Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, IF-IC=Immunofluorescence (Immunocytochemistry), F=Flow Cytometry
Specificity / Sensitivity
Cleaved Caspase-8 (Asp387) (D5B2) XP® Rabbit mAb (Mouse Specific) recognizes endogenous levels of mouse caspase-8 only when cleaved at Asp387. In addition to the p18 subunit, this antibody also detects cleavage products containing the pro-domain with the p18 subunit (p43).
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp387 of mouse caspase-8 protein.

Western blot analysis of extracts from CTLL-2 cells, untreated or treated with cycloheximide (CHX, 10 μg/ml, overnight) followed by hTNF-α #8902 (20 ng/ml, 4 hours), using Cleaved Caspase-8 (Asp387) (D5B2) XP® Rabbit mAb (Mouse Specific).
Flow cytometric analysis of CTLL-2 cells, untreated (red) or treated with cyclohexamide and hTNF-α #8902 (blue), using Cleaved Caspase-8 (Asp387) (D5B2) XP® Rabbit mAb (Mouse Specific).
Confocal immunofluorescent analysis of Raw 264.7 cells, untreated (left) or treated with TNF-α and Cycloheximide (20 ng/ml and 2.5 ug/ml, 4 hours and 3 hours; right), using Cleaved Caspase-8 (Asp387) (D5B2) XP® Rabbit mAb (Mouse Specific) (green).

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.
