I've used plasmids with two separate expression cassettes. However,
you cannot insert the two cDNAs in tandem and get expression of the
Instead, use a vector with two MCS separated by an IRES. Clone the first
cDNA into the first MCS (before the IRES), and the second cDNA into the
MCS that is after the IRES.
We got a plasmid like this from the Aiyar lab.
