The information above helps you match the antibody format to your assay context, interpret species-dependent differences, and anticipate how epitope context (isoforms, PTMs, or conformational state) may influence signal.
Biological background
Transmembrane activator and CAML interactor (TACI), also known as tumor necrosis factor receptor superfamily member 13B (TNFRSF13B) is a protein that in humans is encoded by the TNFRSF13B gene. The protein encoded by this gene is a lymphocyte-specific member of the tumor necrosis factor (TNF) receptor superfamily. It interacts with calcium-modulator and cyclophilin ligand (CAML). The protein induces activation of the transcription factors NFAT, AP1, and NF-kappa-B and plays a crucial role in humoral immunity by interacting with a TNF ligand. This gene is located within the Smith-Magenis syndrome region on chromosome 17.
For curated annotations (gene/protein naming, domains, isoforms, and pathway links) for TACI, consult primary databases such as UniProt, NCBI Gene, and Ensembl.
Research relevance and current trends
- Context-dependent expression studies: researchers often examine TACI abundance and localization across perturbations (genetic, pharmacologic, or environmental) to connect phenotype to molecular changes.
- Reagent reproducibility: there is growing emphasis on antibody specificity checks using orthogonal approaches (e.g., genetic perturbation or independent antibodies) and transparent reporting of clone/lot information.
- Multi-modal datasets: antibody-based readouts are increasingly combined with transcriptomics and imaging to relate protein-level measurements to cell-state transitions.
Common research applications
- Immunohistochemistry for spatial mapping of target expression across tissues and cell types.
When comparing conditions, interpret changes in signal in the context of sample composition, expected localization, and any known isoform complexity for the target.
Notes for experimental interpretation
- Isoforms and PTMs: alternative splicing or post-translational modifications can change epitope accessibility and apparent molecular weight; interpret bands/signals accordingly.
- Cross-reactivity and matrix effects: background binding can vary by sample type, species, and blocking/detection chemistries; include appropriate negative controls.
- Control concepts: where feasible, use genetic perturbation (KO/KD/overexpression), orthogonal assays, or independent antibodies to support specificity claims.
Antibody considerations: Polyclonal reagents may recognize multiple epitopes and can increase sensitivity but may show broader binding profiles, while monoclonal clones provide a single-epitope readout that can improve consistency across experiments. If a conjugate is listed, the antibody supports more direct detection workflows; otherwise, it is typically used with a compatible secondary antibody.
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).
