Further information: This datasheet is representative for all the MISSION TRC1/1.5 shRNA clones developed at the Broad Institute of MIT and Harvard (USA), purchased from Sigma-Aldrich (Germany) and available at BCCM/GeneCorner. Consequently, the accession number '7210' of this template clone is fictitious.
pLKO.1-puro-shRNA is a lentiviral plasmid derived from pLKO.1-puro (= SHC001 (empty vector)) by cloning a short hairpin RNA (shRNA) sequence into the AgeI and EcoRI sites.
For all TRC1.5 clones and for most but not all TRC1 clones, the EcoRI site was restored during ligation.
The shRNA insert is expressed under control of the human U6 promoter and targets a human or a mouse gene.
The data related to a specific shRNA insert is online accessible via
Search Your Favorite Gene to locate shRNAs that target your gene. Look for the validated symbol on the shRNA clones detail pages to identify functionally validated shRNAs.
For each target gene, a set of minimum 3 to 5 shRNA clones is available, providing varying levels of knockdown and targeting different regions of mRNA transcript. Sigma-Aldrich guarantees that at least one of the clones of such a set should yield more than 70% knockdown.
For a given RefSeq, there is often a shRNA clone targeting the 3' UTR, which is useful in phenotypic rescue studies using cDNA expression constructs.

Grow for 20-22 hours in TB-8gly medium (modified Terrific Broth medium, containing 8 ml/l glycerol instead of 4 ml/l) with 100 μg/ml carbenicillin, resulting in an increased plasmid stability as compared to ampicillin.
BCCM/GeneCorner uses the 'Terrific Broth, modified' from Sigma (cat. nr. T0918, Fluka). You can also prepare the medium yourself:
1. add the following to 800 ml distilled H2O:
- 12,0 g tryptone (enzymatic casein digest)
- 24,0 g yeast extract
- 8 ml glycerol
2. adjust to 900 ml with distilled H2O
3. sterilize by autoclaving (20 minutes at 121°C)
4. allow to cool to room temperature
5. adjust volume to 1000 ml with 100 ml of a filter-sterilized solution of 0,17M KH2PO4 and 0,72M K2HPO4


DH5αT1R is a T1 bacteriophage resistant DH5α derivative. Sigma sells the identical host strain (i.e. identical genotype) as GC5 (catalogue number: G3169).

The presence of a G nucleotide at the end of the nucleotide sequence of the shRNA insert on the Your Favorite Gene ( website indicates the EcoRI site has been restored.
In the compiled nucleotide sequence of this template shRNA plasmid, the shRNA sequence is replaced by a 57 bp stretch 'CCGGNNNNNNNNNNNNNNNNNNNNNCTCGAGNNNNNNNNNNNNNNNNNNNNNTTTTT', consisting of a 21 base stem and a 6 base loop.
The shRNA insert of each clone was confirmed by sequence analysis at the Broad Institute of MIT and Harvard.
