- Antibody type: Mouse, clone C7, Mouse IgG1.
- Format: Purified; Protein G affinity.
- Reported/predicted localization: Secreted.
- Species reactivity: tested: Human.
- Immunogen (if provided): Human Elafin/Skalp recombinant protein (amino acids A61-Q117) was used as the immunogen for the Elafin antibody..
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
Elafin, also known as peptidase inhibitor 3 or skin-derived antileukoprotease (SKALP), is a protein that in humans is encoded by the PI3 gene. This gene encodes an elastase-specific inhibitor that functions as an antimicrobial peptide against Gram-positive and Gram-negative bacteria, and fungal pathogens. The protein contains a WAP-type four-disulfide core (WFDC) domain, and is thus a member of the WFDC domain family. Most WFDC gene members are localized to chromosome 20q12-q13 in two clusters: centromeric and telomeric. And this gene belongs to the centromeric cluster. Expression of this gene is upgulated by bacterial lipopolysaccharides and cytokines.
For curated annotations (gene/protein naming, domains, isoforms, and pathway links) for ELAFIN, consult primary databases such as UniProt, NCBI Gene, and Ensembl.
Research relevance and current trends
- Context-dependent expression studies: researchers often examine ELAFIN 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.
- ELISA-based detection or quantification in research assays (format- and epitope-dependent).
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).
