Monoclonal antibodies to and immunoaffinity purification of choline acetyltransferase from bovine brain
Three hybridomas producing monoclonal antibodies to bovine brain choline acetyltransferase (ChAT) have been established by fusion of the spleen cells from a mouse immunized with purified enzyme with myeloma NS-1 cells. All three clones produced IgGl antibodies that reacted with enzyme protein denatured with sodium dodecyl sulfate. By using one of the monoclonal antibodies, a rapid and efficient immunoaffinity purification procedure of bovine ChAT has been established. Immunoblot analysis and immunoaffinity purification indicated that bovine ChAT is a single 68-kilodalton protein. The monoclonal antibodies will offer us a good tool to isolate the cDNA clones encoding ChAT.
