[Detection by the use of silver ions of additional protein zones in gradient polyacrylamide gels stained with Coomassie].


A simple method of revealing the additional zones of proteins in gradient polyacrylamide gels, preliminary dyed Coomassie by means of silver ions is described. The dyeing of Coomassie allows to avoid the time-consuming stages of preliminary treatment of gels as well to reveal more sensitive zones in gels. On the second stage of dyeing silver minor zones… (More)
