What are your thoughts on the relative merits of

a-	isopropanol
b-	95 % ethanol

c-	99% ethanol

when used to precipitate RNA, DNA and synthetic oligonucleotides out
of solution? I found in ine case that 95% ethanol did not substitute
efficiently for isopropanol when precipitating RNA but I did that
experiment only once.
