Abstract

The invention relates to new fabrics with improved properties for the preparation of electrophoresis gels.

Claims

1. A fabric useful for the production of electrophoresis gels comprising a polyester fabric having a mesh size of between about 10 to about 100 μ

m, and also having a multilayer coating consisting of a first layer of a copolymer of maleic acid anhydride and vinylmethylether with diallylamine, a second layer of allylglycidyl agarose and a third layer of a surfactant.

2. A fabric useful for the production of electrophoresis gels comprising a polyester fabric having a mesh size of between about 10 to about 100 μ

m, and also having a two-layer coating consisting of a first layer of a copolymer of maleic acid anhydride and vinylmethylether and a second layer of agarose.

3. A fabric useful for the production of electrophoresis gels comprising a polyester fabric having a mesh size of between about 10 to about 100 μ

m and also having a coating, in at least two layers, of allylglycidyl agorose.

4. The fabric as recited in claim 3 wherein the outer layer of coating also comprises a surfactant.

5. A fabric-supported electrophoresis gel comprising a self-supporting polyester fabric having a mesh size of between about 10 to about 100 μ

m and a thickness of between about 40 to about 70 μ

m, the polyester fabric having a multilayer coating consisting of a first layer of a copolymer of maleic acid anhydride and vinylmethylether with diallylmine, a second layer of allylglycidyl agarose and a third layer of a surfactant, and an electrophoresis gel supported thereon.

9. The fabric-supported electrophoresis gel according to claim 5, the electrophoresis gel being polyacrylamide.

6. A fabric-supported electrophoresis gel comprising a self-supporting polyester fabric having a mesh size of between about 10 to about 100 μ

m and a thickness of between about 40 to about 70 μ

m, the polyester fabric having a two-layer coating consisting of a first layer of a copolymer of maleic acid anhydride and vinylmethylether and a second layer of agarose, and an electrophoresis gel supported thereon.

10. The fabric-supported electrophoresis gel according to claim 6, the electrophoresis gel being agarose.

7. A fabric-supported electrophoresis gel comprising a self-supporting polyester fabric having a mesh size of between about 10 to about 100 μ

m and a thickness of between about 40 to about 70 μ

m, the polyester fabric having a coating, in at least two layers, of allylglycidyl agarose, and an electrophoresis gel supported thereon.

8. The fabric-supported electrophoresis gel as recited in claim 7 wherein the outer layer of coating also comprises a surfactant.
