Immunofluorescent analysis of Caspase 8 (green) HEK293T cells. Cells fixed with 4% formaldehyde were permeabilized and blocked with 1X PBS containing 5% BSA and 0.3% Triton X-100 for 1 hour at room temperature. Cells were probed with a Caspase 8 polyclonal antibody (Product # PA1-29159) at a dilution of 1:100 overnight at 4°C in 1X PBS containing 1% BSA and 0.3% Triton X-100, washed with 1X PBS, and incubated with fluorophore-conjugated goat-anti-rabbit IgG secondary antibody at a dilution of 1:200 for 1 hour at room temperature. Nuclei (blue) were stained with DAPI. Images were taken on a Leica DM1000 microscope at 40X magnification. Data courtesy of the Innovators Program.

PA1-29159 detects Caspase 8 from human, mouse, rat samples.
PA1-29159 has been successfully used in IF/ICC, immunohistochemistry (paraffin tissue), immunoprecipitation, and Western blot applications.
The PA1-29159 immunogen corresponds to amino acids 217-350 mapping within the caspase-8 p18 subunit of human origin.
Caspase 8 binds to the death effector domain (DED) of FADD through an analogous DED domain present in tandem in the proform of the Caspase 8 protein. Recruitment of Caspase 8 to the Fas receptor results in oligomerization of the Caspase 8 protein, which in turn drives up its autoactivation through "self-cleavage". Activated Caspase 8 then activates other downstream caspases including Caspase 9, thereby commiting the cell to undergo apoptosis. Reacts with Jurkat cells and Tonsil.
