| Research Abstract |
Including exon-microarray, current microarray technology can detect only relative changes of mRNA expression. We tried to develop a new method to measure amount of each exon expression as copy number per one cell, for enhancing the performance study of splicing-variant in various situations. In the course of the study, we have revealed that serious errors are caused on exon microarray by "semi-specific hybridization", a kind of cross-hybridization among nucleotides sharing partially common sequence. As a result, we generated a new basic theory which can improve quality of exon-microarray data based on the sequence data of probes and targets taking the semi-specific hybridization into account.
