A simple, highly sensitive zymogram technique for detection of endo-1,4-beta-glucanases and endo-1,4-beta-xylanases in polyacrylamide gels after electrophoresis or isoelectric focusing was developed. The detection employs transparent agar replicas containing soluble covalently dyed polysaccharides, hydroxyethylcellulose dyed with Ostazin brilliant red H-3B

New soluble chromogenic substrates were prepared for specific and rapid assays of endo-1,4-beta-xylanases and endo-1,4-beta-glucanases. A soluble beechwood 4-O-methyl-D-glucurono-D-xylan was dyed with Remazol brilliant blue R, and hydroxyethylcellulose was coupled to Ostazin brilliant red H-3B. The assays are based on
