Maximize safety with Minicircle Technology—episomal expression free from foreign DNA Get all the advantages of Minicircle Technology with the pMC.CMV-MCS-EF1α-GFP-SV40polyA Parental Minicircle Cloning Vector (Cat.# MN511A-1). This Minicircle Cloning Vector contains the necessary sequences to generate a minicircle, and a strong CMV promoter upstream of an MCS, so you can clone-in your gene-of-interest and get high expression levels in most commonly-used cell lines (i.e. HeLa, HEK293, HT1080). In addition, this vector includes GFP driven by the moderate EF1α promoter to facilitate identification of transfectants via GFP imaging. pMC.EF1α-MCS-SV40polyA Parental Minicircle Cloning VectorAbout Minicircle Technology
  • Episomal expression sustained over weeks
  • Foreign DNA-free
  • More efficient transfections from small plasmid size
  • Unlimited insert size
  • Optimized coli minicircle production strain
  • Works in vitro and in vivo
When you want sustained transgene expression without introducing any foreign DNA—such as for model animal and gene therapy development—Minicircle Technology is a great gene expression option. Produced as small excised, circular DNA fragments from a parental plasmid, the non-viral, episomal Minicircle expression cassette is free of any bacterial plasmid DNA sequences, and comes with a variety of promoter and reporter combinations. Their small size facilitates more efficient transfection than what’s possible with standard-sized plasmids, and, while Minicircles do not replicate with the host cell, expression lasts for 14 days or longer in dividing cells, and can continue for months in non-dividing cells. Product Note: Parental minicircle plasmids and the ZYCY10P3S2T Producer Bacterial Strain are available for purchase by not-for-profit researchers only. Commercial users may purchase pre-made, ready-to-transfect minicircle DNA only. SBI also offers custom parental plasmid cloning and minicircle DNA production to both not-for-profit and commercial end users—contact services@systembio.com for additional details. For any other purposes, including the ability to buy the parental MC production system, commercial users should contact SBI at tech@systembio.com for further information.

How It Works

How It Works

Generating minicircles from the parental cloning vector

To generate minicircles that are ready for transfection, you need your Minicircle Cloning Vector with your insert (gene, promoter-gene cassette, small RNA, etc.), SBI’s optimized, ready-to-transform ZYCY10P3S2T E. coli Minicircle Producer Strain (Cat.# MN900A-1), and arabinose (Cat.# MN850A-1).

Minicircles are produced from the full-sized Parental Minicircle using PhiC31 Integrase, which mediates a recombination event between the PhiC321 attB and attP sites on the parental plasmid (Figure 1). This reaction results in two products—the minicircle, which is now free from any bacterial DNA sequences—and the parental plasmid. To get rid of the parental plasmid, the I-SceI endonuclease recognizes and acts on the I-SceI sites on the parental plasmid, resulting in degradation of the parental plasmid.

How to generate minicircles from the parental minicircle vector

More about the ZYCY10P3S2T E. coli Minicircle Producer Strain

The Minicircle Producer Strain harbors an arabinose-inducible system to express the PhiC31 integrase and the I-SceI endonuclease simultaneously. The ZYCY10P3S2T strain also contains a robust arabinose transporter LacY A177C gene. Adding arabinose to the media turns on expression of the PhiC31 integrase and endonuclease genes, resulting in separation of the Parental Minicircle Plasmid into the individual minicircle and parental plasmids (from the PhiC31 Integrase activity), and the degradation of the parental plasmid (from Sce-1 endonuclease activity).

Use minicircles to get easy, sustained transfection in most cell types

Figure 1. Easy, sustained transfection in most cell types. Transfection of 1 μg of minicircle DNA (pMC.CMV-MCS-EF1-GFPSV40PolyA, Cat.# MN511A-1) into HEK293 cells delivers over one week of robust gene expression.

Use minicircles to express transgenes for weeks in animal models

Figure 2. Express transgenes for weeks in animal models. (A) Hydrodynamic tail vein injection of 2 µg and 4 µg of minicircle DNA (CMV-GFP-Luc) into mice shows excellent expression after 48 hours. (B) Minicircle-delivered transgenes retain robust expression that can last for weeks compared to transgenes that are delivered using plasmid DNA, where expression is rapidly lost. In this study, 40 µg of minicircle DNA was introduced into mice via hydrodynamic tail vein injection.
