GABA A Receptor beta 3 Antibody

• Background:

  Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system, causing a hyperpolarization of the membrane through the opening of a Cl- channel associated with the GABAA-Receptor (GABAA-R) subtype. GABAA-Rs are important therapeutic targets for a range of sedative, anxiolytic, and hypnotic agents and are implicated in several diseases including epilepsy, anxiety, depression, and substance abuse. The GABAA-R is a multimeric subunit complex. To date six alphas, four betas and four gammas, plus alternative splicing variants of some of these subunits, have been identified. Injection in oocytes or mammalian cell lines of cRNA coding for alpha and beta subunits results in the expression of functional GABAA-Rs sensitive to GABA. However, coexpression of a gamma subunit is required for benzodiazepine modulation. The various effects of the benzodiazepines in brain may also be mediated via different alpha subunits of the receptor. Lastly, phosphorylation of beta subunits of the receptor has been shown to modulate GABAA-R function.

• Applications Notes:

  GABAA Receptor antibody is specific for the 51 to 56k GABAA-Receptor β3-Subunit in rat brain membrane fractions. Antibody dilutions and tissue load should be based on tissue type and expected expression level. Initial recommended range of dilutions: 1:1000 to 1:2000. Applications include Dot Blots (DB) and Western Blot (WB) . Suitability for Immunohistochemistry (IHC) not yet determined. When internally tested under ideal conditions the working dilutions were 1:1000 for DB and WB.
