An object of the present invention is to provide a ceramic heater for a semiconductor-producingexamining device which has a short temperature dropping time and can be rapidly cooled. More particularly, the invention relates to methods for fragmentation andor labeling andor immobilization of nucleic acids comprising labeling andor cleavage andor immobilization at abasic sites. The reaction occurs without the need for curing initiators. The data may then be examined to acquire a key set, and a content instance object generated for each datum found which matches a content type. Also provided are methods for utilizing ABC transporter polypeptides to screen for antibacterial compounds. The system permits for the use of multiple users to operate and test glucose levels from a single device.
