Product Overview
This rabbit polyclonal antibody targets caspase-3 (gene CASP3) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 31.6 kDa, and the supplier reports an observed band at about 31 kDa.
Caspase-3 is the major executioner caspase of apoptosis. Activated by initiator caspases such as caspase-8 and caspase-9, it cleaves hundreds of cellular proteins, including PARP1, leading to the typical features of apoptotic cell death. Cleaved (active) caspase-3 is one of the most widely used apoptosis markers in Western blot and immunohistochemistry.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Rat, Mouse) |
|---|
Samples with a confirmed band (WB): rat cardiac muscle tissue, rat liver tissue, rat thymus tissue, MCF-7 cells, SMMC cells, HT1080 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Immunogen
Synthetic peptide based on the sequence of at the C-terminal of human Caspase 3. The peptide sequence is conserved in mouse. It differs from the rat sequence at one residue.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places caspase-3 in the cytoplasm. Tissue expression noted by UniProt (human): Highly expressed in lung, spleen, heart, liver and kidney. 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).
