Ricin: Culture & Applications

Ricin (/ˈraɪsɪn/ RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor plant, Ricinus communis. The median lethal dose (LD50) of ricin for mice is around 22 micrograms per kilogram of body mass via intraperitoneal injection. Oral exposure to ricin is far less toxic. An estimated lethal oral…
