Greetings, recently I have acquired the pCDH-CMV-MCS-EF1-CopGFP-T2A-Puro vector (V012884). I would like to know whether the gene of interest's expression is regulated by the CMV promoter or not, given that this vector contains two sets of 5'LTRs. Specifically, I would like to know which set is integrated into the cell genome subsequent to transduction. Regards in advance,
