I am trying to biotinylate RNA, but I would like it to be biotinylated
at the 5' or 3' (whichever) end only. I am trying to avoid internal
labeling. Looking at synthetic sources, they discouraged me mainly because
it being too long (40 and 60 bp). I am also considering synthetizing a
small RNA oligo and ligating it to the rest but it does not seem to be
a trivial thing. Any Ideas?
Happy world cup, and may Brazil win.
