In this study, we describe an effective visualizing technique for proteins in SDS‐PAGE based on the organic dye, Eosin B, the sensitivity of which can be further strengthened by the addition of magnesium to the staining solution after electrophoresis. The newly developed protocol is low in cost and easily performed compared with the common methods for protein analysis in 1‐D and 2‐D gels. It provides...
A negative detection method for proteins on SDS‐PAGE is described. In this method, Eosin Y (EY) was selectively precipitated in the gel background, which is absent from those zones where proteins are located through the formation of a stable water‐soluble protein–dye complex. Negative staining of proteins using EY, allows high‐sensitivity, low‐cost, and simple protocol. The new described method takes...
