Vector Backbone Description: Backbone Marker:Markus Ralser (Addgene plasmid # 19407), Clontech = pTRE-T2; Vector Backbone:pTRE-Tight2; Vector Types:Mammalian Expression, RNAi; Bacterial Resistance:Ampicillin
Comments: In fusion cloning was used to insert a synthetic DNA template containing the mIR cassette from the pCDNA 6.2-GW/miR into the EcoRI and XbaI site of pTRE-T2-Tight. I engineered two BsaI sites into the miR cassette so users can digest the vector with BsaI for directional cloning of Blockit microRNAs using the Block-IT RNAi designer engine from Invitrogen. To make the BsaI sites unique I mutated out Bsa I sites in the original pTRE-T2 Tight vector and also removed XhoI and XbaI sites by site-directed mutagenesis from the pTRE-T2 vector and the corresponding puromycin/hygromycin resistance genes. I also dropped in a unique NheI and EagI restriction site between the ampicillin gene and the pMB101 origin of replication sequence so that the puromycin and hygromin genes could be placed into the pTRE-T2-miR vector with the infusion cloning method. Investigators can remove the miR cassette from the pTRE-T2 puromycin/hygromycin vector and using cloning methods to insert any cDNA of interest into the site for doxycline-inducible expression of the target cDNA. A single vector can be utilized from the production of tetracycline inducible miRNAs or cDNAs.
For puromycin use .25 micrograms/ml to .50 micrograms/ml to get clones after a couple of weeks. Growth response curve tested in 293HEK cells. Suggest methylation deficient cells from NEB to alleviate methylation sensitive restriction sites like Xba I. However not recommended for long-term propagation and storage.

Genotype= aspC tyrB ilvE avtA
Precursor strain = RF17
Modified from the parent Escherichia coli BL21(DE3) strain
Selective amino acid labeling (and/or requirement) = Asp, Tyr, Phe, Ile, Leu, Val####
####RF18 has knockouts in the four general transaminase genes of E. coli (aspC, tyrB, ilvE, and avtA) and is found to require the presence of L-Asp, L-Tyr, L-Phe, L-Ile, L-Leu plus L-Val for slow growth in M63 minimal medium.

Note that these strains are NOT competent cells and one needs to make them competent before use.
Supplemental documents contain a list of PCR primers used for verification of each knocked-out gene as well as an image showing PCR results for this strain.
