Fine-Tuning Gene Expression Vectors (Custom miR-Tuners)

Conventional mammalian expression systems rely on the usage of strong viral promoters (i.e. CMV and SV40) which over-express the gene of interest (GOI). However, over-expression of a foreign gene can lead to detrimental effects in the cell and importantly, fails to replicate normal physiological gene expression levels. To address this issue, miR-Tuner Vectors can be used to precisely fine-tune transgene expression levels in a predictable manner.

miR-Tuners are short, synthetic miRNA response element sequences which reside in the 3’ UTR of the GOI. These sequences are responsive to a native miRNA species which is widely expressed in many human and mouse cells. Using the miR-Tuner Low, Med or Hi will allow for precise low, medium or high expression levels of the GOI, respectively.

abm offers a variety of miR-Tuner Vector products which can precisely and predictably control transgene expression levels in mammalian cells. These products include ready-to-clone miR-Tuner MCS Lentiviral Vectors and Custom Cloning Services of your GOI into a set of miR-Tuner Vectors/Lentiviruses.


Fine-tuning transgene expression levels in mammalian cells for:

  • Engineered genetic circuits and cell lines
  • Studying physiological and biochemical changes

Supporting Data

The reporter gene Firefly Luciferase was cloned into the set of miR-Tuner Lentivectors and transfected into HEK293T cells. Following 24h incubation, the cells were lysed and subjected to a Luciferase Assay with the output RLU measured on a standard plate reader. As seen below, miR-Tuner Vectors were able to predictably control Firefly Luciferase gene expression.
