A proportional analysis method using non-kinetic real-time PCR.
Prompted by increasing interest in proportional analysis of genetic types, we developed a simple assay technique for determining the ratio of a specific target gene in the total genes that can be amplified with the same PCR primer. The key feature of this method is that the following two tasks are performed in a single-tube real-time PCR system: task 1, PCR amplification of the total genes including the target using a labeled PCR primer, with concurrent monitoring of the total copy number of the PCR product; task 2, detection of the signal of the target gene at each cycle of amplification, using a labeled nucleotide probe. In principle, the ratio of the target gene to the total genes is represented by the signal detected in 'task 2' at the cycle in which the PCR product reached a prescribed copy number (assessed by 'task 1').
