native and denatured α7 subunit (amino acids 380-400, binds α-bungarotoxin) of the nicotinic acetylcholine receptor from chicken and the denatured α7 subunit from rat.

General description

Nicotinic acetylcholine receptors (nAChRs) function as ligand-gated channels that modulate endoplasmic reticulum stress and neurotransmitter release. These receptors also control synaptic signaling in ganglia and muscles. The α7 form of nAChR is expressed in mitochondria and regulates Ca2+ transport and the release of cytochrome c. When expressed in non-excitable cells, α7 nAChR mediates cell growth and survival
Monoclonal anti-nicotinic acetylcholine receptor ((α7) subunit) antibody is specific for native and denatured α7 subunits in chick, as well as for the denatured α7 subunits in rats and humans. The antibody does not bind well to the native form of the mammalian α7 subunit. The product can be used in chick, rat and human tissues.

Physical form

Solution in 20 mM Na3PO4, pH 7.2, containing 150 mM NaCl and 0.05% sodium azide.
