"Agar is used as an emulsifying agent, as a tablet disintegrant, and as a culture medium in bacteriology. It is also used as a thickener in the food industry. Pure agarose and agarose derivatives are used for chromatographic, electrophoretic, and affinity-chromatographic separations in biochemistry."
