    • A bed of water insoluble, transparent, cross-linked gel, suitable for use in electrophoresis, is formed by dissolving a polysaccharide, including at least one linear polysaccharide such as agarose or hydroxyethyl cellulose, in a suitable solvent, such as water; adding a cross-linking agent, which is not charged nor becomes charged upon contact with water in a pH range of 2 to 11, to the solution; and incubating this mixture in a quiescent state to substantially simultaneously react the polysaccharide and the cross-linking agent and to gel the reaction product into a bed. The polysaccharide is at least one linear polysaccharides, but that linear polysaccharide may also be admixed with other linear polysaccharides and/or at least one non-linear polysaccharide. Synthetic organic polymers may also be admixed in the cross-linking reaction mixture. The polysaccharide, and/or other polymers in the cross-linking reaction mixture may be charged but are preferably uncharged, but if charged, the charge must be low enough so that the charge of the resulting gel, if any, will not interfere with the use of the gel to support an electrophoresis process. When the linear polysaccharide is agarose, the gel has improved elasticity, transparency, and, when the gelled cross-linked product is used to support electrophoresis, improved resolution of small DNA molecules as compared to the results achieved by using an agarose polymer which has not been cross-linked according to this invention.

    • A novel synthesis of N-acryloyl-tris-(hydroxymethyl)aminomethane (NAT) is described. The polymerization kinetics and transparency of the poly(NAT) gels crosslinked by a crosslinker (CL) e.g. N,N'-methylenebisacrylamide (Bis), i.e. poly(NAT+Bis) polymer, are shown. Poly(NAT+Bis) gradient (4-24%) gels were prepared and found to resolve native proteins according to their size. The exclusion limit of these gels is over 3.times.10.sup.6 Da. This is more than threefold higher than the exclusion limit of the polyacrylamide gradient gel of the same concentration. Therefore poly(NAT+CL) gels are better than polyacrylamide gels for the resolution of large proteins. It was demonstrated that poly(NAT+CL)-polyacrylamide composite gels could be prepared. The poly(NAT+CL) gels were found to be advantageous also for isoelectric focussing in carrier ampholytes or immobilized pH gradients. Poly(NAT+CL) gels are also very good for separation of nucleic acids. The resolution is particularly good in the range between several hundred to 4-5000 base pairs. Under the optimized conditions, DNA molecules of more than 20 kbases can be perfectly resolved.

    • The method of electrophoresis uses for separation of charged species their different mobilities in an electric field. The process is usually carried out by forcing the molecules to migrate through an aqueous gel. The gels are run in essentially two types of electrophoretic units: vertical and horizontal ones. It was found that in the standard submerged electrophoresis units the resolution of DNA in the poly(NAT) gels was never so good as in the vertical system. It was observed that by looking at the gel from above under an angle declined from the vertical, the viewed DNA bands in the gel were much sharper than they were pictured on the photograph taken by a camera positioned more or less vertically above the gel. On basis of this observation it was assumed that the diffuseness of bands seen on the photograph did not originate from a real diffuseness of bands in the gel, but rather from the vertical position of the camera and bending of the bands against the vertical axis. If the bands in the gel could be made essentially vertical, then the resolution taken by the usually positioned camera would be qualitatively better and besides that independent of the sample volume. It is the main goal to prevent such bending of bands in gels during electrophoresis.

    • A preparative electrophoresis apparatus suitable for recovery of molecules from gels comprises two spaced apart electrode compartments connected by a conduit that descends from the bottom of the electrode compartments in a V-shaped or U-shaped form. The conduit serves as a reservoir for collecting electroeluted molecules. Two electrophoresis buffers are used, a first one of a low concentration and density, and a second one of a high concentration and density. The electrode compartments are filled with the first electrophoresis buffer solution while the conduit is filled with the second electrophoresis buffer solution. Under the influence of an electric field, the molecules exit the gel and concentrate in the high concentration buffer. After a certain time, usually a time that is sufficient for driving substantially all desired molecules out of the gel, the electric field is switched off. The high concentration buffer containing the electroeluted molecules is withdrawn from the conduit. The target molecules may be recovered from the high concentration buffer solution.
