Overview
Anti-NPY1R (extracellular) Antibody is an antibody targeting Neuropeptide Y receptor type 1, NPYR, NPYY1 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IF, IFC, IHC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Neuropeptide Y receptor type 1, NPYR, NPYY1 (also reported as Neuropeptide Y receptor type 1, NPYR, NPYY1).
- Immunogen/epitope region: 2nd extracellular loop.
- Homology note: Rat - identical; human - 13/14 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
Neuropeptide Y1 receptor (NPY1R) is one out of four receptors (NPY1R, NPY2R, NPY4R and NPY5R) that bind neuropeptide Y (NPY), an abundant neuropeptide in the mammalian central and peripheral nervous systems.NPY1R is part of the β-branch of class A G-protein coupled receptors and likewise, has seven transmembrane domains with an extracellular N-terminus and intracellular C-terminal tail1,2.NPY belongs to a family of gut-brain peptides that demonstrate both hormonal functions by paracrine and endocrine release in the gastrointestinal tract and a neurotransmitter functions in sympathetic ganglia and the CNS. It is highly expressed throughout the brain with particularly high expression in limbic brain areas, such as the hippocampus, amygdala, and hypothalamus3,4. NPY modulates multiple physiological and pathophysiological processes: it increases food intake and reduces fear and anxiety by activating NPY1R1,2.Because of the multiple functions of NPY, NPY1R has great importance in the development and progression of both metabolic and neurological diseases such as diabetes, obesity, breast cancer and bone loss and indeed a number of peptides and small-molecule compounds have been characterized as NPY1R antagonists and have shown clinical potential in the treatment of these pathological states5.
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.
- 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-NR027.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
