The fraction of moving filaments in vitro motility assay with ATP and dATP at increasing ionic strengths. The fraction of moving filaments at ionic strengths 100 to 150 mM are shown for conditions with ATP and with dATP. There were between 20 and 1600 filaments measured for each group (number of filaments decreased with increasing ionic strength) on 4–15 slides. Bars represent mean + SD of the fraction of moving filaments. *P < 0.05.
