Protocol describes a competitive ligand binding assay for cortical neurotrophin receptors. Following binding in the presence of competitor, the bound radiolabeled ligand is cross-linked to the receptor. The cells are lysed and the ligand-receptor complexes are immunoprecipitated using a pan-trk (tyrosine kinase receptor) antibody. Protocol includes:Preparation of Cortical Tissue for Competitive Crosslinking, Competitive Binding, Crosslinking Ligand to Receptor, Lysis and Immunoprecipitation etc
