Hello, just wanted top add that it is possible to use lipofection to introduce
proteins into cells. I have used the pT7T7 system to co-transfect plasmids
containing genes driven from the T7 Pr and T7 RNA Polymerase. Cells used were
L929 (rather tranfectable), and best results (%trfxn efficiency) were obtained
with lipofectamine. T7RNAP is ~98kDa, and Ab's range from 150kDa to
>900kDa., for what it's worth. Also, you might consider the net charge on
these proteins
for their ability to form transfection complexes. Maybe the T7 is being brought
in courtesy of the plasmid, which acts as a carrier. Finally, do the experiment,
it's the only way to know! ps let us know how it works.
