Immunohistochemistry (IHC) is vital for the study of NMJ biology because it enables visualization of the NMJ. This is accomplished by using antibodies that recognize the neuronal membrane (e.g., HRP), the presynapse (e.g., CSP, SYT), and/or the postsynapse (e.g., DLG). Signaling molecules, structural proteins, or novel proteins of interest can also be stained. Then, genes can be mutated or missexpressed, and IHC can detect perturbation of synaptic structure and/or neuronal signaling.
The NMJ o...

drosophila larval nmj immunohistochemistry

The Drosophila neuromuscular junction (NMJ) is an established model system used for the study of synaptic development and plasticity. The widespread use of the Drosophila motor system is due to its high accessibility. It can be analyzed with single-cell resolution. There are 30 muscles per hemisegment whose arrangement within the peripheral body wall are known. A total of 31 motor neurons attach to these muscles in a pattern that has high fidelity. Using molecular biology and genetics, one can create transgenic animals or mutants. Then, one can study the developmental consequences on the morphology and function of the NMJ. Immunohistochemistry can be used to clearly image the components of the NMJ. In this article, we demonstrate how to use antibody staining to visualize the Drosophila larval NMJ.
