Cellular Delivery of PNA by MPOC. Next, we used
MPOCs to leak PNAs into cells to perform antigene function.
The binding site of NF-κB transcription factor is between −75
and −63 in the promoter of Il6 gene
17
and the sequence
between −74 to −63 (GGGATTTTCCCA) was selected as the
antigene target site. We synthesized two 12mer PNAs, one with
the sequence specific to the antisense strand of the binding site
of NF-κB transcription factor (PNA
) and the other with a
random sequence (PNA
random
NFκB
). Also we fluorescently labeled
the two PNAs with fluorescein (Flu): PNA
,and
PNA
.
