[Gene chip technology and its advances in medical science]

Gene (DNA) chip or DNA microarray is a new technique developed during human genomic research programs. When DNA chip containing thousands of DNA or oligonucleotide are hybridized to labeled samples, gene expression, DNA sequencing as well as DNA mutation and polymorphism can be analyzed with high efficiency in large scale. We are able to perform this technique on dozens of specimens at once in tumor differentiation, tumor typing, tumor diagnosis, tumorigenesis, and new tumor-associated genes discovery.
