PlasmidSelect Xtra is a thiophilic aromatic adsorption chromatography resin with a selectivity that allows supercoiled covalently closed circular forms of plasmid DNA to be separated from open circular forms.

• PlasmidSelect Xtra allows for generic purification of supercoiled plasmid DNA
• PlasmidSelect Xtra allows for consistent purification results when scaling up from research scale to cGMP production
• Available in convenient prepacked formats for research, process development and quantitative and qualitative analysis of supercoiled plasmid DNA
• The hydrophilic nature of the base matrix ensures low levels of non-specific binding
• This resin is a BioProcess resin supported for industrial applications
