GABA (A) alpha2 Receptor Antibody

Affinity purified polyclonal antibody

  • WB - GABA (A) alpha2 Receptor Antibody AG1278-050
    Western blot analysis of rat brain membranes: 1. Anti-GABA(A) α2 Receptor antibody (#AG1278), (1:200).   
    2. Anti-GABA(A) α2 Receptor antibody, preincubated with the control peptide antigen.
  • IHC - GABA (A) alpha2 Receptor Antibody AG1278-050
    Expression of GABA(A) α2 Receptor in mouse cerebellum Immunohistochemical staining of mouse formalin-fixed frozen cerebellum sections with Anti-GABA(A) α2 Receptor antibody (#AG1278).  The receptor subunit is localized mainly on the soma of Purkinje cells.  Staining with mouse anti-parvalbumin (red) suggests that GABA(A) α2 Receptor subunit is restricted to a sub-region of the Purkinje cell.

GABA (γ-aminobutyric acid) is the major inhibitory neurotransmitter in the brain. Its production, release, reuptake and metabolism occur in the nervous system.1  The GABA transmitter interacts with two major types of receptors: ionotropic GABAA (GABAAR) and the metabotropic GABAB) receptors. The GABAAR belong to the ligand gated ion channel superfamily.2  The GABAAR, is a heteropentamer, with all of its five subunits contributing to the pore formation. To date, eight subunit isoforms were cloned: α, β, γ, δ, ε, π, θ, and ρ.1 Six α subunit isoforms were described to exist in mammals (α1-α6). The native GABAA receptor, in most cases, consists of 2α, 2β and 1γ submit. The α subunit is the most common subunit and is expressed ubiquitously. It determines the affinities for allosteric ligands shown by GABAAR.  The α2-subunit mRNA is strongly expressed only in the hippocampus and the hypothalamus. It occurs very early in rat brain development and declines in adulthood.  The failure to complete the normal transition between the a-subunits that are highly expressed in early development (α2, α3, α5) to those expressed in adulthood (α1) might play a major role in the development of temporal lobe epilepsy.3
