Scientific Data

Western Blot Detection of Human Caspase-1 antibody by Western Blot. View Larger

Detection of Human Caspase‑1 by Western Blot. Western blot shows lysates of A431 human epithelial carcinoma cell line and THP-1 human acute monocytic leukemia cell line. PVDF Membrane was probed with 0.25 µg/mL of Goat Anti-Human Caspase-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6215) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Caspase-1 at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Caspase‑1 in THP‑1 Human Cell Line. Caspase-1 was detected in immersion fixed THP-1 human acute monocytic leukemia cell line using Goat Anti-Human Caspase-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6215) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Detection of Human Caspase‑1 by Simple WesternTM. Simple Western lane view shows lysates of A431 human epithelial carcinoma parental cell line and Caspase-1 knockout A431 cell line (KO), loaded at 0.2 mg/mL. A specific band was detected for Caspase-1 at approximately 52 kDa (as indicated) using 25 µg/mL of Goat Anti-Human Caspase-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6215) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Western Blot Shows Human Caspase‑1 Specificity by Using Knockout Cell Line. Western blot shows lysates of A431 human epithelial carcinoma parental cell line and Caspase-1 knockout A431 cell line (KO). PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human Caspase-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6215) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Caspase-1 at approximately 50 kDa (as indicated) in the parental A431 cell line, but is not detectable in knockout A431 cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Caspase-1

Caspase-1, also known as IL-1 beta -converting enzyme (ICE), is an aspartic protease that plays a key role in the inflammatory response and apoptosis. Caspase-1 precursor (about 50kDa) can be cleaved and the active enzyme consists of a complex of two 20 kDa (aa 120-297) and two 10 kDa (aa 317-404) subunits which associate following cleavage of inactive precursors. Caspase-1 is required for proteolytic cleavage of the IL-1 beta precursor to form the active proinflammatory cytokine. Alternate splicing generates several additional Caspase-1 isoforms with deletions in the propeptide regions or also in the mature subunits. Within the large subunit, human Caspase 1 shares 61% aa sequence identity with mouse and rat Caspase-1.
