Abstract
An improved method of electroblotting macromolecules from a chromatographic gel is claimed. The method comprises a design for wire electrode arrays that are capable of generating either highly uniform or controlled predetermined gradient electric fields. A gradient electric field is particularly suited for the quantitative electroblotting of proteins with a wide range of molecular weights.
Claims4
An improved method of electroblotting macromolecules from a chromatographic gel to an immobilizing matrix wherein the improvement comprises:
- (a) measuring the electric field produced by two or more sets of electrodes, each set of electrodes comprising an anode and a cathode which are located in the same saggital plane within the container, whose electric potential can be varied and adjusted independent from other said sets of electrodes and which said sets of electrodes are equispaced from other said sets of electrodes;
- and (b) exposing a chromatographic gel and immobilizing matrix placed in a non-conductive container containing a buffer to the measured electrical field.
