Western blot analysis of extracts from HeLa, THP-1, and YB2/0 cell lines using Caspase-8 (D35G2) Rabbit mAb.
Western blot analysis of extracts from control HeLa cells (lane 1) or Caspase-8 knockout HeLa cells (lane 2) using Caspase-8 (D35G2) Rabbit mAb #4790 (upper), or β-actin (13E5) Rabbit mAb #4970 (lower). The absence of signal in the Caspase-8-knockout HeLa cells confirms specificity of the antibody for Caspase-8.
Western blot analysis of extracts from CTLL-2 cells, untreated (-) or treated with Cycloheximide #2112 (CHX, 10 μg/ml, overnight) followed by Human Tumor Necrosis Factor-α (hTNF-α) #8902 (20 ng/ml, 4 hr; +), using Caspase-8 (D35G2) Rabbit mAb.
Western blot analysis of 293T cells, mock transfected (-) or transfected with a construct expressing Myc/DDK-tagged full-length human Caspase-8 protein (hCasp8-Myc/DDK; +), full-length mouse Caspase-8 protein (mCasp8; +), or full-length human Caspase-10 protein (hCasp10; +), using Caspase-8 (D35G2) Rabbit mAb.

Protocol Id: 10
Caspase-8 (D35G2) Rabbit mAb detects endogenous levels of total caspase-8, including the p10 subunit of the activated protein. Caspase-8 (D35G2) Rabbit mAb may also cross-react with overexpressed levels of caspase-10.
Human, Mouse, Rat
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxyl terminus of human caspase-8 protein.
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.
