TransIT®-siQUEST™ Transfection Reagent

High Efficiency siRNA delivery to Mammalian Cells


  • Developed specifically for high efficiency siRNA delivery to mammalian cells
  • Unique lipopolyplex formulation offers advantages in select cell types
  • Low toxicity reagent proven to work effectively in a wide range of cell types
  • Achieve higher transfection efficiencies and save time by transfecting in the presence of serum and eliminating media changes
  • The reagents are supplied with an optimized protocol, and a ready-to-use single vial


  • TransIT®-siQUEST™ Transfection Reagent enables highly efficient siRNA transfection with significantly reduced levels of cell damage as compared to cationic-liposome based transfection reagents. Transfections are most effective when carried out in complete growth media, with no media change or serum addition required. TransIT®-siQUEST™ Reagent efficiently delivers siRNA to a wide range of cell lines, promoting high levels of target gene expression knockdown. These unique features make the TransIT®-siQUEST™ Transfection Reagent ideal for siRNA-mediated gene silencing studies.
  • The TransIT®-siQUEST™ Reagent is a complement to Mirus' popular TransIT-TKO® siRNA Transfection Reagent. Each unique formulation provides a distinct transfection profile for high efficiency, broad-spectrum siRNA delivery.

Cell Lines Successfully Transfected:

  • A549, CHO-K1, COS-7, HEK 293, HeLa, Hepa1c1c7, HepG2, MCF-7, NIH 3T3, RAW 264.7, and Vero cells.
