    Abstract:
    We studied the reactivity of monoclonal antibodies (mAbs) raised against acetylcholinesterase (AChE) purified from Electrophorus and Torpedo electric organs. We obtained IgG antibodies (Elec-21, Elec-106, Tor-3E5, Tor-ME8, Tor-1A5), all of them directed against the catalytic subunit of the corresponding species, with no significant cross-reactivity. These antibodies do not inhibit the enzyme and recognize all molecular forms, globular (G) and asymmetric (A). Tor-ME8 reacts specifically with the denatured A and G subunits of Torpedo AChE, in immunoblots. Several hybridomas raised against Electrophorus AChE produced IgM antibodies (Elec-39, Elec-118, Elec-121). These antibodies react with the A forms of Electrophorus electric organs and also with a subset of dimers (G2) from Torpedo electric organ. In addition, they react with a number of non-AChE components, in immunoblots. In contrast, they do not recognize AChE from other Electrophorus tissues or A forms from Torpedo electric organs.
