Specifications

Synthetic peptide (GGPRGPGELAKYGLP) corresponding to amino acids 55 to 70 of human EndoG (5).
Catalog #E2291-40P
The fragmentation of nuclear DNA is a hallmark of apoptotic cell death. The activities of caspase and nuclease are involved in the DNA fragmentation. Caspase-activated deoxyribonuclease (CAD), also termed DNA fragmentation factor (DFF40), is one such nuclease, and is capable of inducing DNA fragmentation and chromatin condensation after cleavage by caspase-3 of its inhibitor ICAD/DFF45. Caspase and CAD independent DNA fragmentation also exists. Recent studies demonstrated that another nuclease, endonuclease G (endoG), is speci cally activated by apoptotic stimuli and is able to induce nucleosomal fragmentation of DNA independently of caspase and DFF/CAD (1,2). EndoG is a mitochondrion-speci c nuclease that translocates to the nucleus and cleaves chromatin DNA during apoptosis. The homologue of mammalian EndoG is the rst mitochondrial protein identi ed to be involved in apoptosis in C. elegans (2). EndooG also cleaves DNA in vitro (4).
Applications Suitable for use in ELISA and Western Blot. Other applications not tested.
Storage and Stability Lyophilized powder may be stored at -20°C. Reconstitute to nominal volume by adding sterile 25% glycerol and store at -20°C. May be stored at 4°C for short-term only. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
