Glutamate Receptors at the Embryonic Zebrafish Neuromuscular Junction

Glutamate receptors are known to have a wide range of diversity in the CNS, but are largely absent in the mature neuromuscular junction. However, recent research has shown that they are present in muscle tissue during embryonic development, before being largely replaced by acetylcholine receptors later on. This study uses agarose gel electrophoresis to investigate the expression of two classes of ionotropic glutamate receptors at the neuromuscular junction in zebrafish before, during, and after synaptogenesis.
