    Fusion protein of MBP with the amino acid sequence representing the cytosolic loop of the rat GABA-A receptor beta 2 subunit.



Our Abpromise guarantee covers the use of ab8340 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IP Use at an assay dependent dilution. Use 15µg for 150 µl tissue (68% of all GABA-A receptors in dodecylsulfate extracts of rat forebrains).
WB 1/1000. By Western blot, this antibody detects an 50 - 53 kDa protein, corresponding to the expected molecular weight of GABA A receptor beta 2 subunit.


  • 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.
  • Tissue specificity
    Isoform 1 and isoform 2 show reduced expression in schizophrenic brain. Isoform 3 shows increased expression in schizophrenic and bipolar disorder brains while isoform 4 shows reduced expression.
  • Sequence similarities
    Belongs to the ligand-gated ion channel (TC 1.A.9) family. Gamma-aminobutyric acid receptor (TC 1.A.9.5) subfamily. GABRB2 sub-subfamily.
  • Cellular localization
    Cell junction > synapse > postsynaptic cell membrane. Cell membrane.

Thank you for your inquiry.

Unfortunately, we are not able to release the immunogen sequence for these particular antibodies as it is proprietary information. Unfortunately, we do not have the corresponding peptides for sale, either.
