Resource Information

Depositor Comments

CMV promoter is upstream of the bicistronic coding cassette with SV40-Large T and HSV1-TK. During reverse transcription U3 region of the 3'LTR, with LoxP, is duplicated; LoxP sites end up flanking the genome of the integrated provirus. Upon expression of Cre, provirus is excised.

Please note that the full sequence for this plasmid is approximated and not fully verified--there will be discrepancies between Addgene's quality control sequence and the theoretical sequence from the depositor. Please visit the Trono lab for cloning strategies, protocols, publications, and more. See LentiWeb for discussion on cloning strategies and protocols.
