DNA fragmentation factor, 40kDa, beta polypeptide (caspase-activated DNase)
Apoptosis is related to many diseases and induced by a family of cell death receptors and their ligands. Cell death signals are transduced by death domain containing adapter molecules and members of the caspase family of proteases. These death signals finally cause the degradation of chromosomal DNA by activated DNase. A mouse DNase that causes DNA fragmentation was identified recently and designated CAD (for caspase activated deoxyribo-nuclease) (1,2). The human homologue of mouse CAD was more recently identified by two groups independently and termed CPAN and DFF40 (3,4). Human DFF45 (Cat. # IMG-114 & 115) and its mouse homologue ICAD are the inhibitors of CPAN/DFF40 and CAD, respectively (5). Upon cleavage of DFF45/ICAD by activated caspases, DFF40/CAD is released and activated and eventually causes degradation of DNA in the nuclei1 (4). Activation of CAD/DFF40, which causes DNA degradation, is the hallmark of apoptotic cell death.

FAQs for DFF40/CAD Antibody (NB120-13592). (Showing 1 - 1 of 1 FAQs).
Does Novus offer any CAD (caspase activated DNase) antibodies that specifically look at the activation state of CAD? And if so, how well does this antibody work with chicken?
CAD/DFF40/DFFB is inhibited by being bound by DFFA. Because of this manner of inhibition, antibodies will not be able to recognize the difference between activated and inhibited DFFB, so we do not have a product specifically for activated or inhibited DFFB and this product will probably be nearly impossible to make. Unfortunately, the human and chicken sequence appear to be divergent for any of our immunogens to recommend any antibody to test for cross-reactivity with chicken. I apologize for the inconvenience.
