Product Overview
Clone DCB-3 is a rabbit monoclonal antibody that recognizes caspase-1 (gene CASP1) in human and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 45.2 kDa, and the supplier reports an observed band at about 35–48 kDa.
Caspase-1 is the inflammatory caspase activated by canonical inflammasomes such as NLRP3, NLRC4 and AIM2. Once active, it processes pro-IL-1β and pro-IL-18 into mature cytokines and cleaves gasdermin D to trigger pyroptosis, a lytic, inflammatory form of cell death. It is a central readout in innate immunity and inflammation research.

Validated Applications
| Western blot | 1:500–1:2000 |
|---|---|
| Immunohistochemistry | 1:50–1:200 |
Samples with a confirmed band (WB): human THP-1 cells, human SIHA cells, human A431 cells, human RT4 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1: 500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human liver tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Immunogen
Synthetic peptide based on the sequence of human caspase-1.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places caspase-1 in the cytoplasm and cell membrane. Tissue expression noted by UniProt (human): Expressed in larger amounts in spleen and lung. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

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).
