Area and F-actin content were quantified using NIH Image on images as described in Materials and Methods. Both control nonimmune rabbit IgG and Ab286 anticofilin were microinjected at a concentration of 6 mg/ml. 1–2 h after microinjection, the cells were stimulated for 1 min with EGF and fixed and stained for F-actin.
