Applied Biosystems has launched its Human Genome Survey Microarray V2.0, an updated version of its human genome array. The new chip contains roughly 33,000 probes and over 8,000 genes not covered by other commercial arrays, ABI said. The array runs on the firm’s Expression Array System.
DNA Chip Research and Sumitomo Bakelite have developed a technique called Multiple Primer Extension of a Chip (MPEC), which makes an assay that they claim is 100 times more sensitive than conventional assays.
Nisshinbo Industries and Japan Tobacco have created a new method to identify varietals in rice. Using Nisshinbo’s DNA microarray technology, the method can identify within six hours 20 separate rice brands that are sold in Japan. Genetic ID, a Yokohama-based gene testing service that has been contracted by many Japanese firms to prevent mislabeling of their food and feed products, will start using the technology this spring. Nisshinbo said it cost the company ¥15 million ($150,000 US) to develop and that the technology will not be licensed to other firms.
