I was wondering why most plant DNA extraction protocols exclude the use of
phenol - ie so far, most of the methods I've used jump right into choloroform-
isoamyl alcohol extraction after the leaf tissue is ground in CTAB buffer. Is
phenol too harsh a reagent that it could lower the yield of hi-mwt DNA?
I am a little worried about the possibility of DNAse activity going unchecked
when I use a regular, phenol-free extraction protocol for Arabidopsis leaf
tissue. Using phenol might save me the grief. What do you think?
