Description
General description
The neurotransmitter GABA (gamma-aminobutyric acid) binds to specific transmembrane receptors in the plasma membrane of both pre- and postsynaptic neurons. Three general classes of GABA receptors are known: GABAA and GABAC (ionotropic) receptors and GABAB (metabotropic) receptors. The GABAA (gamma-Aminobutyric Acid type A) receptor is a multiprotein complex that acts as a ligand-gated chloride channel. These receptors are hetero-oligomers, for which 6 subunits are currently known (a, b, g, d, e and r). There are at least 3 different isoforms of the beta subunit, and receptor subunit expression varies during development. Additionally, GABAA receptors are important in regulating the reinforcing properties of alcohol, and expression of the alpha1 and beta 2/3 subunits increase upon chronic exposure to alcohol, and may be potential therapeutic targets for alcohol dependency. The beta 2 subunit is required for receptor assembly and surface expression, while mice with an inactivated beta3 subunit exhibit epilepsy and cleft palate.
Varies
Immunogen
Affinity-purified GABAA receptor isolated from bovine brain. Clone 62-3G1
Application
Anti-GABA A Receptor β2/3 Antibody, is an antibody against GABA A Receptor β2/3 for use in WB, IP, IH.
Immunoprecipitation: 4 μg of a previous lot immunoprecipitated the GABAA Receptor β2 and β3 subunits from 500 μg of rat brain microsomal tissue extract. Due to interference of the IgG heavy chain, the immunoprecipitated GABAA receptor complex was confirmed using a polyclonal anti-GABAA receptor α1 subunit (Catalog # 06-868).
Immunohistochemistry: This antibody has been reported to detect the GABAA Receptor β2 and β3 subunits in paraffin embedded and frozen rat brain sections which had been fixed with 4% paraformaldehyde or 0.1% glutaraldehyde and permeabilized with Triton X-100.
