Adenovirus miRNA Expression

miRNA mimics are used for functionality assessments and serve as a useful exogenous tool for gain-of-function studies. abm's miRNA-expressing Adenoviruses have excellent transduction efficiency, leading to high levels of expression in the host cell.

To serve all your needs, we offer miRNA adenoviruses expressing both primary miRNAs and mature miRNAs. Expression of the primary miRNA means that the entire region surrounding the miRNA will be expressed, and both arms of the precursor will be processed, just as it would be endogenously. Our mature miRNA expression vectors are specially designed for robust expression and processing of the mature miRNA.


Key Features

  • We offer a collection of over 6500 mature and primary miRNAs from human, mouse, and rat.
  • Adenoviral delivery for high level, transient expression of miRNA inhibitors.
  • Adenovirus has a broad host range and high transduction efficiency.

FAQs

What is the Sanger miRBase Sequence Database?
miRBase is a sequence database that has been established by the Sanger Institute. Each entry in the microRNA Registry represents a predicted hairpin portion of a microRNA transcript (termed mir in the database), with information on the location and sequence of the mature microRNA sequence (termed miR). The database provides microRNA gene hunters with unique names for novel microRNA genes prior to publication of results and a searchable database of published microRNA.
When was the latest update of your array sequences?
The content of our arrays has been updated to miRBase Release 16.0.
Can I quantify mature miRNA in total RNA using your cDNA synthesis and kit and qPCR master mix?
Yes, that is what it is designed for.
Which genes are targeted by a specific miRNA?
You can search for predicted and validated miRNA target genes at http://mirbase.org/.

Just type in your miRNA name (eg. hsa-mir-145) or accession number in the search bar and look for the targeted genes.
pLenti-III-miR-Off system or LentimiRa system uses blank vector for control, but I usually use scrambled control for si-RNA experiments. Is it supported to use blank control not scrambled for miRNA experiments?
Both scrambled and blank controls are effective negative controls. However, there are debates over off-target effects when using scrambled sequences. By using a blank vector as negative control, the off-target effect can be eliminated. If your experiment requires a scrambled control over a blank control, we can custom make that for you as well upon request.
Are the inserts in our vector in a pri-miRNA format or a mature miRNA format?
Majority of our inserts are in the pri-miRNA format (about 500-600bp in size). If the miRNA is found in a cluster, the insert will then be the mature miRNA format (about 150bp in size) to ensure that the construct is only expressing one miRNA.

If the R in mir is big (miR) and the accession# is MIMA#########, then it’s typically the Mature format.
If the r in mir is small (mir) and the accession# is MI#########, then it’s typically the pre-miRNA format.
This information can also be found on the "insert type" section of this product webpage.
How does miRNA inhibitor adenovirus work?
The miRNA inhibitor is in the form of a short hairpin which is complementary to the mature miRNA sequence that it targets. Its expression is under the control of the H1 promoter in an Adenovirus vector. The packaged adenovirus can be used to transfect your target cells and deliver the miRNA inhibitor into the cells and knockdown its target mature miRNA.
Are both the pre-miRNA and GFP under the same CMV promoter? If yes, is there a translational cleavage site between the two?
Yes, both the pre-miRNA and GFP are under the same CMV promoter.

There is no translational cleavage site between the two.

The transcription termination site is after the pre-miRNA, so both GFP and the pre-miRNA are transcribed together, thus making GFP an actual transcription reporter for the miRNA. The pre-miRNA region of the mRNA folds over on itself and forms a stem loop structure which will be processed in the cell by the Drosha/Pasha enzymes and cleaved from the GFP portion of the mRNA.
