Immunofluorescent analysis of Nicotinic Acetylcholine Receptor using Anti-Nicotinic Acetylcholine Receptor Monoclonal Antibody (88B) (Product# MA3-043) shows staining in Neuro-2a Cells. Nicotinic Acetylcholine Receptor staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with or an antibody recognizing Nicotinic Acetylcholine Receptor (Product# MA3-043) at a dilution of 1:100 over night at 4 °C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product# 35503, Goat Anti-Mouse). Images were taken at 60X magnification.

MA3-043 detects nicotinic acetylcholine receptor (nAChR) gamma and delta subunits in torpedo and the delta subunit in mouse, human, rat, chicken and frog. This antibody does not detect the alpha 1 and beta 1 subunits.
MA3-043 has been successfully used in Western blot, immunohistochemistry and immunoprecipitation procedures. By Western blot, this antibody detects a 60 kDa protein representing the gamma subunit and a 65 kDa protein representing the delta subunit from torpedo skeletal muscle homogenates. Under non-reducing conditions the delta subunit migrates mostly as a dimer of ~130 kDa. Immunohistochemical staining of nAChR in rat skeletal muscle with MA3-043 results in strong staining of the motor endplate.
In Immunohistochemical staining, cryostat or permeabilization of the sections is recommended due to the reactivity of this antibody with the cytoplasmic side of the receptor.
The MA3-043 antigen is purified Torpedo californica acetylcholine receptor.
Acetylcholine receptors (AChRs) mediate synaptic transmission at the neuromuscular junction. The channel-linked AChR that mediates rapid, excitatory actions of acetylcholine is called nicotinic AChR (nAChR) because it can be activated by nicotine. The non-channel linked AChR that medicates the slow actions of acetylcholine, which can be either inhibitory or excitatory, is called muscarinic AChR (mAChR) because it can be activated by muscarine.
The nAChRs fall into two subclasses, the muscle-type and the neuronal-type. The muscle-type receptor is a pentameric glycoprotein of five membrane spanning subunits, (2 alpha 1"e;s, beta 1, gamma or epsilon and delta) which form a ligand gated ion channel. The neuronal nAChR is also a pentamer, but unlike the muscle-type, is made up of only two general types of subunits, alpha and beta of which multiple subtypes have been described (alpha 2 to alpha 8 and beta 2 to beta 4).
