Caspases are a family of cysteine proteases that are key mediators of programmed cell death or apoptosis. The precursor form of all caspases is composed of a prodomain, and large and small catalytic subunits. The active forms of caspases are generated by several stimuli including ligand-receptor interactions, growth factor deprivation and inhibitors of cellular functions. All known caspases require cleavage adjacent to aspartates to liberate one large and one small subunit, which associate into tetramer to form the active enzyme. Caspase-1/ICE (IL-1b converting enzyme) is similar to the cell death gene CED-3 of Caenorhabditilis elegans and regulates multiple proinflammatory cytokines, including interleukin-1b and interferon-gamma-inducing factor.

FAQs for Caspase-1 Antibody (NB100-56565). (Showing 1 - 2 of 2 FAQs).

  1. We have purchased "NB100-56565 Caspase-1 Antibody (14F468)" for our experiments. It is mentioned in product data sheet that it can detect the cleave forms of Caspase-1 as well. Can you kindly tell me the expected size of cleaved subforms on WB, so that I could be sure about my results.
    • The antibody will recognize full-length Caspase-1 and cleaved caspase-1 forms that retain amino acids 371-390 of the Caspase-1 protein. In short this antibody can recognize any protein species, after processed by protease in vivo, that contains the region of a.a. 371 - 390.
  2. We are interested in your items, NB100-56565 and NB100-56564 and I would like to use them for recognizing the cleaved form of caspase 1. Would you please let me know if NB100-56565 and NB100-56564 recognize the caspase-1 p10 or p20 ? If so, could you please provide me any supporting data of them?
    • For NB100-56565 & NB100-56564 it will recognize the full length form and the p10 as the immunogen. A synthetic peptide corresponding to amino acids 371-390 RKVRFSFEQPDGRAQMPTTE of human caspase-1 was used as immunogen. The p10 subunit is aa 307-404. If you need an antibody to the p20 subunit: This will bind to the the region around aa 132. The p20 subunit is aa 120-297.
