Abstract:
A DNA sample preparation apparatus comprising:a plurality of capillaries as reaction vessels, each immobilizing streptoavidin on an inner surface thereof;a reaction solution vessel containing a reaction solution; andan injector for introducing biotin-tagged DNA samples to the capillaries, wherein a different biotin-tagged DNA sample is introduced into each capillary, and for introducing the reaction solution to said capillaries at substantially the same time, by sucking the reaction solution from the reaction solution vessel, wherein the capillaries are in a bundle at a first end of each capillary so that the injector is attached to the capillaries at the first ends,wherein the different biotin-tagged DNA sample is fixed to the inner surface of each capillary by biotin-avidin bonding; andwherein DNA polymerase reactions are independently carried out inside said capillaries, respectively.
