Abstract
A method for detecting the presence of cystic fibrosis ciliostatic factor in mammalian body fluid comprises PA0 contacting an enzyme whose activity is inhibited by the factor with a substrate for the enzyme in the presence of the body fluid, the substrate being substantially resistant to reactions catalyzed by enzymes in the body fluid, whereby the substrate is converted by the enzyme at a measurable rate, and PA0 comparing the rate of substrate conversion with the rate of substrate conversion by the enzyme in the absence of cystic fibrosis ciliostatic factor.
