Simplicon Reprogramming RNA (OKSG)

Various methods utilizing viruses, DNA, RNA, miRNA and protein have been developed to generate integration-free induced pluripotent stem cells (iPSCs). Disadvantages to existing methods include: (1) low reprogramming efficiency (i.e. DNA and protein), (2) a lengthy requirement for negative selection and subcloing steps to remove persistent traces of the virus (i.e. Sendai virus)1 and (3) for daily transfections of four individual in vitro generated mRNAs over a 14 day period (i.e. mRNA based)2.

EMD Millipore′s Simplicon RNA Reprogramming Kit (OKSG) is a safe and efficient method to generate integration free, virus-free human iPS cell using a single transfection step. The technology is based upon a positive strand, single-stranded RNA species derived from non-infectious (non-packaging), self-replicating Venezuelian equine encephalitis (VEE) virus3. The Simplicon RNA replicon is a synthetic in vitro transcribed RNA expressing all four reprogramming factors (OKS-iG; Oct4, Klf4, Sox2 and Glis1) in a polycistronic transcript that is able to self-replicate for a limited number of cell divisions.

Advantages of the TM=["SIMPLICON"] RNA Reprogramming Kit:

• Integration-free, footprint-free iPS cells. No risk of genomic integration

• Safe, virus free, synthetic polycistronic RNA replicon (all four reprogramming factors in 1 RNA strand)

• Only 1-day transfection required. The RNA replicon is able to self-replicate, elliminating the need for laborious daily transfection of multiple individual mRNAs over a 14 day period.

• Efficient and rapid reprogramming.

• No screening required to ensure viral remnants are not present.

• Controlled elimination of synthetic RNA replicon by removal of B18R protein.

• Validated for reprogramming in feeder-based and feeder-free culture conditions.

1. VEE-OKS-iG RNA: (Part No. CS210583) One (1) vial containing 10 µL of RNA (1 ug/uL). Store at -80°C. 2. B18R-E3L RNA: (Part No. CS224516) One (1) vial containing 10 µL of RNA (1 µg/µL). Store at -80°C.

Tested to confirm the generation of iPS cells from p6 human foreskin fibroblasts. Other cell types have not been tested and thus similar results can not be guaranteed.

VEE-OKS-iG and B18R RNAs: Stable for 4 months from date of receipt when stored appropriately at -80°C. For best recovery, quick-spin the vial prior to opening. Thaw on ice. While on ice, aliquot into sterile, nuclease-free Eppendorf^® tubes and store at -80°C. Limit repeated freeze-thaw cycles. Use in a sterile RNAse-free environment.
