There is extensive experimental evidence that oxidative damage permanently occurs to lipids of cellular membranes, proteins, and DNA. In nuclear and mitochondrial DNA, 8-hydroxy-2' -deoxyguanosine (8-OHdG) or 8-oxo-7,8-dihydro-2' -deoxyguanosine (8-oxodG) is one of the predominant forms of free radical-induced oxidative lesions, and has therefore been widely used as a biomarker for oxidative stress and carcinogenesis.
2013/3/15 · A method based on closed-vessel MAE followed by ultra-HPLC/MS/MS detection was developed for rapid determination of atrazine and its degradation products in microporous mineral sorbents. The optimal extraction conditions were: 20 mL of methanol, continuous microwave irradiation for 15 min to maintain a steady extraction temperature of 80 °C.
2017/11/1 · The solution was filtered through 0.45 μm PTFE disk filters and injected into HPLC for analysis. Extractions were performed from the mucosa of each diffusion cell (n = 6) and are expressed as percentages. All average values of retention were tested by ANOVAα

Protein Expression and Purification is an international journal providing a forum for the dissemination of new information on protein expression, extraction, purification, characterization, and/or applications using conventional biochemical and/or modern molecular
2016/10/17 · Ultrapure water obtained from a Milli-Q water purification system (Bedford, MA, USA) was used in mobile phases, which were filtered through a 0.45 mm cellulose acetate (water) or polytetrafluoroethylene (PTFE) (acetonitrile) filter and degassed via ultrasound
2018/1/17 · The supernatant layer was syringe filtered using a 0.2-μm PTFE membrane before performing the experiments. Triplicate sample preparations were done on each sample, and two separate HPLC injections were carried out for each replicate preparation.
This chapter describes how a combination of high-performance liquid chromatography (HPLC) and exoglycosidase enzyme array digestions can deliver quantitative glycan analysis of sugars released from glycoproteins in sodium dodecyl sulfate-polyacrylamide
2021/1/4 · The resulted materials were then filtered through 0.45-μm PTFE membrane and washed with deionized water. For preparation of the microextraction fiber, hollow fibers (HF) with 2 cm in length were prepared and packed with the produced nanocomposite after drying overnight at room temperature.
Membrane Properties and Characterization for Zero-Gap CO2 Electrolyzers. Zero-gap electrolyzers are similar to fuel cells in design because the heart of the electrolyzer consists of two electrodes pressed against a membrane. These electrolyzers are called “zero-gap” bec..
