To examine the existence of negative cooperativity among formyl peptide chemotaxis receptors, steady-state binding off Met-Le~-[~H]Phe to viable rat neutrophils and their purified plasma membranes was measured and the data were subjected to statistical analysis and to computer curve fitting using th
## Abstract We extracted a pure protein from __Tetrahymena pyriformis__ as the chemotactic substance in __Amoeba proteus__. The protein was heatβstable, negatively charged at neutral pH (since its isoelectric point was near pH 4.5) and composed of three subunits. Its molecular weight was 3 Γ 8,000.
