MicroRNAs (miRNAs) are small, noncoding RNA molecules that direct posttranscriptional suppression of gene expression. They have been shown to act as key regulators in many basic biological processes such as development, cell proliferation, differentiation, and the cell cycle. Emerging evidence also implicates miRNAs in the pathogenesis of human diseases such as cancers, metabolic diseases, neurological disorders and infectious diseases.
Common miRNA research applications:
- miRNA profiling—identify differentially expressed mature miRNAs using qPCR in application areas like oncology, metabolic diseases, and autoimmune diseases
- miRNA quantitation—specific quantification of mature miRNAs using qPCR
- miRNA validation—confirm miRNA profiling results using qPCR
- miRNA functional analysis—miRNA mimics and miRNA inhibitors for functional studies
- Noncoding RNA (ncRNA) analysis—reliable detection and quantitation of non-coding human, mouse, or rat transcripts longer than 200 nucleotides.
- Small RNA analysis—detect and measure any small RNA
- pri-miRNA analysis—detect and measure primary miRNAs from human, mouse, or rat species
Applied Biosystems TaqMan MicroRNA Assays are innovative tools for miRNA research-from isolation through discovery, profiling, quantitation, validation and functional analysis. We have developed two methods for sensitive, precise quantification and profiling of miRNA using real-time PCR TaqMan probe-based analysis.
- TaqMan Advanced miRNA Assays use ligation-based universal reverse transcription for an easy streamlined workflow.
- TaqMan MicroRNA Assays — this “classic” version employs target-specific stem-loop reverse transcription primers for 3’ extended templates for highly sensitive detection.
Real-time PCR microRNA workflow:

These kits use a rapid procedure to isolate total RNA, including small RNAs such as miRNA, small interfering RNA (siRNA), and small nuclear RNA (snRNA), from tissues and cells. We can address a small number of targets or handle samples that require high throughput. - TaqMan miRNA ABC Purification Kit
For use with the classic TaqMan MicroRNA assays, obtain high quality miRNA for sensitive and specific miRNA expression analysis from difficult sample types including blood, serum, plasma, FFPE, solid tissues, cultured cells, saliva, or urine
