Abstract

An apparatus for transferring biological specimens such as nucleic acid samples from a gel such as an agarose gel to a cooperating transfer membrane by means of a liquid transfer process is disclosed herein along with its method of use. The arrangement includes means for supporting a given gel on top of a given transfer membrane and a trough located below both. An arrangement is provided for defining a reservoir for containing a transfer liquid on top of the gel and means are also provided for causing transfer liquid contained within the reservoir to pass through the gel and transfer medium and into the trough, so as to effect a transfer of particular biological specimens carried by the gel onto the membrane. In the actual apparatus disclosed, the gel and transfer membrane are supported by an assembly of ribs and the trough includes a lowermost segment which is deeper than it is wide in cross-section, which includes graduation marks, and which is configured such that its interior is visible from outside the apparatus, whereby to be able to observe the tranfer liquid as it is being collected within the trough.
