A new study in Nature identifies a long-sought cytoplasmic 'sensor' that is responsible, at least in part, for interferon responses induced by double-stranded DNA. How do cells detect non-self ...

Over the past decade, there have been scattered reports of mammalian cells’ own DNA being found in the cytoplasm, mainly in the context of disease and aging. While it is not unusual to find DNA from ...

Since the cytoplasmic fraction has been demonstrated to be devoid of all traces of genomic DNA, this kit can isolate RNA for subsequent processes where DNA contamination must be avoided.
