Product Usage Information

Application Dilution
Flow Cytometry (Fixed/Permeabilized) 1:50

Storage

Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibodies. Protect from light. Do not freeze.

Specificity/Sensitivity

Cleaved Caspase-8 (Asp374) (18C8) Rabbit mAb (PE Conjugate) recognizes human caspase-8 when cleaved at Asp374 (isoform B, Asp391 on isoform A). This antibody detects 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 Asp374 of human caspase-8 protein.

Description

This Cell Signaling Technology antibody is conjugated to phycoerythrin (PE) and tested in-house for direct flow cytometry analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated Cleaved Caspase-8 (Asp374) (18C8) Rabbit mAb #9496.

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.

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).
