Description

General description

This shRNA non-mammalian control was designed using our Turbo GFP sequence and may cause some knockdown of tGFP. For maximum knockdown of tGFP, please refer to SHC004, SHC004V, SHC004H, SHC204, or SHC204V.

Small interfering RNAs (siRNAs) expressed from short hairpin RNAs (shRNAs) are a powerful way to mediate gene specific RNA interference (RNAi) in mammalian cells. The MISSION product line is based on a viral vector-based RNAi library against annotated mouse and human genes. shRNAs that generate siRNAs intracellularly are expressed from amphotropic lentivirus viral particles, allowing screening in a wide range of mammalian cell lines. In these cell lines, MISSION shRNA clones permit rapid, cost efficient loss-of-function and genetic interaction screens.

The lentiviral transduction particles are produced from an shRNA lentiviral non-target control plasmid. It is useful as a negative control in experiments with the MISSION shRNA target sets.

Unlike murine-based MMLV or MSCV retroviral systems, lentiviral-based particles permit efficient infection and integration of the specific shRNA construct into differentiated and non-dividing cells, such as neurons and dendritic cells,¹ overcoming low transfection and integration difficulties when using these cell lines. Self-inactivating replication incompetent viral particles are produced in packaging cells (HEK293T) by co-transfection with compatible packaging plasmids.^2-3

In addition, the lentiviral transduction particles are pseudotyped with an envelope G glycoprotein from vesicular stomatitis virus (VSV-G), allowing transduction of a wide variety of mammalian cells.⁴ The lentiviral transduction particles are titered via a p24 antigen ELISA assay and pg/ml of p24 are then converted to transducing units per ml using a conversion factor. The conversion can be viewed at: www.tronolab.com.

When conducting experiments using MISSION^® shRNA clones, the proper controls should be a key element of your experimental design to allow for accurate interpretation of knockdown results. The MISSION Control Transduction Particles are a critical positive control to monitor transduction efficiency.
