Streamline your studies and maximize your options for miR expression
Whether you’re using miRNAs to study cellular processes or develop the next generation of therapeutics, SBI’s comprehensive collection of mouse precursor miRNA lentivectors are a superior alternative to synthetic RNAs. Like synthetic miRs, SBI’s precursor miRNAs can be transfected into target cells for transient miR expression. But unlike synthetic miRs, they can also be transduced into a variety of target cells—including primary cells, stem cells, and other hard-to-transfect cell lines—to create stable miR-producing cell lines, maximizing your options for miR expression.
Why else choose SBI’s precursor miRNA lentivectors?
In addition, SBI’s precursor miRNA lentivectors are designed for efficient expression and accurate processing into mature miRNAs, for native miR-like behavior. Each construct is cloned with the native stem-loop structure plus an additional 200 – 400 bps of upstream and downstream DNA, ensuring that the miRNA processing machinery operates just as it would with the native transcript.
And because our collection includes cancer and stem cell-related miRNA clusters, we offer a wider range of constructs than just the mature miRNA sequences listed in miRbase.
The precursor miRNA Expression Lentivectors drive expression of the miR precursor with the constitutive CMV promoter, for strong expression in common cell types including HeLa, HEK293, and HT1080 cell lines. Transductants/transfectants can be easily selected for or sorted using copGFP and puromycin markers.

- Create stably-expressing miR cell lines
- Leverage SBI’s highly-regarded lentivectors
- Obtain accurate miR processing and efficient expression through the use of native precursor sequences
- Use copGFP and puromycin markers to identify desired clones
