Markers and reporters Vectors with mCherry or eGFP reporter genes for monitoring transfection or transduction efficiencies. The most significant challenge is delivery. If the shRNA is expressed at levels that are too high, the cell might not be able to correctly process the endogenous RNA which could cause significant problems. This product is then processed by Dicer and loaded into the RNA-induced silencing complex (RISC). We do not have optimized protocols for transduction of individual cell lines, including Jurkat. Traditional short hairpin RNA (shRNA) sequences are transcribed in the nucleus from a vector containing a Pol III promoter. The features of single-strand oligonucleotide encoding shRNA sequence include the following (Fig. Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA at first non-coding RNA molecules, typically 20-24 (normally 21) base pairs in length, similar to miRNA, and operating within the RNA interference (RNAi) pathway. For each shRNA and control plasmids, to a second tube, add 4.5 . Great control, easy transduction, worked very well for our purpose. HEK293 cells are a convenient and easily transfectable system for screening all human shRNA constructs (use NIH3T3 for mouse shRNA and OLN-93 for rat shRNA constructs). We strongly recommend that a kill-curve be performed on each batch of cells to ensure that the optimal puromycin concentration is employed. Non-effective 29-mer Scrambled shRNA Cassette in pGFP-C-shLenti Vector, 5 ug. If your gene is not expressed in HEK293, you can do a co-transfection with an expression construct and the shRNA construct at a 1:1 ratio transiently into HEK293 cells. 14. However, this method is not applicable in vivo and thus has limited utility. post-transfection and add puromycin (0.5 - 1ug/ml) to the fresh growth medium. It interferes with the expression of specific genes with complementary nucleotide sequences by degrading mRNA .
