Point mutation of specific genome DNA causes cancer. A system for rapid and sensitive detection of specific genome DNA is required because it enables early detection and treatment of cancer. We developed a new system for DNA diagnosis using DNA-carrying latex particles and succeeded to collect point mutant specifically from the mixture with normal DNA of codon 12 of K-ras gene.
