Product Description

It is well accepted that microRNAs (miRNAs) play a key role in stem cell self-renewal, differentiation, and reprogramming 1. More recent studies have demonstrated that specific miRNAs can significantly promote reprogramming of somatic cells toward pluripotency, or substitute reprogramming transcription factors. Furthermore, it was reported that direct transfection of synthetic mature miRNAs (a combination of miR200c/miR302s/miR369s families) alone 2 allowed generation of mouse and human iPSCs without any genetic modifications. Those studies opened up the possibilities of using these synthetic mature miRNAs to enable or facilitate reprogramming experiments in different studies.

control siRNA (5 nmol)
250 µL Proprietary  

Note: 5 nmol of miRNA is enough for 400 transfections in 6-well plate under normal condition

Technical information:

Package:   Each vial contains freeze-dried synthetic RNA at indicated amount
Purity:   90-95% by HPLC
Quality Control:   Each RNA strand was validated to have correct mass
Basic Protocol:   1. Add indicated amount of RNAase-free water to make 20 µM stock solution, aliquote and store at -80oC for longer shelf life (up to 12 months), avoid repeated freeze/thaw cycles.
2. Optimize the transfection condition using Cell Death control siRNA in 24 well. Parameter needed to be optimized: transfection reagent, amount of transfection reagent, and amount of siRNA. The effect of Cell Death siRNA can be observed 48-72 hours post transfection under microscope.
3. Use the optimized conditions for miRNA experiment. Repeated transfection is needed for sustained effects over a long period of time.
