Summary of the binding of FITC-conjugated LPS to murine platelets. Murine platelets were incubated with FITC-LPS, and titrations of nonlabeled LPS and FL1 fluorescence were measured by flow cytometry. Results are presented as the percentage inhibition of fluorescence binding and were calculated by the formula (1 – MCF test/MCF control) × 100, where MCF indicates mean channel fluorescence and MCF control indicates no unlabeled LPS added.
