| 摘要 |
<p>This invention provides an apparatus for extracting nucleic acids from nucleic acid-containing samples, particularly biological samples, more particularly to a nucleic acid extraction apparatus suited for utilizing a nucleic acid-binding magnetic carrier. The nucleic acid extraction apparatus of the invention comprises (1) a group of extraction vessels each comprising a reactor tube with a sample, a reagent solution, a magnetic carrier respectively, a drain cup, and a nucleic acid recovery tube, (2) a distribution means for introducing a solution into each extraction vessel, (3) a stirring means for mixing the solution and magnetic carrier, (4) a holding means for holding the magnetic carrier stationary within the vessel, (5) a discharging means for discharging the solution from the reactor tube while the magnetic carrier is held stationary, (6) a heating means for heating the contents of the reactor tube, and (7) a transfer means for serially transferring the vessels to predetermined positions. <IMAGE></p> |
