To all, I'm trying out a new RNA extraction buffer that contains Tris
(0.2M), sodium perchlorate (8M)(pH 8.3) and SDS (2%), but the SDS comes
out of solution and I can't seem to resolubilize it. I know this can
happen with other buffers, and usually mild heat will do the trick, but
it doessn't work. Any ideas?
