Abstract: The present invention relates to a modified PNA oligomer for detecting gene methylation. By using a PNA probe modified by introducing a methyl group-specific substituent to the gamma position, N-terminus or C-terminus of the PNA, the present invention may be used for a method for detecting using a difference in physical properties between a gene and a non-methylated gene caused by an interaction between the probe and methyl groups of the gene.

Abstract: The present invention relates to a method of detecting multiple targets based on a single detection probe, and more particularly to a method of detecting multiple targets by amplifying each target with primers including an SNP-containing tag sequence, hybridizing the amplification products with a single detection probe capable of binding to the tag sequences and designed such that melting temperatures are different from each other, and analyzing melting curves. A method of detecting multiple targets according to the present invention enables the detection of multiple targets using a single probe, and thus is useful for detecting multiple targets because false positives are reduced and multiple targets are detectable with high sensitivity and at a rapid rate.

Abstract: The present invention relates to a method for analyzing the presence or absence of aneuploidy of a target chromosome with high sensitivity, and a composition for detecting chromosomal aneuploidy, and more particularly to a method of identifying chromosomal aneuploidy by amplifying a control nucleotide sequence, located on a chromosome not associated with chromosomal aneuploidy, and a target nucleotide sequence located on a chromosome associated with chromosomal aneuploidy, by using the same primer, and then hybridizing the amplification products with an assay probe that differs by one or two nucleotides from the control nucleotide sequence and with an elimination probe that comprises part or all of a sequence of the assay probe, which hybridizes with the target nucleotide sequence or the control nucleotide sequence, the elimination probe having a higher binding affinity for the amplification products than the assay probe, and analyzing melting curves of the hybridization products.
