3'UTR miRNA Reporters and Cell Lines

abm has developed a comprehensive 3'UTR library of lentiviral vectors and viruses for all human genes, with a choice of luciferase or GFP reporter genes. Also available are ready-to-use 3'UTR reporter cell lines, which stably express the 3'UTR region of your gene of interest and a GFP or luciferase reporter.

One of the most reliable, quantitative methods for studying interactions between a specific miRNA and its putative binding site is by utilization of a reporter gene such as luciferase or GFP cloned upstream of a 3'UTR target. Interaction between an miRNA and the 3'UTR can be validated by observing whether a change in reporter gene expression occurs when miRNA expression vectors and/or miRNA inhibitors are co-transfected with the 3'UTR reporter construct.


  • Co-transfect with an miRNA expression vector or mimic. Interaction between the 3'UTR and miRNA is validated if decreased expression of the reporter gene is observed.
  • Assay for endogenous miRNA expression by transfecting the 3'UTR reporter vector into the cell line of interest. When co-transfected with a miRNA inhibitor, an attenuated or abolished interaction between the miRNA and the UTR of the Reporter Vector should be observed.
  • Investigate miRNA binding requirements using 3'UTR mutant reporters. Importance of a locus for miRNA binding can be determined by mutating that locus and observing if reporter expression is affected.
  • Use 3'UTR reporter cell lines for stable expression of the 3'UTR reporter construct from HEK293 cells.
