<p>Gradient gels are formed in a slab gel enclosure by introducing gel solution through a channel in one of the two or more spacers which set the thickness of the gel. The channel opens into the gel space through an aperture in the inner longitudinal edge of the spacer at approximately mid-length along the edge, and filling of the gel space with the solution is performed with the enclosure rotated onto its side. In certain embodiments of the invention, the opposing spacer contains an aperture as well, plus a channel leading from the aperture to the exterior of the enclosure, for venting of air from the gel space as the space is being filled with the gel-forming liquid.</p> |
