We transfect in vitro transcriptions via electroporation, in RNAse-free PBS.
The conditions will have to be worked out on your machine with your cells.
We have calculated that ~60% of survivors (BHK-21 cells) take up the RNA.
Also, lipofectin works well for RNA, albeit at lower efficiency than
electroporation. Again, you'll have to optimize conditions. Note, lipofectamine
was far less efficient than lipofectin for delivering RNA, although the reverse
has generally been true for DNA in our lab. Just my thoughts...
