How It Works
How the QuantiMir Kit Works
The QuantiMir Kit enables robust miRNA quantitation through a simple and efficient workflow
Highly efficient poly-A tailing and reverse transcription in a single reaction tube provides uniform cDNA synthesis of miRNAs. The optimized reaction conditions and buffer components maximize cDNA yield when starting with several micrograms down to picograms of input total RNA. The universal 3′ tag sequence incorporated during reverse transcription enables easily scalable and accurate miRNA expression analysis by qPCR—profile thousands of different miRNAs from a single reverse transcription reaction.
- Tag all small RNAs with a poly-A tail
- Anneal an oligo-dT adaptor
- Reverse transcribe to create first-strand cDNA
The result is a cDNA pool of anchor-tailed miRNAs that are ready for qPCR.
Create custom miRNA assays
To design your own miRNA assays, simply synthesize an oligo using the sequence of the mature miRNA you’d like to profile as the forward primer in your miRNA qPCR assay, and use with the universal reverse primer included in the QuantiMir Kit.

Supporting Data for the QuantiMir Kit
Converting miRNA into cDNA for accurate qPCR profiling and quantitationThe QuantiMir Kit is sensitive
Figure 1. The QuantiMir Kit is highly sensitive and enables measurement across a wide dynamic range. (A) Starting with total, Trizol-extracted RNA or fractionated small RNA samples you can measure from several micrograms down to picograms of input RNA with excellent accuracy. (B) You can also detect differential miRNA expression across a dynamic range of at least 6 logs.
The QuantiMir Kit is accurate
Figure 2. The QuantiMir Kit is accurate. We used the QuantiMir Kit to synthesize first strand cDNAs from 18 different human tissues: adipose, bladder, brain, cervix, colon, esophagus, heart, kidney, liver, lung, ovary, placenta, prostate, skeletal muscle, small intestine, spleen, testes, and thymus. The cDNAs were balanced to yield equal Ct values for the U6 snRNA normalizing transcript (bottom left plot, green bars). Real-time PCR results demonstrate that the normalizing snRNA is uniformly expressed across the 18 tissues examined. As expected, assays for miR-1 are show specific expression in heart and musculoskeletal tissues (top left plot, red bars) whereas assays for miR-122 show specific expression in the liver (top right plot, blue bar).
Use the QuantiMir Kit to profile miRNAs from cancerous and normal tissues
Figure 3. Use the QuantiMir Kit to profile miRNAs from cancerous and normal tissues. Example of quantitative miRNA profiling of nine miRNAs in five different normal and tumor-derived samples.
Measure both siRNA and mRNA knockdown in a single QuantiMir cDNA sample
Figure 4. Measure both siRNA and mRNA knockdown in a single QuantiMir cDNA sample. A time-course using anti-p53 shRNA-directed knockdown of the endogenous p53 mRNA transcript demonstrates how the QuantiMir Kit can be used to measure both p53 siRNA (orange bars) and p53 mRNA (blue line) via qPCR.
