Caspase-1 Antibody Summary

A synthetic peptide from the second quarter of human Caspase 1 protein.
Nuclear, Cell Membrane
This reacts with the 45 kDa protein Caspase 1 and is expressed as a proenzyme in many tissues. Active Caspase 1 is a tetramer of two subunits p10 and p20 in 2:2 ratio. Overexpression of caspase 1 can induce apoptosis in fibroblast, which can be inhibited by overexpression of Crm A, a protein from pox virus.

  • Western Blot 1:100-1:2000
  • Immunohistochemistry 1:10-1:500
  • Immunohistochemistry-Frozen 1:10-1:500
  • Immunohistochemistry-Paraffin 1:10-1:500
Application Notes
IHC: This antibody may be diluted to a titer of 1:25-1:50 in an ABC method. We suggest an incubation period of 30 minutes at room temperature. However, depending upon the fixation conditions and the staining system employed, optimal incubation conditions and antibody dilutions should be determined by the user. Formalin fixed paraffin embedded tissue sections require high temperature antigen unmasking with all10 mM citrate buffer, pH 6.0 prior to immunostaining.

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 a2b2 tetramer to form the active enzyme. Caspase 1 is similar to the cell death gene CED3 of C. elegans and regulates multiple proinflammatory cytokines, including Interleukin 1b and interferon-gamma-inducing factor. Caspase 1 plays a role down stream of Caspase 8 which is involved in Fas-mediated apoptosis.
