Abstract:
A method by using ?-BT-HRP conjugate to localize N-acetylcholinc receptor of neuromuscular junction was described.Thin strips of fresh muscle were incubated with ?-BT-HRP conjugate at a concentration of 1?10-7 M in Tyroid's solution and then reacted with Karnovsky's DAB medium.There were obviously brownish red positive deposits to constitute various vesicular forms seen under a light microscope. Under an electron microscope we can see positive deposits that were localized both on the presynaptic and postsynaptic membra-nes. The binding activity and reliability of a-BT-HRP were discussed.
