Overview
Anti-Neuropilin-1 (NRP1) (extracellular)-FITC Antibody is an antibody targeting Vascular endothelial cell growth factor 165 receptor, VEGF165R, CD304 Polyclonal raised in Rabbit (Fluorescein isothiocyanate (FITC)). This antibody is commonly used in FC to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Vascular endothelial cell growth factor 165 receptor, VEGF165R, CD304 (also reported as Vascular endothelial cell growth factor 165 receptor, VEGF165R, CD304).
- Immunogen/epitope region: Extracellular, N-terminus.
- Homology note: Rat, mouse - identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Lot quality control (as provided): Western blot analysis (Unlabeled antibody, #ANR-063), and direct flow cytometry (Labeled antibody)..
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
- Conjugate/format: Fluorescein isothiocyanate (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
Neuropilins (NRPs) are co-receptors for class 3 semaphorins, polypeptides with key roles in axonal guidance, and for members of the VEGF (vascular endothelial growth factor) family of angiogenic cytokines.Neuropilin 1 (NRP1) is a transmembrane glycoprotein and comprises a large extracellular region containing multiple domains, a single transmembrane domain and a small cytoplasmic domain, also with a number of protein interacting domains.Class 3 semaphorins bind NRP1 (and NRP2) with different, and partially overlapping, specificities and affinities. Plexin A1 and Plexin A2 are the major signaling receptors for class 3 semaphorins, and complex with NRPs and semaphorins to form a holoreceptor essential for mediating effects of semaphorins on growth-cone collapse and axonal guidance in neurogenesis. The major VEGF-A signaling receptor, VEGF receptor 2, forms complexes with NRP1 and is important for optimal VEGFR2 signaling and function in endothelial cells.Targeted disruption of the NRP1 gene has demonstrated an essential dual role of these molecules in neurogenesis and cardiovascular development.
Research relevance and current trends
- Profiling immune-marker expression across cell subsets with single-cell or flow-based readouts.
- Connecting receptor/ligand levels to activation state and cytokine programs.
- Applying genetic perturbation or orthogonal assays to support specificity and interpretation.
Common research applications
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
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-F.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
