[Identification of cysteine-containing proteins following separation by disk electrophoresis]

Several approaches to measurements of cysteine-containing proteins are known. These proteins are essential for normal function of cells, tissues, organs, and the total organism under natural conditions and during exposure to exo- and endogenic pathological factors. Unfortunately, the routine methods are inconvenient and have many drawbacks, which impedes their wide use. The authors suggest a simple, cheap, and rapid method for identification of cysteine-containing proteins after their separation by disk electrophoresis in polyacrylamide gel.
