A method for determining the number of tandem repeats in a target polynucleotide, the method comprising (a) providing a sample containing the target polynucleotide, wherein one or more of the tandem repeats in the target polynucleotide is in single stranded form, (b) hybridising a labelled probe oligonucleotide to the single stranded portion of the target polynucleotide, wherein the probe oligonucleotide is complementary to at least one of the tandem repeats, and at least 5 nucleotides of the probe oligonucleotide are complementary to the tandem repeats, in the single stranded portion of the target polynucleotide, and (c) determining the number of tandem repeats in the target polynucleotide based on the hybridisation of the probe oligonucleotide to the single stranded portion of the target polynucleotide. |
