Dividing and fractionating device

摘要: PURPOSE: To prevent a specimen from loosing due to the adsorption and lowering efficiency of division by locating dividing cell array in way an electrophoretic migration passage or right after passage. CONSTITUTION: A DNA piece is injected upper portion 11 capillary gel. fluorescent indication applied voltage electrodes 9, 10 cause thereof. The divide accordance with size appearance can be monitored means detector 14. passes through small hole 13 enter cells 3. stops at region for long time. When passing detected monitoring, cartridge 2 moved motor 15 detecting section delaying time wherein considered. Each 3 are supported between lower support plates 4, 5 so that held therein. has 12 opened on respective plate holes corresponding form bottom each sized as neglect leakage therethrough.
