Fig. 3. Stability of R70pRomiLuc in Atlantic cod blood after intravenous
administration (A) and in vitro in whole blood (B). Supercoiled (SC)
and open circular (OC) topoform were reduced to linear (L) topoform and
degradation products, both in vitro and in vivo. M,
molecular marker 1 kb plus (Invitrogen); N, negative control (blood without
R70pRomiLuc); S, standard (R70pRomiLuc). The negative control demonstrates
that there is no detectable endogenous pDNA in the blood.
