Crude beta glucan binding protein (BGBP) profiling of oyster, Crassostrea iredalei and its functional assays

Abstract

Crude (B-1, 3-glucan binding protein was successfully isolated from slipper oyster, Crassostrea iredalei using laminarin (B-glucan) precipitation. Plasma concentration of C. iredalei was 0.121 mg ml-1 protein and contains a weak hemagglutinating activity. Supernatant could agglutinate most of red blood cells (RBC) tested due to presence of laminarin in contrast to whole plasma and pellet.
