WebOct 15, 2015 · High-yield pDNA production relies on synergy among host strain, plasmid, media, and induction strategy. Screening as many variables as quickly and cost- effectively as possible is the main goal during development. Transfer from small-scale technology to manufacturing scale requires management of the scale-up process. WebPlasmid-EZ is an end-to-end solution that enables cost-effective, rapid, and high-throughput sequencing of whole plasmids. With conventional methods, only important regions of plasmids are sequenced which can fail to detect unwanted changes in other areas during replication and leave you to piece together an entire plasmid map.
