TransIT®-TKO: Small Interfering RNA (siRNA) Transfection Reagent

For High-Efficient Small Interfering RNA Transfection

Knock out of firefly luciferase expression in 3T3-luc cells using TransIT®-TKO

3T3-luc, a cell line stably expressing the firefly luciferase gene, was used to test the ability of TransIT®-TKO reagent/siRNA complexes to knock out expression of an existing target gene.


  • Delivers siRNA targeted against both transient transfected and stable genes in a variety of cell lines while not effecting untargeted expression of similar genes - significantly reduced cell damage
  • Ideal for all siRNA-mediated gene silencing studies
  • No media change or serum addition required


  • The TransIT®-TKO 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 without a media change or serum addition.
  • When complexed with even low levels of siRNA, TransIT®-TKO reagent successfully knocks out target gene expression in a variety of cell lines. Transgene expression can be silenced either when the siRNA is transfected before, concurrently or after the transfection of the expression vector. These unique features make TransIT®-TKO transfection reagent ideal for all siRNA-mediated gene-silencing studies. It is the only transfection reagent designed to efficiently deliver small interfering RNA to cells in vitro.
  • TransIT®-TKO reagent, combined with the correct siRNA sequence against the target mRNA, can silence endogenous, stable or transient gene expression.
