Description_x000D_ General description_x000D_ The MISSION pLKO.1-puro Non-Target shRNA Control Plasmid DNA is a lentivirus plasmid vector. The vector contains an shRNA insert that does not target any known genes from any species, making it useful as a negative control in experiments using the MISSION shRNA library clones. This allows one to examine the effect of transfection of a short-hairpin on gene expression and interpret the knockdown effect seen with shRNA clones. Ampicillin and puromycin antibiotic resistance genes provide selection in bacterial or mammalian cells respectively. In addition, self-inactivating replication incompetent viral particles can be produced in packaging cells (HEK293T) by co-transfection with compatible packaging plasmids. The Non-Target shRNA Control Plasmid DNA is provided as 10 μg of plasmid DNA in Tris-EDTA (TE) buffer at a concentration of 500 ng/μl._x000D_ Application_x000D_ MISSION® pLKO.1-puro non-target shRNA control plasmid DNA has been used as a control during transduction:_x000D_ • in tumor cells for multicolour imaging_x000D_ • in human adult low calcium temperature keratinocytes_x000D_ • in mouse embryonic fibroblasts, to study the biological functions of IP6K1 (inositol hexakisphosphate kinase)_x000D_ • to study the function of Zac1 (zinc finger protein regulating apoptosis and cell cycle arrest) expression in astroglial differentiation_x000D_ Legal Information_x000D_ Use of this product is subject to one or more license agreements.
