glucanase assays

[Lisa Vaillancourt]

Hello!  I am wondering if anyone knows of a simple assay (preferably a
colorimetric one) that I could use, preferably on intact tissue of
Schizophyllum commune, to quantify the levels and activity of
beta-glucanase enzymes?   Thanks in advance for any help on this.
