Overview
Anti-GABA(A) α2 Receptor Antibody is an antibody targeting γ-Aminobutyric acid receptor type A subunit α2, GABRA2 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IHC, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: γ-Aminobutyric acid receptor type A subunit α2, GABRA2 (also reported as γ-Aminobutyric acid receptor type A subunit α2, GABRA2).
- Immunogen/epitope region: 2nd intracellular loop.
- Homology note: Mouse, human, bovine - identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Cited use: IHC (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
GABA (γ-aminobutyric acid) is the major inhibitory neurotransmitter in the brain. Its production, release, reuptake and metabolism occur in the nervous system.1 The GABA transmitter interacts with two major types of receptors: ionotropic GABAA (GABAAR) and metabotropic GABAB receptors. The GABAAR belong to the ligand gated ion channel superfamily.2 The GABAAR, is a heteropentamer, with all of its five subunits contributing to the pore formation.
Research relevance and current trends
- Mapping receptor/channel localization across neuronal subtypes and subcellular compartments.
- Linking trafficking or surface expression changes to activity-dependent signaling and plasticity.
- Using KO/KD or blocking-peptide concepts to strengthen antibody-based target assignment.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-GA002.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
