Abstract
An apparatus for the separation and fractionation of differentially expressed gene fragments includes a separating means including a capillary filled with a separation medium to separate DNA fragments by electrophoresis, a sampling means including sampling vessels to fractionate and sample the separated DNA fragments, according to their size, a transferring means to transfer buffer solution containing the separated DNA fragments to the sampling means, and a control means to control the sampling means based on a signal gained by detecting means, wherein a voltage for the electrophoresis and a length of the capillary are adjusted such that a spread in time of the separated DNA fragments caused by the transferring means during the transfer of the separated DNA fragments to the sampling vessels is smaller than a difference in separation time of the DNA fragments in the separating means.
