The project initially centered around using gene therapy using alien DNA to cure terminally-ill cancer patients. These patients quickly recovered, developed super-human strength and the ability to breath underwater. These patients' blood/bloodgas is incredibly toxic to humans and is green in color. The material from the sample was also used in a large scale test on livestock and humans in a small beef farming town in Wisconsin (TXF: \"Red Museum\")."@en .

After a patient, Dr. William Secare, escaped into the population certain sections of the project were quickly shutdown; all evidence and any knowledgeable person(s) were destroyed by Syndicate Operatives. Special Agent Dana Scully gained access to a sample (where \"Purity Control\" was the password) of alien DNA which Deep Throat then used it to negotiate the safe return of Agent Mulder (TXF: \"The Erlenmeyer Flask\").
