[Maintenance of Plasmid Expression in vivo Depends Primarily on the CpG Contents of the Vector and Transgene]

Plasmid-mediated gene remedy, being a protected and comparatively cheap therapeutic technique, is stricken by a quick silencing of transgene expression. The silencing severely reduces the long-term effectivity of plasmid vectors. We have now earlier constructed a low-CpG pMBR2 plasmid vector supporting extended expression of transgenes in mesenchymal stem cells in vitro. Lengthy-term expression from the […]

Synthetic control of plasmid replication enables target- and self-curing of vectors and expedites genome engineering of Pseudomonas putida.

Synthetic control of plasmid replication enables target- and self-curing of vectors and expedites genome engineering of Pseudomonas putida.

Genome engineering of non-conventional microorganisms requires the event of devoted artificial biology instruments. Pseudomonas putida is a Gram-negative, non-pathogenic soil bacterium broadly used for metabolic engineering owing to its versatile metabolism and excessive ranges of tolerance to several types of stress. Genome enhancing of P. putida largely depends on homologous recombination occasions, assisted by helper plasmid-based expression of genes encoding […]

Effective removal of a range of Ti/Ri plasmids using a pBBR1-type vector having a repABC operon and a lux reporter system.

Effective removal of a range of Ti/Ri plasmids using a pBBR1-type vector having a repABC operon and a lux reporter system.

Ti and Ri plasmids of pathogenic Agrobacterium strains are stably maintained by the operate of a repABC operon and have been categorised into 4 incompatibility teams, particularly, incRh1, incRh2, incRh3, and incRh4. Removing of those plasmids from their bacterial cells is a vital step in figuring out strain-specific virulence traits and to assemble strains helpful […]
