title: [Detection of DNA-binding proteins in polyacrylamide gel after denaturing electrophoresis].
abstract: A simple method for detection of DNA-binding proteins is offered. These proteins can be revealed, following their electrophoretic separation in sodium dodecyl sulfate (SDS)-polyacrylamide gel containing labeled DNA, by washing the gel in buffer to remove SDS and to allow protein renaturation. Protein-free DNA is washed out, remaining in the DNA-binding proteins that restored their original characteristic. After autoradiography these proteins are seen as black bands (by one-dimensional gel electrophoresis) or spots (by two-dimensional gel electrophoresis) on a grey background. High sensitivity of the method is shown by using protein fractions of rat liver and a standard method.
