Inhibition of the turning response toward NGF-coated beads by the application of trkA and p75 receptor antibodies. In the presence of the trkA antibodies (CTA, 25 μg/ml), growth cones did not turn toward NGF-coated beads more than toward cyto-C beads. Both 14 (C1) and 70 (C2) μg/ml antibodies against p75 (Chex) diminished, but did not abolish, the turning response of growth cones toward NGF-coated beads. Antibodies against trkB (20 μg/ml) or L1 (25 μg/ml) did not affect the percentage of growth cones that turned toward NGF-coated beads. The percentage of growth cones that turned toward NGF-coated beads in the absence of antibodies (no Ab) is provided for comparison purposes. All experiments were performed with a 0.05 ng/ml background NGF concentration.
