一般說明
Caspase-8 is a member of the interleukin-1β converting enzyme (ICE) family of cysteine proteases. As with other caspases, caspase-8 also exists in cells as an inactive proenzyme. During apoptosis procaspase-8 is processed at aspartate residues by self-proteolysis and/or cleavage by another caspase. The processed form of caspase-8 consists of large and small subunits which associate to form the active enzyme. The active caspase-8 has been shown to be involved in the proteolysis of poly (ADP-ribose) polymerase (PARP), an enzyme that is involved in DNA repair and genomic maintenance.
The active recombinant human caspase-8 was expressed in E. coli. The expressed caspase-8 spontaneously undergoes autoprocessing to yield the subunits characteristic of the active enzyme. The recombinant caspase-8 preferentially cleaves the substrates consisting of consensus sequence IETD (e.g., IETD-AFC and IETD-pNA). The recombinant enzyme can also be used as a positive control in caspase assays or in determining the specificty of caspase substrates.Recommended usage: 0.5-1 unit for fluorometric caspase assays and 2-4 units for colorimetric caspase assays. Optimal working dilutions must be determined by end user.

In a previous study, we demonstrated anti-vimentin antibodies in sera of patients with interstitial pneumonia. We hypothesized that antibodies in sera might detect vimentin fragments formed during the process of apoptosis. To prove this, recombinant human vimentin was digested by
