Summary
This product is for research use only. Do not administer it to human.
Curdlan is produced as a water-insoluble polysaccharide by the soil bacterium, Alcaligenes faecalis var. myxogenes, and was discovered by Dr. T. Harada at the Institute of Scientific and Industrial Research, Osaka University. One of the characteristics of Curdlan is that when the suspension is heated, it becomes a thermally irreversible gel. Curdlan is used as gel filtration support, affinity chromatography support, immobilized enzyme support, starch jelly and low calorie food or a material hardening substance. Curdlan has gained attention as a research material for gelation mechanism or as a basic material for anti-tumor olysaccharide research.
