the dna molecule has been known to be the cellular target for many cytotoxic anticancer agents for several decades. understanding how drug molecules interact with dna has become an active research area in the interface between chemistry, molecular biology and medicine. dna extraction has been suggested as a main step affecting molecular dna technology such as pcr and pcr-based methods. therefor...

BACKGROUND Radix et Rhizoma Rhei has a gastric mucosal protective effect, major anti-gastritis and anti-peptic ulcer active constituents were emodin, aloe-emodin, chrysophanol, rhein, etc. The objective of the study was the extraction process of total anthraquinones in Radix et Rhizoma rhei and their antilipemic effects. MATERIALS AND METHODS Orthogonal experiment, UV spectrophotometry and co...

The aim of this study was to evaluate the repeatability and performance of 4 methods of extracting DNA from Staphylococcus aureus (SAU) and the gene encoding bovine mitochondrial cytochrome B (BMCB) in milk samples from cows with subclinical mastitis for use in amplification by real-time polymerase chain reaction. Two milk samples were obtained from cows naturally infected with S. aureus and su...
