Maximize safety with Minicircle Technology—episomal expression free from foreign DNA Get all the advantages of Minicircle Technology with the pMC.EF1α-MCS-IRES-RFP-SV40polyA Parental Minicircle Cloning Vector (Cat.# MN531A-1). This Minicircle Cloning Vector contains the necessary sequences to generate a minicircle, and a moderate EF1α promoter upstream of an MCS, so you can clone-in your gene-of-interest and get medium expression levels in most cell types, including primary and stem cells. In addition, this vector co-expresses RFP from the EF1α promoter for coordinated expression of the RFP reporter with your gene-of-interest, facilitating identification of transfectants via RFP imaging.

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.

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).

Achieve sustained expression from minicircles after transfection in vitro and in vivo
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.
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.
