Overview
Anti-β1-Adrenergic Receptor (extracellular)-ATTO Fluor-488 Antibody is an antibody targeting Beta-1 adrenoceptor, Beta-1 adrenoreceptor, ADRB1, ADRB1R, B1AR 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: Beta-1 adrenoceptor, Beta-1 adrenoreceptor, ADRB1, ADRB1R, B1AR (also reported as Beta-1 adrenoceptor, Beta-1 adrenoreceptor, ADRB1, ADRB1R, B1AR).
- Immunogen/epitope region: 2nd extracellular loop.
- Homology note: Mouse, human - 14/15 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- Lot quality control (as provided): Western blot analysis (unlabeled antibody, #AAR-023), and immunohistochemistry (labeled antibody)..
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
- Conjugate/format: 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. (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
β-Adrenergic receptors control key physiological functions through signals encoded by catecholamine hormones and neurotransmitters to activate intracellular signaling pathways. These receptors belong to the amine receptor cluster of rhodopsin-like family of G-protein coupled receptors (GPCRs).The β1 adrenergic receptor (β1AR) is comprised of an extracellular N-terminus, seven membrane spanning loops (TM1-7) and an intracellular C-terminus1.β1AR couples to the stimulatory G protein Gs and thereby activates adenylyl cyclase. β1AR also couples to the inhibitory G protein Gi and can induce G protein independent signaling.
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.
- Provided control suggestions: Negative control: RIC-001-AG.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
