Overview
Anti-PACAP Receptor 1 (PAC1) Antibody is an antibody targeting PACAP type I receptor, Pituitary adenylate cyclase-activating polypeptide type I receptor, PACAP-R1, ADCYAP1R1 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IF, IHC, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: PACAP type I receptor, Pituitary adenylate cyclase-activating polypeptide type I receptor, PACAP-R1, ADCYAP1R1 (also reported as PACAP type I receptor, Pituitary adenylate cyclase-activating polypeptide type I receptor, PACAP-R1, ADCYAP1R1).
- Immunogen/epitope region: Intracellular, C-terminus.
- Homology note: Mouse - identical; human - 12/14 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.
- 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
Pituitary adenylate cyclase-activating polypeptide (PACAP, encoded by ADCYAP1) belongs a superfamily of structurally related peptide hormones, which include vasoactive intestinal peptide (VIP), glucagon, glucagon-like peptides, secretin, gastric inhibitory peptide and growth hormone-releasing hormone.PACAP acts through PAC1, VPAC1 and VPAC2, initiating multiple signaling pathways1. PAC1 is a class B member of the G-protein coupled receptors (GPCRs) superfamily. Class B receptors are differentiated from Class A by a relatively large N-terminal ectodomain that is crucial to ligand recognition2.PAC1R is mainly expressed on smooth muscle cells, neurons, endothelial cells and peritoneal macrophages3.PAC1R is associated with posttraumatic stress disorder (PTSD) symptoms and psychophysiological markers of fear and anxiety4.PAC1 receptor null mice demonstrate reduced anxiety-like behavior5.
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.
- 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: BLP-VR003.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
