We routinely make synthetic RNA for injection into cells, RNAase
protection assays and whole mount in situ digoxigenin probes. None of the
kits work as well as when we assemble the reactions ourselves. In fact,
we had to abandon using Promega's Ribomax kit for RNA injection into
embryos because we were getting non-specific effects due to insufficient
