Overview
Anti-GluR2 (GluA2) (extracellular)-ATTO Fluor-488 Antibody is an antibody targeting AMPA receptor 2, Glutamate receptor 2, Ionotropic glutamate receptor 2, AMPA-selective glutamate receptor 2, GRIA2, GluR-B, GluR-K2 Polyclonal raised in Rabbit (ATTO-488. Maximum absorption 501 nm; maximum fluorescence 523 nm. The fluorescence is excited most efficiently in the 480 - 515 nm range. This label is analogous to the dye fluorescein isothiocyanate (FITC) and can be used with filters used to detect FITC.). This antibody is commonly used in IF, IHC to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: AMPA receptor 2, Glutamate receptor 2, Ionotropic glutamate receptor 2, AMPA-selective glutamate receptor 2, GRIA2, GluR-B, GluR-K2 (also reported as AMPA receptor 2, Glutamate receptor 2, Ionotropic glutamate receptor 2, AMPA-selective glutamate receptor 2, GRIA2, GluR-B, GluR-K2).
- Immunogen/epitope region: Extracellular, N-terminus.
- Homology note: Mouse - identical; human - 14/15 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- KO-validated: yes (validation context may be assay-dependent).
- Cited use: IHC (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis (unlabeled antibody, #AGC-005), and immunohistochemistry (labeled antibody)..
- 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
AMPA receptors are members of the glutamate receptor family of ion channels that also include the NMDA and kainate receptors. The three subfamilies are named after the original synthetic agonists that were identified as selective ligands of each subfamily.The α-amino-3-hydroxy-5-methyl-4-isoazolepropionic acid (AMPA) receptor subfamily includes four members, AMPA1-AMPA4, that are also known as GluR1-GluR4, respectively.The functional AMPA channel is believed to be a tetramer. Most neuronal AMPA receptors are heterotetramers composed of AMPA1 plus AMPA2 or AMPA2 plus AMPA3, although homotetramers are also found.AMPA receptors are permeable to Na+, K+, and Ca2+ cations.
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
- 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.
- Conceptual control: KO/KD samples provide orthogonal support for target assignment when available.
- Provided control suggestions: Negative control: RIC-001-AG.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
