Overview
Anti-Adenosine A3 Receptor (extracellular) Antibody is an antibody targeting ADORA3, A3AR, Adenosine Receptor A3 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IFC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: ADORA3, A3AR, Adenosine Receptor A3 (also reported as ADORA3, A3AR, Adenosine Receptor A3).
- Immunogen/epitope region: Extracellular, 2nd loop..
- Homology note: Rat - 10 out of 13 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- Specificity statement (as provided): The antibody will not recognize adenosine A3 receptor from human samples..
- 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
Adenosine is an endogenous nucleoside generated locally in tissues under conditions of hypoxia, ischemia, or inflammation. It modulates a variety of physiological functions in many tissues including the brain and heart.1,2 Adenosine exerts its action via four specific adenosine receptors (also named P1 purinergic receptors): Adenosine A1 Receptor (A1AR), Adenosine A2A Receptor (A2AAR), Adenosine A2B Receptor (A2BAR), and Adenosine A3 Receptor (A3AR). The various adenosine receptors can be distinguished on the basis of their distinct molecular structures, distinct tissue distributions, and differential selectivity for adenosine analogs.1-4 All are integral membrane proteins and are members of the G protein-coupled receptor superfamily.
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.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- 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.
- Provided control suggestions: Negative control: BLP-AR035.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
