Alcian blue staining of proteoglycans in polyacrylamide gels using the "critical electrolyte concentration" approach

Anal Biochem. 1988 Nov 15;175(1):298-9. doi: 10.1016/0003-2697(88)90392-2.

Abstract

A method is described here for Alcian blue staining of proteoglycans in polyacrylamide gels; this is illustrated using extracts obtained from bovine corneal stroma. Other available methods for visualization of proteoglycans can produce nonspecific staining and frequently a high background in the gel; with a "critical electrolyte concentration" approach, specific staining against a clear background can be obtained.
