Product overview
The Apoptosis and DNA Damage (H2A.X(S139) + cleaved PARP1 + Anti-GAPDH) Western Blot Cocktail (ab131385) is designed to study the induction of DNA damage and/or apoptosis in response to various stimuli. The two main components of this cocktail are monoclonal antibodies specific to cleaved-PARP1 and H2A.X phospho Ser139. H2A.X is a histone H2A family member that is phosphorylated and recruited to sites of double-strand DNA breaks. Poly [ADP-ribose] polymerase 1 (PARP1) is a DNA repair enzyme that is cleaved by activated caspases. Combined, these antibodies provide biomarkers of dsDNA breaks (H2A.X phospho Ser139) and apoptosis (cleaved-PARP1). An anti-GAPDH antibody is included as a loading control. These three readouts are easily resolved by western blot given their different molecular weights.

Cellular localization
Cleaved PARP1: Nucleus. Nucleus, nucleolus. Localizes at sites of DNA damage. Histone H2A.X: Nucleus. Chromosome. GAPDH: Cytoplasm > cytosol. Nucleus. Cytoplasm > perinuclear region. Membrane. Translocates to the nucleus following S-nitrosylation and interaction with SIAH1, which contains a nuclear localization signal (By similarity). Postnuclear and Perinuclear regions. -
