Effect of some fibronectin preparations on luminol-dependent chemiluminescence of neutrophils was studied. These fibronectin preparations were obtained after heat denaturation and tryptic digestion. Native fibronectin cause aggregation of gelatin-coated particles and dose-dependent promotion of chemiluminescence of neutrophils, while the rate of these reactions was distinctly decreased if the heat denaturated preparations of fibronectin were used. Structural integrity of fibronectin molecule appears to be responsible for promotion of the neutrophil chemiluminescence.
