Anti-DNA, ss, clone 2Q2282

Apoptosis is a genetically and biochemically regulated mechanism of programmed cell death that plays an important role in a variety of human diseases including cancer, immune disorders, and neurologic, cardiovascular and infectious diseases. Decreased stability of apoptotic DNA toward thermal denaturation is induced by the proteolysis of DNA-bound proteins during the execution of apoptosis. This conclusion is supported by the binding of anti-ssDNA monoclonal antibodies to non-apoptotic cells treated with proteinase K before heating and by prevention of DNA denaturation and MAb reactivity in apoptotic nuclei reconstituted with histones (Frankfurt et al. 1996, 1997). Thus, staining of cell suspensions and tissue sections with such antibodies following a heat treatment, which induces DNA denaturation in situ only in apoptotic nuclei, is a specific and sensitive method for the detection of apoptotic cells. D3878-16 provides a cellular marker specific for apoptotic death that is independent of internecleosomal DNA fragmentation and is useful for the detection of different stages of apoptosis in various cell types.
