Polymer complexes formed by schizophyllan and poly(C) showed a unique antihydrolysis effect when poly(C) was subjected to hydrolysis under basic conditions. The complexation reduced the hydrolysis rate to 80% of the control (i.e., poly(C) itself). However, when we added oligoamines with the intentio

Schizophyllan belongs to a beta-1,3-D-glucan family, which exists as a random coil in dimethyl sulfoxide (DMSO) and as a triple helix in water, respectively. The schizophyllan single chain forms a complex with single-stranded homo RNAs in water/DMSO mixed solvents. Using circular dichroism, we studi
