The substance you mean is probably CTAB,
Cetyltrimethylammoniumbromide. It is avaiable from
Sigma, it is a white solid and AFAIK not too
We use it for DNA plasmid minipreps, so
I do not have present experience for RNA
extracting, but you may look at following
older refs, where a RNA extracting method
with CTAB is described.
Bellamy et al 1968 Methods in Enzymology, S. 156-160.
Scheller, Karlson 1977 J. Insect Physiol 23 S. 435-440
I used them during my diploma thesis and remember
them as quite tedious.
Hope that helps anyway.
