Analysis of β-(1,3)-glucans of M. restricta by gel filtration chromatography on a Sephacryl S300 column. β-(1,3)-Glucans were isolated after periodate oxidization, reduction, and Smith hydrolysis of WSDN fraction and desalted by dialysis (cut off of 1 kDa). Neutral sugars were detected by phenolsulfuric acid assay (16). β-(1,3)-Glucans were detected by Lam-A digestion and p-hydroxybenzoic acid hydrazide reagent (25). The Sephacryl S300 column was calibrated with dextrans (T500, T70, T40, and T10), and glucose.
