Maintenance of genetic purity of a hybrid is essential to exploit its full potential. Genetic purity is generally assessed by conducting grow out test (GOT) where morphological and floral characters are analyzed, however results may be influenced by the environment. Further, it is expensive and time consuming. DNA based markers are rapid, reliable and cost effective for hybrid purity assessment...

We describe the complete process of AcroPrep Advance Filter Plates for 96 plasmid preparations, starting from prokaryotic culture and ending with high purity DNA. Based on multi-well filtration for bacterial lysate clearance and DNA purification, this method creates a streamlined process for plasmid preparation. Filter plates containing silica-based media can easily be processed by vacuum filtr...

A method for large scale isolation of a native deoxyribonucleohistone complex from yeast is described. Crude chromatin, obtained after disrupting yeast cells at low ionic strength, contains a large amount of lipids, partially due to contaminating membranes. Most of them are removed by a Triton X-100 treatment, followed by step-gradient centrifugation. About 90% of the pellet may be solubilized ...

Aniline of unknown purity has been reported to induce spleen hemangiosarcoma in rats. Aniline has been found to be negative in terms of mutagenicity in both bacteria and yeasts. We have found that both commercial (already rather pure) and repurified aniline are clearly positive to a similar extent in inducing DNA damage in vivo in liver and kidney of rats. Both the commercial and repurified pro...

DNA isolation is a crucial step of conducting genetic studies in any organism. However, this process is quite difficult when studying fungi because of the need to damage the fungal cell walls of specific structures. In this study, we developed a method for the rapid and efficient isolation of fungal DNA based on simultaneous mechanical and enzymatic cell wall degradation. There are several typi...

Characterization and selection of olive clones for the production of olive oil is essential in Turkey because of its profitable exploitation. AP-PCR (Arbitrarily-Primed PCR) is a technique that can distinguish the genetic relationship among plant species and other organisms. In this study, AP-PCR approach was used in order to determine the genetic relationship of different six olive clones. The...

We compared three different protocols for DNA extraction from horse peripheral blood mononuclear cells (PBMC) and lung fragments, determining average final DNA concentration, purity, percentage of PCR amplification using beta-actin, and cost. Thirty-four samples from PBMC, and 33 samples from lung fragments were submitted to DNA extraction by three different protocols. Protocol A consisted of a...

DNA extraction methods for genotyping non-invasive samples have led to great advances in molecular research for ecological studies, and have been particularly useful for analyzing threatened species. However, scarce amounts of fragmented DNA and the presence of Taq polymerase inhibitors in non-invasive samples are potential problems for subsequent PCR amplifications. In this study we describe a...
