Monoclonal antibodies to leucine enkephalin.
Monoclonal antibodies to leucine enkephalin have been produced after fusion of mouse myeloma cells with spleen cells from hyper-immune mice. Hybrid clones 2D1 and SL1 were characterised using radioimmunoassay and an enzyme-linked immunosorbent assay. The antibody 2D1 was of low affinity and showed a maximum sensitivity of 0.1ng. The antibody binds equally well to the sulphated leucine enkephalin and to methionine enkephalin. It does not cross-react with dynorphin, methionine enkephalin-arg-phe or oxidised methionine enkephalin. The hybrid clone SL1 appears to be specific for leucine enkephalin. Preliminary immunocytochemical studies have shown that both antibodies bind specifically to leucine enkephalin in defined areas of the central nervous system.
