Pt. Daniel et al., Detection of genomic DNA fragmentation during apoptosis (DNA ladder) and the simultaneous isolation of RNA from low cell numbers, ANALYT BIOC, 266(1), 1999, pp. 110-115
In the present paper we describe a rapid and sensitive method for the simul
taneous isolation of total RNA and genomic plus low-molecular-weight DNA fr
om apoptotic cells. Using this method, we were able to detect a DNA ladder
from as low as 30,000 apoptotic cells in only 45 min including gel electrop
horesis. In addition, RNA can be readily obtained from the same specimen to
assess gene expression during apoptosis. This method therefore appears to
be advantageous when sensitivity and low amounts of sample material are a l
imiting factor. (C) 19999 Academic Press.
