Ricin ( RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis. The median lethal dose (LD50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection. Oral exposure to ricin is far less toxic. An estimated lethal oral dose in humans is approximately 1 milligram per kilogram of body weight.

Toxalbumins are toxic plant proteins that disable ribosomes and thereby inhibit protein synthesis, producing severe cytotoxic effects in multiple organ systems. They are dimers held together by a disulfide bond and comprise a lectin part which binds to the cell membrane and enables the toxin part to gain access to the cell contents. Toxalbumins are similar in structure to AB toxins found in cholera, tetanus, diphtheria, botulinum and others; and their physiological and toxic properties are similar to those of viperine snake venom.

The museum acts as an educational institution, with its permanent exhibitions bridging together centuries of espionage stories and tactics, immersing visitors in a multi-media experience. The museum particularly focuses on the World Wars and the Cold War through a range of a 1000 different exhibits and artefacts. Since its opening in 2015, 1,000,000 people have visited the museum and recently in 2020 it was nominated for the European Museum of the Year Award. The Berlin Spy Museum is partnered with the International Spy Museum in Washington, D.C., and many of the artefacts and installations within the museum have captured media attention around the world.
