Plasmids—Part 2: Perfecting Plasmid Production for IVT mRNA ...

WebLinearization is achieved by mixing the plasmid DNA with a restriction enzyme in a reaction buffer 4 and subsequent incubation at 37 °C for 4 hours. Optionally, the reaction is stopped by the addition of EDTA or heat inactivation at 65 °C. Impurities such as the restriction enzyme, BSA, DNA fragments, endotoxins and others are then removed. WebThis post is Part 2 of a series of Zone blogs featuring DNA plasmids used to produce in vitro transcribed (IVT) mRNA. Part 1, posted on June 8, 2024, provided historical perspectives on the discovery of plasmids, as well as descriptions of how these circular double-stranded DNAs enabled recombinant DNA technology and now IVT mRNA production.

WebFor transformation of foreign DNA, E. coli prefer circular plasmid while Bacillus subtilis get higher transformation efficiency with linearized plasmid. What is the reason for that? WebBackground Information The final step in the construction of a recombinant plasmid is connecting the insert DNA (gene or fragment of interest) into a compatibly digested vector backbone. This is accomplished by covalently connecting the sugar backbone of the two DNA fragments.

WebOur goal is to use the enzyme Eco RI to insert the gene into the plasmid. First, we separately digest (cut) the gene fragment and the plasmid with Eco RI.
