Hydrolysis-based probe and method for STR genotyping Universiteit Gent
The present invention relates to the field of genotyping samples containing short tandem repeat (STR) loci. More specifically, the present invention discloses a composition of matter containing an array of probes and a method to genotype these loci relying on the recognition of RNA:DNA base pairing followed by cleavage of the RNA containing strand. By measuring the temperature at which the chimeric DNA-RNA-DNA probe is cleaved, resulting in an increase of fluorescence of the probe, it can be assessed whether or not the probe and the sample share the same amount of repeats. An array of probes ...
