Depositor Comments

pUltra was cloned by Yildirim Dogan (). It is described in the associated article (PMID 22427958) and also in PMID 24630793.

This is a 3rd generation Lentiviral vector with an internal Ubiquitinc Promoter.

By cloning into the compatible cloning sites* (XbaI and BamHI) downstream of EGFP-P2A, you get a bi-cistronic expression of EGFP and the gene of interest. You can clone a second gene of interest into the NheI/bclI**donwstream of EGFP-P2A-gene1-T2A and get a multi-cistronic expression of all three genes.

* compatible cloning site (ccs): you can pcr amplifiy your gene of interest with a forward primer including one of these cutting sites: SpeI or NheI or XbaI and a reverse primer with one these cutting sites: BglII or BamHI or bclI. The PCR product is now compatible with the first site as well the 2nd site. "You can mix and match".

** for bclI the vector has to be amplified by dam-methylation defective E coli strains (e.g. SC110 Stratagene).

Further advantage of the vector is, that you can simultaneously do RNAi by cloning H1-shRNA cassettes into the unique SnaBI site in the 3´-LTR. Plus while integration the RNAi cassette gets doubled, since the 5´LTR is dublicated while reverse transcripton from the 3´-LTR
