Our Abpromise guarantee covers the use of ab26055 in the following tested applications.

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

应用 Ab评论 说明
WB Use a concentration of 0.5 µg/ml. Predicted molecular weight: 50 kDa.Can be blocked with GABA A receptor pi peptide (ab206287). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use at an assay dependent concentration.
ELISA 1/312500.
ICC/IF Use at an assay dependent concentration. PubMed: 22700823


  • 功能
    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. In the uterus, the function of the receptor appears to be related to tissue contractility. The binding of this pI subunit with other GABA(A) receptor subunits alters the sensitivity of recombinant receptors to modulatory agents such as pregnanolone.
  • 组织特异性
    Most abundant in the uterus, also expressed in lung, thymus and prostate.
  • 序列相似性
    Belongs to the ligand-gated ion channel (TC 1.A.9) family. Gamma-aminobutyric acid receptor (TC 1.A.9.5) subfamily. GABRP sub-subfamily.
  • 细胞定位
    Cell junction > synapse > postsynaptic cell membrane. Cell membrane.
