title: Effect of 1,3;1,6-beta-D-glucans on developing sea urchin embryos.
abstract: The effect of 1,3;1,6-beta-D-glucooligo- and polysaccharides with different structures (from 1 to 10 kDa of molecular mass; from 10-25% of beta-1,6-linked glucose residues content) on the developing embryos of sea urchin, Strongylocentrotus intermedius, was evaluated for the screening of potential positive stimulants. 1,3;1,6-beta-D-glucans with a molecular mass of between 6-10 kDa and at concentrations of 0.05-0.25 mg/ml shown the best modulator effect on the sea urchin embryos. 1,3;1,6-beta-D-glucans increased the survival of the sea urchin embryos up to 2.5-fold compared with the control animals.
