Binds to the main immunogenic region on the extracellular surface of the α1 subunit of muscle AChR′s and to homologous regions on α3 and α5 subunits of neuronal AChR′s. The epitope is located on the extracellular surface of the α1 subunit of the muscle nicotinic acetylcholine receptor. The antibody binds to denatured chick α5 AChR, but does not bind well to denatured α3, α4, α7, α8, and β2. It may also bind β3 due to homology of main immunogenic region. May be used to localize and detect the α1, α3 and α5 subunits of the nicotinic acetylcholine receptor (AChR).


nicotinic acetylcholine receptor from the electric eel Electrophorus.

Physical form

Solution in 20 mM Na3PO4, pH 7.2, containing 150 mM NaCl and 0.05 % sodium azide.
