The invention provides an oligonucleotide comprising a nucleotide sequence consisting of SEQ ID NO: 1. The invention also provides method for detecting target DNA in a sample with the oligonucleotide.

Oligonucleotide and method for detecting target DNA in a sample by fluorescence from copper nanoparticles

A method for diagnosing spinal muscular atrophy is provided. The method includes providing a biological sample of a subject containing a nucleotide of SMN gene, amplifying SMN exons, andby a universal multiplex PCR using the nucleotide as a template and the primers to obtain fragments of the SMN exons, and, labeling the fragments of the SMN exons, andby a fluorescent primer to obtain fluorescence-labeled exon fragments, and analyzing the fluorescence-labeled exon fragments by a capillary electrophoresis. If the SMN1/SMN2 ratios in exonandare different, it indicates that the subject is susceptible to spinal muscular atrophy. Additionally, if the peak of certain exon fragment appears crossed, it indicates an intragenic mutation in the exon.

Method for diagnosing spinal muscular atrophy

A method for diagnosing spinal muscular atrophy is provided. The method includes providing a biological sample of a subject containing a nucleotide of SMN gene, amplifying SMN exons 1, 2a, 2b, 3, 4, 5, 6, 7, and 8 by a universal multiplex PCR using the nucleotide as a template and the primers to obtain fragments of the SMN exons 1, 2a, 2b, 3, 4, 5, 6, 7, and 8, labeling the fragments of the SMN exons 1, 2a, 2b, 3, 4, 5, 6, 7, and 8 by a fluorescent primer to obtain fluorescence-labeled exon fragments, and analyzing the fluorescence-labeled exon fragments by a capillary electrophoresis. If the SMN1/SMN2 ratios in exon 7 and 8 are different, it indicates that the subject is susceptible to spinal muscular atrophy. Additionally, if the peak of certain exon fragment appears crossed, it indicates an intragenic mutation in the exon.
