| Research Abstract |
Clinical application of the genetic information to individual healthcare requires simple and rapid identification of nucleotide changes in clinical settings. We have devised a novel low tech method for the detection of a single nucleotide substitution using competitive allele-specific short oligonucleotide hybridization with immunochromatographic strip. The gene of interest is PCR amplified, hybridized to an allele-specific short oligonucleotide probe in the presence of a competitive oligonucleotide, and subjected to chromatography using a DNA test strip at room temperature. The genotype is unambiguously determined by the presence or the absence of visible purple lines on a strip. Feasibility of the method was demonstrated by the detection of a prevalent disease-causing mutations in a number of single-gene diseases and clinically important pramacogenetic polymorphisms. The procedure does not demand either technical expertise or expensive instruments and is readily performed in local clinical laboratories. The result is obtained within 10 minutes after PCR. The rapid and simple method may be used for point-of-care genetic diagnosis with potentially diverse clinical applications.
