Fig. 5. Relative expression of `liver' and `gill' mRNA/cDNA in tissues of gulf
toadfish Opsanus beta. Representative agarose gel of a restriction
digest experiment of mRNAs obtained after RT-PCR with primer pair GS 501 and
301. Lanes 1 and 14 are molecular mass markers, lanes 25, gill; lanes
69, liver; lanes 1013, stomach. From left to right, for each
tissue: uncut PCR products, PCR products digested with StuI, PCR
products digested with PvuII, and PCR products digested with
StuI plus PvuII.
