Affinity purified polyclonal antibody

  • WB - GABA (A) gamma2 Receptor (extracellular) Antibody AG1275-050
    Western blot analysis of rat brain membranes: 1. Anti-GABA(A) γ2 Receptor (extracellular) antibody (#AG1275), (1:200).  
    2. Anti-GABA(A) γ2 Receptor (extracellular) antibody, preincubated with the control peptide antigen.
  • ICC - GABA (A) gamma2 Receptor (extracellular) Antibody AG1275-050
    TNF-α-induced downregulation of surface GABA(A) γ2 Receptor Immunocytochemical staining of rat living hippocampal neurons. A. Extracellular staining of cells using Anti-GABA(A) γ2 Receptor (extracellular) antibody (#AG1275), (1:100). Representative images from time course experiments with cultured neurons undergoing TNF-α treatment ranging from 10 min to 6 h in duration. Results show a rapid downregulation in surface levels of the γ2 subunit in response to TNF-α. B. Quantification data of surface γ2 cluster area, over the 6 h time course of TNF-α treatment (n = 120 –158 images per time point; one-way ANOVA, Tukey’s post hoc test, **p < 0.01, ***p < 0.001).

The neurotransmitter GABA (γ-aminobutyric acid) inhibits the activity of signal-receiving neurons by interacting with the GABAA receptor on these cells.1 There are two major types of   GABA receptors: the ionotropic GABAA (GABAA R) and the metabotropic GABAB receptors.   GABAA R belongs to the ligand gated ion channel superfamily.1,2  It 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 The native GABAA receptor, in most cases, consists of 2α, 2β and 1γ subunit. Three γ subunits genes have been identified in mammals.  The binding of GABA to its GABAA receptor results in conformational changes that open a Cl- channel, producing an increase in membrane conductance, resulting in inhibition of neural activity.2,3  Recently, a genetic linkage between familial epilepsy syndrome and mutations in the γ2 subunit of the GABAA receptor have been demonstrated.4,5
