Overview
Anti-mGluR3 (extracellular) Antibody is an antibody targeting Metabotropic glutamate receptor 3, GRM3, mGlu3, GPRC1C Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IHC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Metabotropic glutamate receptor 3, GRM3, mGlu3, GPRC1C (also reported as Metabotropic glutamate receptor 3, GRM3, mGlu3, GPRC1C).
- Immunogen/epitope region: Extracellular, N-terminus.
- Homology note: Mouse - identical; human, monkey - 14/15 amino residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- KO-validated: yes (validation context may be assay-dependent).
- Cited use: IFC (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.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
L-glutamate, the major excitatory neurotransmitter in the central nervous system, operates through several receptors that are categorized as ionotropic (ligand-gated cation channels) or metabotropic (G-protein coupled receptors). The metabotropic glutamate receptor family includes eight members (mGluR1-8) that have been divided into three groups based on their sequence homology, pharmacology and signal transduction.Group II of the metabotropic glutamate receptors includes the mGluR2 and mGluR3 receptors. The receptors present the typical G-protein coupled receptor (GPCR) signature topology: seven transmembrane domains with a large extracellular N-terminus that contains the glutamate binding site, and an intracellular C-terminus.1,2 mGluR2 and mGluR3 are coupled to Gi/G0 and hence inhibit cAMP formation following receptor activation.1,2mGluR3 is expressed in neurons and glia in many brain regions including the cerebral cortex, hippocampus and brain stem.
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.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
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.
- Conceptual control: KO/KD samples provide orthogonal support for target assignment when available.
- Provided control suggestions: Negative control: BLP-GC012.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
