| Specificity / Sensitivity | Cleaved Caspase-8 (Asp391) (18C8) Rabbit mAb detects human Caspase-8 when cleaved at Asp391 (isoform A, Asp374 on isoform B). This antibody will detect cleavage products containing the pro-domain with the p18 subunit as well as the p18 subunit alone. |
| Source / Purification | Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues adjacent to Asp391 of human Caspase-8. Western Blotting
Western blot analysis of HeLa cells transfected with the death receptors Fas and DR5, or treated with cycloheximide (CHX) and TNF-alpha using Cleaved Caspase-8 (Asp391) (18C8) Rabbit mAb (upper), or total Caspase-8 (1C12) Mouse mAb (lower). IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human colon (chronic inflammation) using Cleaved Caspase-8 (Asp391) (18C8) Rabbit mAb. IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded HeLa cells, untreated (left) or Cycloheximide and TNFα-treated (right), using Cleaved Caspase-8 (Asp391) (18C8) Rabbit mAb. IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human Non-Hodgkin's lymphoma using Cleaved Caspase-8 (Asp391) (18C8) Rabbit mAb. Flow Cytometry
Flow cytometric analysis of Jurkat cells, untreated (blue) or etoposide-treated (green), using Cleaved Caspase-8 (Asp391) (18C8) Rabbit mAb compared to a nonspecific negative control antibody (red). IF-IC
Immunofluorescent staining of HeLa cells untreated or treated with cytotoxic anti-Fas Antibody, using Cleaved Caspase-8 (Asp391) (18C8) Rabbit mAb. |
| Background | Apoptosis induced through the CD95 receptor (Fas/APO-1) and tumor necrosis factor receptor 1 (TNFR1) activates caspase-8 and leads to the release of the caspase-8 active fragments, p18 and p10 (1-3). Activated caspase-8 cleaves and activates downstream effector caspases such as caspase-1, -3, -6, and -7. Caspase-3 ultimately elicits the morphological hallmarks of apoptosis, including DNA fragmentation and cell shrinkage. |
