Concentration-dependent inhibition of [ ¹²⁵ I]-G-CSF binding by BK0023 (black circle) and Neupogen ^® (open circle) in NFS-60 cells expressing G-CSF receptor. Data are reported as percent of specific binding at each concentration of displacer and are the means ± S.E.M. of four separate experiments. Statistical analysis by Student’s t-test did not show any significant difference between BK0023 and Neupogen^®.
