PROBLEM TO BE SOLVED: To remove endotoxin from a low endotoxin-containing pharmaceutical solution, to have high selectivity in any ionic strength range and to remove endotoxin extremely efficiently, and polylysine of the polylysine. Provided are a production method, a polylysine composition for removing endotoxin, and a method for producing a drug for removing endotoxin using the polylysine. A polylysine having a crosslinked structure with a crosslinking agent. |
