- Format: Antigen affinity purified.
- Species reactivity: Human, Mouse, Rat.
- Listed applications: WB, IHC-P, IF, Direct ELISA (refer to on-page specifications for application-specific guidance).
Biological background
B-cell CLL/lymphoma 9 like is a protein that in humans is encoded by the BCL9L gene. It is mapped to 11q23.3. Bcl-9 (B-cell lymphoma 9; also Protein legless homolog) is a transcriptional regulator that belongs to the Bcl-9 family of proteins. It is expressed in multiple tissues and serves to recruit Pygopus to the Wnt-pathway beta -catenin-TCF complex in the nucleus. Bcl-9 and Bcl-9-2 are considered evolutionary duplicates of Legless that perform the same task with different regulation. Human Bcl-9 is 1426 amino acids (aa) in length. It contains one phosphothreonine and three phosphoserine sites that have been identified so far, two poly-Pro regions (aa 514?517 and 970?973), and one poly-Ala segment (aa 900?903). There is one potential alternate start site at Met27, and a variant isoform exists that shows a four aa substitution for aa 1391?1426. Over aa 1009?1328, human Bcl-9 is 96% aa identical to mouse Bcl-9.
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.
- Immunofluorescence: 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).
