DNA ARRAY AND METHOD OF DETECTING SINGLE NUCLEOTIDE POLYMORPHISM

摘要

A DNA array for detecting a single nucleotide polymorphism (SNP) in a gene having first probe spots, which comprise one or more spots wherein a sequence part hybridizable with a gene polynucleotide is exactly complementary to a first polymorphism mode of the gene, and second probe spots, which comprise one or more spots wherein the sequence part is exactly complementary to a second polymorphism mode of the gene, on a solid support. The probe spots constituting the first probe spots and the second probe spots differ in length from spot to spot. This DNA array makes it possible to more exactly detect an SNP.
