Description: The GeneClip U1 Hairpin Cloning Systems consist of linearized<br />
plasmids designed for fast and easy cloning of human target sequences to<br />
express short hairpin RNAs (shRNAs) in human cells. After transfection into<br />
human cells, in vivo expression of short interfering RNAs (siRNAs) can be<br />
effectively achieved from DNA constructs that contain a U1 RNA polymerase<br />
promoter and a siRNA template. The U1 promoter has been used successfully<br />
to generate hairpin siRNAs in vivo.<br />
To insert hairpin siRNAs into the pGeneClip Vectors, two short DNA<br />
oligonucleotides are annealed to form a DNA insert that contains the hairpin<br />
siRNA target sequence. After annealing, the oligonucleotides form overhangs<br />
that are compatible with the pGeneClip Vector ends and facilitate sticky-end<br />
ligation. Once transfected, RNA polymerase II transcribes the hairpin insert<br />
sequences to generate hairpin siRNAs in vivo.<br />
Features:<br />
• More Vector Choices: These systems provide vectors containing a<br />
variety of eukaryotic antibiotic-selectable markers for stable transfection or<br />
hMGFP for determination of transfection efficiency.<br />
• Time Savings: Vectors are supplied predigested to eliminate time-<br />
consuming vector preparation.<br />
• Convenience: Each system includes T4 DNA Ligase, 2X Rapid Ligation<br />
Buffer, Oligo Annealing Buffer and the pGeneClip Vector.<br />
• Easier Identification of Desired Clones: A PstI digestion quickly<br />
identifies positive recombinants.<br />
Storage Conditions: Store at –20°C.<br />

T7 RiboMAX Express RNAi System<br />
Product Size Cat.# Price ($)<br />
T7 RiboMAX Express RNAi System 50 × 20µl reactions P1700 738.00<br />
For Research Use Only. Not for Use in Diagnostic Procedures.<br />
Description: The T7 RiboMAX Express RNAi System is an in vitro<br />
transcription system designed for quickly producing milligram amounts of<br />
double-stranded RNA (dsRNA). The dsRNA is free of protein and other<br />
contaminants and is suitable for use in RNA interference (RNAi) in both<br />
mammalian and nonmammalian systems.<br />
The T7 RiboMAX Express RNAi System can be used to synthesize short<br />
interfering RNAs (siRNAs) of 21bp for use in mammalian systems. siRNAs<br />
synthesized in vitro have been demonstrated to be as effective as chemically<br />
synthesized siRNAs for inducing RNAi in mammalian cells.<br />
In addition, the T7 RiboMAX Express RNAi System can be used for the<br />
synthesis of dsRNA molecules of 200bp or greater, for use in nonmammalian<br />
systems. Two complementary RNA strands are synthesized from DNA template<br />
and annealed after the transcription reaction to form dsRNA. Any remaining<br />
single-stranded RNA and DNA template are removed with a nuclease<br />
digestion step. The dsRNA is then purified by isopropanol precipitation and can<br />
be introduced into the organism of choice for RNAi applications.<br />
Features:<br />
• Save Time: The T7 RiboMAX Express RNAi System produces milligram<br />
amounts of RNA in as little as 30 minutes.<br />
• Minimize Pipetting Errors: The four rNTPs and 2X transcription buffer<br />
have been combined, thus minimizing pipetting errors and setup time.<br />
Storage Conditions: Store all components at –20°C, except RNase A, which<br />
should be stored at 22–25°C after the initial thaw.<br />

Comparison of RNA interference induced by siRNAs synthesized<br />
chemically and by in vitro transcription. Two different target luciferase<br />
sequences were synthesized by in vitro transcription using the T7 RiboMAX<br />
Express RNAi System (IVT #1 and #2) and synthesized chemically (Syn #1<br />
and #2). After transfection using CodeBreaker Transfection Reagent, these<br />
siRNAs were evaluated for RNA interference in CHO cells stably expressing<br />
luciferase.<br />
