Toward Therapeutic Plasmids Purification by Hydrophobic Interaction Membrane Chromatography

Purification of Plasmid (pVaxLacZ) by Hydrophobic Interaction Chromatography

This paper describes a method for the plasmid DNA purification, which includes an ammonium sulphate precipitation, followed by hydrophobic interaction chromatography (HIC) using Phenyl Sepharose 6 Fast Flow (low sub). The use of HIC took advantage of the more hydrophobic character of single stranded nucleic acid impurities as compared with double-stranded plasmid DNA.

Purification of Mycobacterium bovis BCG Tokyo antigens by chromatofocusing, lectin-affinity chromatography, and hydrophobic interaction chromatography.

A combination of chromatofocusing, lectin-affinity chromatography, and hydrophobic interaction chromatography resulted in a simple purification of protein antigens of Mycobacterium bovis BCG Tokyo culture filtrate. Identification was established on the basis of chromatographic separation, sodium dodecyl sulfate-polyacrylamide gel electrophoresis determination of molecular weights, and N-termina...

Hydrophobic interaction chromatography for purification of monoPEGylated RNase A.

The chromatographic methods used for the purification of PEGylated proteins are mainly Size Exclusion (SEC) and Ion Exchange Chromatography (IEX). Although the PEGylation affects the protein hydrophobicity, Hydrophobic Interaction Chromatography (HIC) has not been extensively applied for the separation of these proteins. Purification of monoPEGylated Ribonuclease A (RNase A) using HIC is studie...
