Immunitech Research is a subsidiary company within Zeditron Industries. Immunitech successfully cloned dozens, if not hundreds, of symbiotes from the original Goa'uld which took over the body of Adrian Conrad. The symbiotes were implanted into the population of Steveston, Oregon. The NID began surveillance on them in the hope that they would eventually be able to gain useful technological information from the symbiotes. Immunitech designed the symbiotes with a built-in "kill" switch in the event something disastrous occurred, such as the Goa'uld realizing that they were under surveillance. (SG1: "Nightwalkers")
