چکیده

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.

The Combination Process for Preparative Separation and Purification of Paclitaxel and 10-Deacetylbaccatin III Using Diaion® Hp-20 Followed by Hydrophilic Interaction Based Solid Phase Extraction

There is no other naturally occurring defense agent against cancer that has a stronger effectthan paclitaxel, commonly known under the brand name of Taxol®. The major drawback for themore widespread use of paclitaxel and its precious precursor, 10-deacetylbaccatin III (10-DABIII), is that they require large-scale extraction from different parts of yew trees (Taxus species),cell cultures, taxane...

Purification of plasmid DNA vectors by aqueous two-phase extraction and hydrophobic interaction chromatography.

The current study explores the possibility of using a polyethyleneglycol(PEG)-ammonium sulphate aqueous two-phase system (ATPS) as an early step in a process for the purification of a model 6.1 kbp plasmid DNA (pDNA) vector. Neutralised alkaline lysates were fed directly to ATPS. Conditions were selected to direct pDNA towards the salt-rich bottom phase, so that this stream could be subsequentl...

Expression, purification and kinetic characterization of recombinant benzoate dioxygenase from Rhodococcus ruber UKMP-5M

In this study, benzoate dioxygenase from Rhodococcus ruber UKMP-5M was catalyzed by oxidating the benzene ring to catechol and other derivatives. The benzoate dioxygenase (benA gene) from Rhodococcus ruber UKMP-5M was then expressed, purified, characterized, The benA gene was amplified (642 bp), and the product was cloned into a pGEM-T vector.The recombinant plasmid pGEMT-benA was digested by d...

Hydrophobic Interaction Chromatography: Fundamentals and Applications in Biomedical Engineering

Hydrophobic interaction chromatography (HIC) a powerful technique used for separation and purification of biomolecules. It was described for the first time by Shepard & Tiselius (1949), using the term “salting-out chromatography”. Later, Shaltiel & Er-el (1973) introduced the term “hydrophobic chromatography”. Finally, Hjerten (1973) described this technique as “hydrophobic interaction chromato...
