  • Background Information
    Caspase-4 (also know as Ich-4, ICErelII, TX) is a member of the caspase-family of cysteine proteases. Similar to other caspases, caspase-4 exists in cells as an inactive proenzyme which is matured by proteolysis to yield large and small subunits. The active caspase-4 is a heterotetramer consisting of two large and two small subunits. To date the mechanism of caspase-4 activation and roles of caspase-4 in apoptosis are poorly understood. The recombinant active human caspase-4 was expressed in E. coli. The active caspase-4 is routinely tested at BioVision for its ability to enzymatically cleave these two substrates Ac-WEHD-pNA (Cat. #1102-200) or Ac-WEHD-AFC (1101-200).
  • Handling
    Centrifuge the vial prior to opening.
  • Usage
    For Research Use Only! Not to be used in humans
  • Additional description
    Human and some mouse caspases are active in apoptosis and cell death and even in necrosis and inflammation. CASP Gene and orthologous enzymes have been identifies successfully in the signal transduction cascade and pathways.
  • Properties
    Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
