GABA A (γ-aminobutyric acid-type A) receptors are members of the cysteine-loop family of neurotransmitter-gated ion channels.
GABA binding to A-type receptors induces anion-selective ion channel opening.
These receptors are the principal fast inhibitory neurotransmitter receptors in the CNS.
GABA A receptors are heteropentamer combinations of seven subunit types; aplha, beta, γ, δ, ε, θ, and π.
Three subunits, alpha, beta, and γ, have at least three separate gene products in mammals, and typical GABA A receptors have some combination of aplha, beta and γ subunits.
The rat alpha 4 isoform is a 67kD, 517 amino acid (aa), 4 transmembrane protein with two terminal extracellular regions.
The ligand-binding region is in the N-terminus (aa 14-221).
The aplha 4 subunit is unusual in that it does not seem to preferentially form channel complexes with the γ subunit.
In hippocampal neurons, alpha 4 subunits apparently form GABA receptors that do not cluster, but exist in diffuse networks in nonsynaptic membrane.
Applications:Suitable for use in Western Blot.
Other applications not tested.
Recommended Dilution:Western Blot: 1:1000.

Optimal dilutions to be determined by the researcher.
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20°C.
Aliquots are stable for at least 12 months at -20°C.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
