HEK 293 cells may vary. The following proteins of interest (among many others) are commonly found in untreated HEK 293 cells: HEK 293 cells Human embryonic kidney 293 cells, also often referred to as HEK 293, HEK-293, 293 cells, or less precisely as HEK cells, are a specific cell line originally derived from human embryonic kidney cells grown in tissue culture. HEK 293 cells have been widely used in cell biology research for many years, because of their reliable growth and propensity for transfection. They are also used by the biotechnology industry to produce therapeutic proteins and viruses for gene therapy. HEK 293
Nevada State Route 487 designation until 1942, other state maps show the route number existing on the highway by 1937. The route was upgraded to a gravel road by 1948, and was fully paved by 1949. SR 73 was eliminated from the state highway system as part of a mass renumbering of Nevada's state routes.
