    摘要: This invention relates to a horseshoe crab amebocyte lysate factor G activation inhibitor comprising as an active ingredient a polyglycoside containing at least one poly-(1.fwdarw.3)-.beta.-D-glucoside structure portion consisting of 2 to 370 (1.fwdarw.3)-.beta.-D-glucoside structural units of the following formula ##STR1## which are continuously bound to one another. This inhibitor is useful for inhibiting the activation of factor G which may exist in horseshoe crab amebocyte lysate used in the Limulus test.

    摘要: The invention stabilizes single helix conformation (1.fwdarw.3)-.beta.-D-glucans by intramolecular crosslinking and provides (1.fwdarw.3)-.beta.-D-glucans showing stable biological activities. Thus, intramolecularly crosslinked (1.fwdarw.3)-.beta.-D-glucans having a stable single helix conformation are produced by introducing a functional group into hydroxyl groups of (1.fwdarw.3)-.beta.-D-glucans, then causing the thus-obtained functional glucans to take a single helix conformation, and subjecting these, either as such or after binding them to a receptor therefor, to intramolecular crosslinking between the functional groups introduced, if necessary followed by releasing the receptor therefrom.
