MICROARRAY-BASED SINGLE NUCLEOTIDE POLYMORPHISM, SEQUENCING, AND GENE EXPRESSION ASSAY METHOD

摘要

There is disclosed a microarray-based single nucleotide polymorphism, sequencing, and gene expression assay method. Specifically, there is disclosed a method using a microarray device wherein a plurality of hybridized structures is formed by contacting the microarray under a hybridizing condition to a hybridizing solution comprising a plurality of tagged targets and a plurality of detection sequences. The detection sequences of each hybridized structure is extended using an extension-ligation solution and an extension-ligation condition. After extension, ligation of the extended sequence occurs to a probe if the terminal nucleotide of a probe is complementary to the hybridized tagged targets. Non-bound material is removed by using a washing solution and a washing method. The target nucleotide and the target sequence of the tagged targets is determined by which probe is ligated to the detection sequences.
