Effects of preincubation of anti-trkB₂₃ and anti-trkB₁₄₆ with cognate or heterologous peptide on the pattern of immunohistochemical staining. Adjacent E30 horizontal sections were stained with anti-trkB₂₃ (1 μg/ml) after preincubation with either buffer (A), peptide 23–36 (B), or peptide 146–163 (C). Adjacent P10 sagittal sections were stained with anti-trkB₁₄₆ (1 μg/ml) after preincubation with either buffer (D), peptide 23–36 (E), or peptide 146–163 (F). Abbreviations as in Figure 5. Scale bars: A–C, 50 μm;D–F, 65 μm.
