METHOD AND APPARATUS FOR USE IN BIOLOGICAL TESTING |
摘要 |
A method and apparatus for use in biological testing. The apparatus comprises electrophoresis apparatus comprising a tank (1) the interior of which is formed with a raised portion (5) which splits the tank into two compartments (6,7) containing electrophoresis electrolyte. Electrodes (8) are provided in each compartment, Electrophoresis is carried out through a gel (not shown) supported by a rigid porous plate (11). The gel is cast onto the porous plate with a transfer membrane (not shown) between the porous plate and the gel. Further electrodes (20,21) are mounted below and above the gel respectively. The method of the invention comprises a first stage using the electric field produced by the electrodes (8) to draw the samples through the gel and a second stage using the electric field produced by the electrodes (20,21) to draw the distributed macromolecules onto the transfer membrane.
