New ligands for plasmid DNA affinity purification

Molecular therapies and vaccines based on purified plasmid DNA (pDNA) are increasingly being established as promising alternatives to medical classical treatments. The expected wide application of these therapies requires the large-scale production and purification of plasmids. Recent years, had witness the development of new methods for plasmid purification, based on aqueous two-phase systems (ATPS) offering additional advantages like technical simplicity and the use of inexpensive equipment and chemicals. This project is going to study the molecular recognition mechanism and binding [more...]

The Purification of Plasmid DNA for Clinical Trials Using Membrane ...

ABSTRACTMembrane chromatography offers a good solution to the challenge of developing an efficient chromatographic procedure for plasmid DNA purification. The large convective pores of anion exchange membranes allow plasmid DNA to access all the anionic binding sites of the membrane at high flow rates. Here we demonstrate that the pIDKE2 plasmid can be purified from a recombinant Escherichia coli lysate using a Sartobind D membrane combined with size exclusion chromatography to render material with 95% purity and an average yield of 50%. This process yields therapeutically suitable plasmid [more...]

Quick Kit for Bacterial Total DNA Isolation

This kit is a very quick and easy one for bacterial total DNA (chromosome and plasmid) isolation with fewer steps. It takes less than 15 min. for sample to be ready for loading on agarose gel electrophoresis. Using this kit, the plasmid takes only one from its three forms after isolation, which a appears as one clear and sharp band in the agarose gel after electrophoresis (in addition to chromosomal band). Making the detection of plasmid in agarose is much easier and also determined, if the sample has more than one plasmid. This kit is able to isolate total DNA from bacteria cell with high [more...]

HIV Vaccine | Biology in Action

“The prime is a plasmid DNA vaccine, PENNVAX™-G, and the boost is a virus vector vaccine, Modified Vaccinia Ankara-Chiang Mai Double Recombinant (MVA-CMDR). Together, the vaccines are designed to deliver a diverse mixture of antigens for HIV-1 subtypes A, B, C, D and E”. Taken separately, the strategies have been proven safe. Several precautions have to be taken because the study is the use of different HIV antigens during the priming (A-D) and boosting A/E. The DNA vaccine was designed at the University of Pennsylvania and licensed by Inovio Pharmaceuticals. The vaccine is based off a [more...]

Biological activity of the purified plasmid was confirmed in vivo; immunized mice developed a positive antibody response against all HCV structural antigens.

Variants of PCR (1)

The bacteriophage T4 DNA polymerase was also tested shortly after the first reports of PCR. It has a higher fidelity of replication than the Klenow fragment. Since it is also destroyed by heat, it has seen little use since the development of thermostable polymerases. The DNA polymerase from Thermus aquaticus (or Taq), was the first thermostable polymerase used in PCR, and is still the one most commonly used. The enzyme can be isolated from its 'native' bacterial source, or from a cloned gene expressed in E. coli. The Stoffel fragment is produced from a truncated gene for Taq polymerase, [more...]

Then, this band is excised out from an agarose or acrylamide gel and purified by using either: binding and elution from glass or silica particles, DEAE-cellulose membranes, "crush and soak method", electroelution or very often expensive commercial purification kits.
