Ultrasensitive stain for proteins in polyacrylamide gels shows regional variation in cerebrospinal fluid proteins 

 -  Science, 211(4489), p.1437-1438, 1981 .
<br/><br/> A new silver stain for electrophoretically separated polypeptides can be rapidly and easily used and can detect as little as 0.01 nanogram of protein per square millimeter. When employed with two-dimensional electrophoresis, it should permit qualitative and quantitative characterization of protein distributions in body fluids and tissues. It has been used to demonstrate regional variations in cerebrospinal fluid proteins.
