Depositor Comments

A synthetic DNA containing the IRES element was cloned into EcoRI/Xba I site of pTRE-T2-miR-HYGRO vector after removal of the mIR cassette. First digest parental pTRE-T2-miR-HYGRO vector with EcoRI and Xba I to remove the miR cassette. Then the IRES cassette was ligated back to the EcoRI site and Xba I site. The IRES cassette contains the unique EcoRI site followed by unique NotI and Mlu I sites that is followed by the start of the IRES sequence. This cloning site will allow insertion of the 1st cDNA. On the 3’ end of IRES there are unique Spe I and Xba I cloning sites for insertion of the second cDNA into the cassette.

Please note- to use the BsaI and XbaI sites for cloning, you must use unmethylated DNA. You will need to isolate the DNA from a methylation deficient bacterial strain.
