E.coli-derived recombinant human Caspase-1 (aa120-297).
Caspase-1, also known as IL-1b-converting enzyme (ICE), is an aspartic protease that plays a key role in the inflammatory response and apoptosis. The active enzyme consists of a complex of two 20kD (aa120-297) and two 10kD (aa317-404) subunits which associate following cleavage of inactive precursors. Caspase-1 is required for proteolytic cleavage of the IL-1b 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. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilutions: Western Blot: 0.25ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile PBS, 0.02% sodium azide. Aliquot to avoid repeated freezing and thawing. Store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
