Gene Gun
A gene gun is a device used to introduce genetic material to cells through the use of tiny DNA-coated particles fired at high velocity into a cluster of cells. Gene guns are used in laboratory settings to conduct research, develop new products, and tag samples of materials.The gene gun was created as a new way of proceeding with gene transformation of grains in response to the difficulty of getting bacteria across grain cell walls. It was designed by John Sanford at Cornell University in 1987 and made introducing new genetic material into plant cells much easier than previous methods, such as the use of viruses or agrobacterium.
