Production of a monoclonal antibody directed against the nerve growth factor receptor from sympathetic membranes

Spleen cells from BALB/c mice immunized with a plasma membrane‐enriched fraction from rabbit sympathetic ganglia were fused with the mouse myeloma NS1. A hybrid clone was obtained that produced monoclonal antibody directed against the receptor for nerve growth factor (NGF). The antibody, identified as IgG, was able to immunoprecipitate solubilized NGF receptor in the presence or absence of bound NGF. The antibody bound specifically to sympathetic membranes with high affinity but did not affect the binding of 125I‐NGF to its receptor in sympathetic or sensory neurons or PC12 cells.
