- Conjugate/label: Unconjugated (affects detection chemistry and multiplex compatibility).
- Format: Antigen affinity purified.
- Species reactivity: Mouse, Rat.
- Listed applications: IHC-P, Direct ELISA (refer to on-page specifications for application-specific guidance).
Biological background
CXCR5 (Chemokine CXC Motif Receptor 5), also known as BLR1 (Burkitt lymphoma receptor 1) and MDR15 (Monocyte derived receptor 15), is a G protein-coupled seven transmembrane receptor for chemokine CXCL13 (also known as BLC) and belongs to the CXC chemokine receptor family. In humans, the CXC-R5 protein is encoded by the CXCR5 gene. The gene plays an essential role in B cell migration. Reif et al.(2002) concluded that their findings defined the mechanism of B-cell relocalization in response to antigen, and established that cell position in vivo can be determined by the balance of responsiveness to chemo-attractants made in separate but adjacent zones. Chan et al.(2003) investigated the expression of chemokines and chemokine receptors in eyes with primary intraocular B-cell lymphoma (PIOL).
Research relevance and current trends
- Comparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).
- Subcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.
- Integration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.
Common research applications
- Immunohistochemistry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- ELISA: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
Interpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.
Notes for experimental interpretation
- Isoforms and PTMs: many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands/signals accordingly.
- Epitope context: binding can depend on protein conformation and sample processing; region information in the title/immunogen can help anticipate what may be detected.
- Species differences: predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.
- Control concepts: include negative controls (no-primary/isotype), and where possible genetic controls (KO/KD) or independent antibodies to strengthen conclusions.
Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
