| 摘要 |
The present invention relates to a real-time Polymerase Chain Reaction (PCR) method for the detection and quantification of variants of nucleic acid sequences, which differ in the probe-binding site. The method is based on the complete and/or partial amplification of the same region of the variants and the addition of two or more oligonucleotide probes to the same PCR mixture, each probe being specific for the prob-binding site of at least one variant. The method can be applied e.g. to estimate the viral load in a sample, to differentiate between subgroups, subtypes isolates or clades of a viral species or to estimate the impact of the viral load on tumorgenesis. |
