Invitrogen™ pSCREEN-iT™/lacZ-DEST Gateway™ Vector Kit
On demandInvitrogen™ pSCREEN-iT™/lacZ-DEST Gateway™ Vector Kit
The BLOCK-iT™ RNAi Target Screening system method uses a β-galactosidase activity assay to measure the knockdown ability of an RNAi reagent (Stealth RNAi™ siRNA, siRNA, dicer pools, or shRNA-containing plasmid). To identify the most effective knockdown reagent for your target, simply clone your target gene into the pSCREEN-iT™ /lacZ-DEST Gateway® vector. Co-transfect the resulting construct with the knockdown reagent being tested. Expressed genes will be fused to β-galactosidase, enabling you to use β-galactosidase levels to measure the amount of RNAi-induced degradation of the target gene (Figure 1). The more effective any specific knockdown reagent is at mediating RNAi, the more degradation of the fusion mRNA will occur, lowering β-gal activity
Features
- Assess the potency of any RNAi knockdown reagent using a fast, sensitive, and cost-effective β-gal reporter assay
- Identify the best knockdown reagent for your RNAi experiments without knowing protein function, western blotting, or qRT-PCR
