PhD Scholarship for Molecular Ecology and Ecological Epigenetics ...

A (partial) 454 based transcriptome sequence is available, and more than 10.000 SNPs, hundreds of EST-SSRs, and routine protocols for DNA methylation study are available for this species. Recently, an ecological epigenetics line has been started up, which aims to investigate in what way DNA methylation could be important for rapid adaptation to rapidly changing environmental conditions. A central theme in all lines is how inbreeding affects gene expression, and how inbreeding might disrupt epigenetic regulation mechanisms. The institute is well equipped, has a very modern molecular lab, and [more...]

DNA was isolated from human tissue by using the Maxwell 16 Tissue DNA Purification Kit (Promega, Madison, WI, USA) according to the manufacturer’s protocol. DNA concentrations were measured by using a UV spectrophotometer (NanoDrop, Wilmington, DE, USA). The 16S rRNA and methanol dehydrogenase subunit 1 (GeneID YP_744165.1) genes of G. bethesdensis were analyzed by using a PCR and primer sequences 16S-forward: 5'-TCGGGTGGGCACTCTAAAGG-3', 16S-reverse: 5'-GCATCACTGCCTAGCTTCCC-3', MDH-forward: 5'-CCGCAATACGGTCAATTCG-3', and MDH-reverse: 5'-GCCGATCTTCCAGGTTTCTTC-3'.

To obtain these structures, a new, efficient solid-phase synthesis protocol was developed as well. To determine the binding affinity and selectivity of these compounds among all possible 4-base pair sequences of DNA, a high throughput (HT), fluorescence intercalator displacement (FID) assay was employed. The FID results indicate that these compounds are good DNA minor groove binders as predicted (more than 50% fluorescence decrease at 10 μM for A/T only sequences); the amidine group improves the binding affinity and selectivity compared to amino acid-benzimidazole conjugates without an [more...]

DNA was extracted from frozen cardiac muscle samples. The SCAP 2386A>G genotyping was based on PCR amplification, restriction enzyme analysis and DNA electrophoresis. The DNA samples were amplified by PCR, using the primers 5'-TTGTGCTGCGCGGCCACCTCA-3' and 5'-AGGAGGAAAGGGCAGCCGCAC-3'. PCR was performed in a volume of 50 μl. Cycle conditions were 94°C for 4 min, then 28 cycles of 94°C for 1 min, 64°C for 1 min and 72°C for 1 min, with a final extension step of 5 min at 72°C in a PTC-225 thermal cycler (MJ research, Massachusetts, USA). 10% DMSO was included in PCR reaction.

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...]

JoVE: Electroeluting DNA Fragments (Video Protocol)

Purified DNA fragments are used for different purposes in Molecular Biology and they can be prepared by several procedures. Most of them require a previous electrophoresis of the DNA fragments in order to separate the band of interest. 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. Thus, selecting a method will depend mostly of what is available in the laboratory. The [more...]

Engineering Mini project: DNA COMPUTERS

After seven days of intensive laboratory work, Adleman's test-tube contained the answer to the problem, subsequently visible as a series of dark bands on a DNA sequencing gel. On the face of it, it might hardly seem worth the bother, especially as Adleman already knew the answer before he started the experiment. But this was much more than a curious laboratory stunt. During the initial 'linking-up' stage of the process, Adleman's test-tube computer effectively performed an astonishing 10^14 calculations. And it did so with the consumption of only a tiny amount of energy, and in a tiny [more...]

Next Generation Sequencing » Tweaking the 454 sequencing protocol ...

In the new issue of Biotechniques, a paper by Maricic and Pääbo (login may be required) describes how a change to the standard 454 sequencing protocol  can dramatically increase the size of the library of DNA that goes into the actual sequencing reaction. The trick used is to replace the last step in the library preparation where single stranded DNA is released from streptavidin beads. The original 454 protocol employes NaOH denaturation for this step, but the researchers found that this procedure results in a loss of over 99% of the DNA. However, When they replaced the NaOH denaturation [more...]
