Overview
Anti-CRF2/CRHR2 (extracellular) Antibody is an antibody targeting Corticotropin-releasing factor receptor 2, CRF-R-2, CRF2 receptor beta isoform, Corticotropin-releasing hormone receptor 2, CRH receptor 2 variant B 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: Corticotropin-releasing factor receptor 2, CRF-R-2, CRF2 receptor beta isoform, Corticotropin-releasing hormone receptor 2, CRH receptor 2 variant B (also reported as Corticotropin-releasing factor receptor 2, CRF-R-2, CRF2 receptor beta isoform, Corticotropin-releasing hormone receptor 2, CRH receptor 2 variant B).
- Immunogen/epitope region: Extracellular, N-terminus.
- Homology note: Mouse - 14/15 amino acid residues identical; human - 13/15 amino acid residues 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
CRFR2 is a G-protein coupled receptor for CRF (corticotropin-releasing factor) and urocortins UCN1, UCN2, and UCN3. The receptor-ligand interaction causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and down-stream effectors, such as adenylate cyclase, leading to increased intracellular cAMP levels1.CRFR2 is expressed in the CNS and peripheral tissues including the heart, vasculature, skeletal muscle, and gastrointestinal tract, and it plays a central role in coordinating endocrine, autonomic, and behavioral responses to stress1. CRFR2 ligands, the UCN peptides, exert actions in central and peripheral tissues where they modulate cardiovascular, immune, gastrointestinal, and reproductive functions in response to stress2.
Research relevance and current trends
- Comparing target expression across perturbations, genotypes, or treatment conditions.
- Interpreting localization shifts alongside pathway or phenotypic readouts.
- Using orthogonal controls (KO/KD, peptide competition, isotype concepts) to support conclusions.
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-CR052.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
