Neogen Corporation
A maker of diagnostic test kits and lab supplies, Neogen helps food producers catch pathogens, toxins, and allergens in their products, and supplies veterinary medicines, vaccines, and genomics testing for livestock and pets. Founded in 1982 in Lansing, Michigan, it grew out of scientific breakthroughs from Michigan State University that were, as the founders put it, "solutions searching for problems." Its name blends the Greek "neo" for new with "gen" for generation — a fitting nod to a company born from a university's newest ideas.
