Overview
Anti-GRIK5 (GluK5) (extracellular) Antibody is an antibody targeting Glutamate receptor ionotropic kainate 5, Glutamate receptor KA-2, KA2 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: Glutamate receptor ionotropic kainate 5, Glutamate receptor KA-2, KA2 (also reported as Glutamate receptor ionotropic kainate 5, Glutamate receptor KA-2, KA2).
- Immunogen/epitope region: Extracellular, N-terminus.
- Homology note: Human, mouse - identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- 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.
- Conjugate/format: Unconjugated (may affect detection channel and background).
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
There are three glutamate receptor superfamilies defined by the specific agonist binding to them - NMDA, AMPA and kainate.Several types of kainate receptors have been cloned and classified. Two of these have a high affinity to kainate (GLUK1 and GLUK2), while GLUK5, as well as other members of the family, have a lower affinity1. GLUK5, GLUK6 and GLUK7 have a 75-80% identical amino acid sequence making them a separate subfamily from the other kainate receptors.The GLUK5 receptor, similar to its subfamily members, is a ligand-gated ion channel.
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-GC042.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
