how to remove contaminated RNA in DNA extract - (Feb/04/2008 )

I used phenol:chlorform method to extract my genomic DNA, but forgot to put RNAase along with proteinase.
After extraction, 260/230 ratio is around 0.66, 0.60 and 260/280 ratio is around 1.81 and 1.71.
Does that mean much contaminated RNA should be in the DNA extract?

Is there any method for RNA removal after DNA extraction?

looks more like phenol and/or carbohydrate contamination. your 260/280 looks good.

if it's phenol contamination you can do a chloroform extraction.

Thanks. is there a method i can remove RNA in already extracted DNA?

treat with dnase-free rnase then re-extract with phenol/chloroform.

dnase-free rnase treatment is the best i think .........
if much worried then you can go for PEG treatment
