Specific for the ~55k alpha 5 -subunit of the GABA A receptor in Western blots of rat brain membraine fractions. Also recognizes the mouse alpha 5 of GABA A -R.

Affinity Purified (Prepared from rabbit serum by affinity purification using a column to which the fusion protein immunogen was coupled.)

100 ul in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

For long term storage -80 degree C is recommended, but shorter term storage at -20 degree C is also acceptable as aliquots may be taken without freeze/thawing due to the presence of 50% glycerol. Stock solutions are stable for a minimum of 1 yr at -20 degree C.

Western Blot (WB); Dot Blots (DB). Suitability for Immunohistochemistry (IHC) not yet determined.

Quality Control: Dot Blots & Western blots performed on each lot. Working Dilutions: DB: 1:1000. WB: 1:1000

Antigen: Fusion protein from the cytoplasmic loop of the alpha5-subunit of rat GABAA receptor. Immunogen Information: Fusion protein from the cytoplasmic loop of the alpha 5 subunit. Immunogen Species: Rat

Reactivity Assumed Based on 100% Sequence Homology: Bovine chicken, canine, human, mouse non-human primate, zebra fish. Species Reactivity Note: The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, canine, chicken, human, mouse, non-human primate and zebra fish based on the fact that these species have 100% homology with the amino acid sequence used as antigen. Biological Significance: 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 (Olsen and Tobin, 1990; Whiting et al., 1999; Ogris et al., 2004). 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 (McKernan et al., 2000; Mehta and Ticku, 1998; Ogris et al., 2004; Pöltl et al., 2003).

subunit of the GABAA receptor; may be part of distinct GABAA receptors within the olfactory bulb [RGD, Feb 2006]

Function: GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel. Subunit structure: Generally pentameric. There are five types of GABA(A) receptor chains: alpha, beta, gamma, delta, and rho. Subcellular location: Cell junction synapse postsynaptic cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein. Sequence similarities: Belongs to the ligand-gated ion channel (TC 1.A.9) family. Gamma-aminobutyric acid receptor (TC 1.A.9.5) subfamily. GABRA5 sub-subfamily. [View classification]
