Synthetic miRNA Inhibitors and Antagomirs
miRNA Inhibitors are chemically synthesized, complementary, antisense single-stranded oligonucleotides which may bind to endogenous mature miRNA. Also available are miRNA Antagomirs, a type of miRNA inhibitor with chemical modifications to prevent degradation and increase transfection efficiency.
miRNA inhibitors and antagomirs block miRNA regulation of target gene expression by stable suppression and can knock down native miRNA expression in cells. They can be used in miRNA loss-of-function studies, miRNA target site identification and validation, and miRNA screening experiments.
- We offer a collection of synthetic miRNA Inhibitors and Antagomirs for knockdown of over 6000 miRNAs from human, mouse, and rat.
- Synthetic miRNA inhibitors are easily transfected into many cell types for immediate knockdown of mature miRNA.
- Antagomirs have chemical modifications to increase transfection efficiency and stability.

|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.
|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.
|Do I need to use an internal control primer for quantitative detection of miRNAs (the same as housekeeping primers which we use in qPCR for mRNAs detection)?
For human miRNA plates, the controls are as follows:
1) SNORD44, cat MPH00003
2) SNORD47, cat MPH00004
3) SNORD48, cat MPH00005
4) U6-2, cat MPH00001
