Cilia isolated from tetrahymena after membrane stabilization by 1,5-difluoro-2,4-dinitrobenzene

The tendency for Tetrahymena pyriformis cells to lyse when they are centrifuged at speeds above 120g and then exposed to an ethanolic deciliating medium is inhibited by treatment with 1,5-difluoro-2,4-dinitrobenzene. This treatment facilitates greater yields and purer preparations of isolated cilia. Cilia from treated and untreated cells do not differ in some of their biochemical properties.
