- Antibody identity: Polyclonal (rabbit origin); Rabbit Ig.
- Conjugate/label: Unconjugated (affects detection chemistry and multiplex compatibility).
- Format: Purified.
- Species reactivity: Human, Mouse.
- Listed applications: WB, IHC-P, FACS (refer to on-page specifications for application-specific guidance).
Biological background
Immunoglobulin J / IGJ / JCHAIN is a protein that is part of the immunoglobulin family, which is responsible for producing antibodies that help the body fight off infections. IGJ is specifically involved in the production and assembly of antibodies, making it a key player in the immune system's defense mechanisms. IGJ plays a crucial role in the immune response by facilitating the assembly of antibodies. When the body encounters a pathogen, such as a virus or bacteria, IGJ helps to bring together different components of antibodies to form a functional immune response. This process is essential for the body to effectively recognize and neutralize foreign invaders. A deficiency in IGJ can lead to impaired immune responses, making individuals more susceptible to infections.
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
- Western blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- Immunohistochemistry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- Flow cytometry: 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).
