Modular probes for enriching and detecting complex nucleic acid sequences

Modular hybridization probes (M-Probes) have been developed that enable sequence-selective binding of complex nucleic acid targets. The M-probes can target sequences that: are hypervariable at prescribed loci, are long continuous sequences of over 500 nucleotides, or contain repetitive sequences. A hybrid-capture assay using the M-probes was developed that was capable of determining the exact triplet repeat expansion number in the Huntington's gene from genomic DNA.
