Popis: Proteins that migrate through cross-linked polyacrylamide gels (PAGs) under the influence of a constant electric field experience negative factors, such as diffusion and nonspecific trapping in the gel matrix. These negative factors reduce protein concentrations within a defined gel volume with increasing migration distance and, therefore, decrease protein recovery efficiency. Here, we describe the enhancement of protein separation efficiency for up to twofold in conventional one-dimensional PAG electrophoresis (1D PAGE), two-dimensional (2D) PAGE, and native PAGE by implementing pulses of inverted electric field during gel electrophoresis.
