Effects of WKYMVm on fML[3H]F binding to neutrophils.
The radiolabeled formylpeptide fML[3H]F (final concentration, 2 × 10−8 mol/L) was allowed to bind in the absence or presence of increasing concentrations of nonlabeled WKYMVm or fMLF and the amount of cell-associated radioactivity was determined after removal of nonbound peptide. The results are expressed as percent inhibition induced by the peptides. The amount of peptide bound in the absence of nonlabeled peptide was 28 ± 6 fmol/106 cells. The figures represent the mean values (± SD) of 4 experiments.
