide and with the third common polynucleotide attached to the solid phase, to detect the existence of the first target polynucleotide sequence of oligonucleotide; and (b) mixing said nucleic acid sample with the labeled first common polynucleotide used in step (a) for detecting said first target polynucleotide sequence of oligonucleotide, a fifth polynucleotide as a probe which is hybridizable with a second target polynucleotide sequence of oligonucleotide and with the labeled first common polynucleotide, the third common polynucleotide attached to the solid phase and used in step (a), and a sixth polynucleotide as a probe which is hybridizable with said second target polynucleotide sequence of oligonucleotide and with the third common polynucleotide attached to the solid phase, to detect the existence of the second target polynucleotide sequence of oligonucleotide. - View Dependent Claims (4, 5, 7, 8, 11, 12, 13)
