Blue Dry Western: simple, economic, informative, and fast way of immunodetection.

The analysis by electrophoresis followed by transfer to membranes and immunodetection (Western blot) is probably the most popular technique in protein study. Accordingly, it is a time- and money-consuming procedure. Here a protocol is described where immunodetection can be accomplished in 30 min. This approach also allows permanent staining of proteins by Coomassie Blue R on the membrane before immune staining with clear background and high sensitivity.
