Abstract: The present invention relates to the field of chromatography and more specifically to producing protein affinity chromatography resins comprising affinity ligands based on a N-terminal fragment of a split intein, such as DnaE from Nostoc punctiforme, as well as methods for using the same. The N-terminal fragments are produced in inclusion bodies in bacterial cells.

Abstract: The present disclosure is directed to a method for separating supercoiled plasmid DNA (pDNA) from a liquid sample. the method comprising the steps of: (a) adding a liquid sample comprising pDNA to a first chromatography material comprising (i) an anion exchange chromatography ligand for binding to pDNA and (ii) a support material allowing convective flow through the first chromatography material, wherein the liquid sample originates from a cell culture harvest and has been subjected to a step of removing RNA before step (a): (b) eluting a liquid sample. comprising a purified mixture of supercoiled pDNA and open circular pDNA, from the first chromatography material: (c) adding the liquid sample from step (b) to a second chromatography material comprising a ligand that binds to pDNA and enables selective separation of supercoiled pDNA from open circular pDNA: (d) eluting the purified supercoiled pDNA from the second chromatography material: wherein the supercoiled pDNA eluted in step (d) has a purity degree of at least 95% without use of any further chromatography material than said first and second chromatography materials. Steps (a)-(d) and any intermediate steps can be completed within 5 hours. Further disclosed are uses of supercoiled pDNA obtained by said separation method.
