| Hey Bommel!, I have removed DNA contaminants from RNA isolations. The bead bound DNAseI is probably more expensive than the regular DNA, plus it may be contaminated with RNases (is it RNase-free?) We usually use RNAse-free DnaseI - very very cheap, and very effective... it is easy to get rid of also - just heat your sample at 80C... thats it Rnase free Dnase is from: Qiagen http://www1.qiagen.com/Products/Acce...DNaseSet.aspx? and the one we use Promega RQ1 http://www.promega.com/tbs/9pim610/9pim610.html |
