DFF40; RB X-100UG

Application

Western blot: 1:500-1:1,000

K562 or Jurkat whole cell lysate can be used as a positive control and a 40 kDa band should be detected.

Optimal working dilutions must be determined by end user.

Detect DFF40 using this Anti-DFF40 Antibody validated for use in WB.

Immunogen

A peptide corresponding to amino acids 147-164 of mouse CAD (Enari et al. 1998). The sequence differs from human DFF40 by two amino acids (Halenbeck et al. 1998; Liu et al. 1998).

Specificity

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 deoxyribonuclease) (Enari et al. 1998; Sakahira et al. 1998). The human homologue of mouse CAD was more recently identified by three groups independently and termed CPAN and DFF40 and human CAD, respectively (Halenbeck et al. 1998; Liu et al. 1998; Mukae et al. 1998). DFF45/ICAD is the inhibitory protein of DFF40/CAD (Enari et al. 1998; Sakahira et al. 1998; Liu et al. 1997) and forms complex with DFF40/CAD. Upon cleavage of DFF45/ICAD by activated caspase, DFF40/CAD is released and activated and eventually cuases the degradation of DNA in the nuclei. Activation of DFF40/CAD, which causes DNA degradation, is the hallmark of apoptotic cell death.
