Improved transfer of high molecular weight proteins using fabric‐reinforced soft polyacrylamide gels

Abstract
Rapid transfer of electrophoretically separated, high molecular weight proteins from fabric‐reinforced, soft, low‐concentration polyacrylamide gels (3.5 %T, 2.6 %C) is described. Polyester fabrics proved useful for gel reinforcement during vertical slab gel electrophoresis. The fabric‐reinforced gel retains its dimension during transfer, equilibration and drying, facilitating comparison of protein bands in the separation gel and transfer matrix.
