Product Summary for Human Caspase-1/ICE Quantikine ELISA Kit
The Quantikine Human Caspase-1 Immunoassay is a 3 hour solid phase ELISA designed to measure Caspase-1 in cell culture supernates. It contains recombinant human Caspase-1 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained measuring natural human Caspase-1 showed dose-response curves that were parallel to the standard curves obtained using the recombinant Caspase-1. These results indicate that this kit can be used to determine relative mass values for natural human Caspase-1.

Linearity
To assess the linearity of the assay, cell culture supernate samples containing and/or spiked with high concentrations of Caspase-1 were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: Caspase-1
Caspases are a family of cytosolic aspartate-specific cysteine proteases involved in the initiation and execution of apoptosis. They are expressed as latent zymogens and are activated by an autoproteolytic mechanism or by processing by other proteases (frequently other caspases). Human caspases can be subdivided into three functional groups: cytokine activation (caspase-1, -4, -5, and -13), apoptosis initiation (caspase-2, -8, -9, -and -10), and apoptosis execution (caspase-3, -6, and -7).
Caspases are regulated by a variety of stimili, including APAF1, CFLAR/FLIP, NOL3/ARC, and members of the inhibitor of apoptosis (IAP) family such as BIRC1/NAIP, BIRC2/cIAP-1, BIRC3/cIAP-2, BIRC4/XIAP, BIRC5/Survivin, and BIRC7/Livin. IAP activity is modulated by DIABLO/SMAC or PRSS25/HTRA2/Omi. Cell-permeable and irreversible peptide inhibitors are also available for different caspases.
