Overview
Anti-Human CX3CR1 (extracellular) Antibody is an antibody targeting Fractalkine Receptor, CX3C chemokine receptor 1, C-X3-C CKR-1, C-X3-C motif chemokine receptor 1, GPR13, CMKBRL1, GPRV28, V28, G-protein coupled receptor 13, CCRL1, Beta chemokine receptor-like 1 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: Fractalkine Receptor, CX3C chemokine receptor 1, C-X3-C CKR-1, C-X3-C motif chemokine receptor 1, GPR13, CMKBRL1, GPRV28, V28, G-protein coupled receptor 13, CCRL1, Beta chemokine receptor-like 1 (also reported as Fractalkine Receptor, CX3C chemokine receptor 1, C-X3-C CKR-1, C-X3-C motif chemokine receptor 1, GPR13, CMKBRL1, GPRV28, V28, G-protein coupled receptor 13, CCRL1, Beta chemokine receptor-like 1).
- Immunogen/epitope region: Extracellular, N-terminus.
- Homology note: Human only (informative for cross-species interpretation).
- Species reactivity (as provided): Human.
- Specificity statement (as provided): The antibody will not recognize the protein from rat or mouse samples..
- 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.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
CX3C-chemokine receptor 1 (CX3CR1) is a 368 amino acid (aa) protein that contains seven-transmembrane domains and belongs to the family of G protein coupled receptors1.CX3CR1 has a central role in adhesion and chemotaxis through binding to its ligand, fractalkine CX3C chemokine ligand 1, (CX3CL1). The major role of CX3CR1 in immune cells is to recognize and enter inflamed tissue according to CX3CL1 gradient and initiate the innate immune system2. The receptor-ligand axis also mediates the crosstalk between glial cells and neurons by direct or indirect ways in the central nervous system (CNS)3.
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
- 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-CR059.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
