ACCELL Gene Gun Protoype

Description (Brief)
The first gene gun was the brainchild of John Sanford, a plant geneticist working at Cornell in the early 1980s. The invention was a crude but ingenious concept: use the principles of a normal gun to blast DNA-covered microbullets at plant cells, thereby introducing foreign DNA and creating transgenic plants. As word of Sanford’s research spread, genetic engineers at Agracetus, the Middleton, Wisconsin-based biotech firm found their own inspiration.
Spurred by word of Sanford’s gun, Agracetus employees Dennis McCabe and Brian Martinell invented a gene gun of their own in 1986. Cobbled together from scrapped radar station parts McCabe had purchased years earlier from the University of Iowa and potato chip bags from the Agracetus vending machine, the prototype, seen here, utilized a high-voltage electric shock to transform a water droplet into a shock wave that drove DNA-coated microparticles of gold into plant tissue. By April 1988, McCabe and Martinell had used the gun to create the first genetically transformed soybeans. Their success led to a deal with Monsanto to develop RoundUp Ready soybeans.
Over the course of the 1990s, Agracetus developed the prototype gene gun into a marketable product, christening it ACCELL technology for “ACcessing any CELL.” The guns were licensed to Grace and DuPont in April 1992, and by November 1994 Agracetus reached an agreement with Bio-Rad to manufacture and market the guns.
