Hi
I'm trying to get rid of residual DNA in my plant mitochondrial
RNA preps. I have tried a combination of precipitation in 2 M
LiCl up to 3 times, followed by a DNAse treatment. DNA fragments
of up to 800 bp in length can be amplified using PCR following
this treatment (fragments are known to be of DNA origin as they
are not edited.
I would greatly appreciate any suggestions!
