Minicircle Technology

Get sustained, episomal gene expression free from foreign DNA—great for model animal generation and gene therapy research

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.
