Abstract
A means for selectively removing ET under coexistence of a substance showing a negative charge, such as nucleic acid is described. Endotoxin is selectively removed by bringing a polymer obtained by crosslinking cyclodextrin with an isocyanate-based crosslinking agent in contact with a solution containing endotoxin and the substance showing the negative charge such as nucleic acid.
