Monoclonal antibodies against the high affinity choline transport system.
Monoclonal antibodies have been isolated that specifically block the high affinity, Na(+)-dependent transport of choline in insect synaptosomes and synaptosomal ghosts. Antibodies were derived after immunization of mice with synaptosomal membranes from locust. Antibody VIB6F5, an IgG isotype, significantly inhibited the high affinity translocation of choline, the effect exhibited saturation at increased antibody concentrations. Antibodies recognized a 80 kDa antigen identified by Western blot analysis of synaptosomal membranes. In immunocytochemical approaches VIB6F5 specifically stained distinct areas in the neuropil of head and thoracic ganglia.
