Motor endplates are composed of a motor neuron terminal and muscle fiber and are distributed in skeletal muscle, causing muscle contraction. However, traditional motor endplate staining methods are limited to the observation of partial skeletal muscle. The procedure was time-consuming due to strict incubation conditions, and usually provided unsatisfactory results. We explored a novel method to label motor endplate rapidly by in vivo injection of fluorescent α-bungarotoxin.
