<p>Electrophoretic separation apparatus (10) comprises a gel matrix medium (28) for supporting macromolecular particles to be separated, the medium (28) having opposed faces separated by a thickness of medium small in relation to the dimension of the faces and including one or more separation tracks (30); first electrode means (40,46) positioned about said medium for applying, upon energization, a first electric field (48) across the or each separation track, the direction of the first field intersecting both planar faces and oriented at an angle which is acute with respect to a first planar face; second electrode means (42,44) positioned about said medium for applying, upon energization, a second electric field (50) across the or each separation track, the direction of the second field intersecting both planar faces and oriented at an angle which is acute with respect to a second planar face; and means for alternately and repetitively energizing the first and second electrode means (62). </p> |
