Arg concentrations	Arg	ArgΔ(I/L)WEQ	ArgΔCH	Abl
μm
0 (control)	−3.3 ± 0.16a
0.3	−3.2 ± 0.17	−2.7 ± 0.11	−3.8 ± 0.26	−2.7 ± 0.17
1	−0.45 ± 0.09	−2.3 ± 0.13	−0.37 ± 0.08	−0.43 ± 0.07
0.3 + 0.15 μm cortactin	−0.6 ± 0.13	−0.84 ± 0.13	−0.62 ± 0.13	−2.6 ± 0.19

^a Polymerization rates are in subunits/s. Errors are standard error from the analysis of 10–20 filaments.
