Freely soluble in water, practically insoluble in anhydrous ethanol. IDENTIFICATION A. It gives the reactions of chlorides. B. It gives the reactions of sodium.TESTS Solution S: If the substance is in the form of pearls crush before use. Dissolve 20.0 g in carbon dioxide-free water prepared...
The maximum adsorption capacities (at 95% confidence limits) of activated charcoal were 25 (18.42; 31.5) mg and 200 (175.158; 224.84) mg diazepam/g activated charcoal at pH values 1.2 and 6.8, respectively. In case of 10 and 25% ethano...
Most other glycerophospholipids (phosphoethanolamines, phosphatidic acids and phosphoglycerols) are less soluble in ethanol, but solutions up to 1–2 mg/mL should be obtainable, using sonication to aid dispersion if necessary. Labeling of cells with fluorescent phospholipids can be enhanced b...

The C-terminal domain (CTD) of the largest subunit of RNA polymerase II (Pol II) is a regulatory hub for transcription and RNA processing. Here, we identify PHD-finger protein 3 (PHF3) as a regulator of transcription and mRNA stability that docks onto Pol II CTD through its SPOC domain...

For histological analysis, tumors and vital organs were dehydrated with 95% ethanol twice for 30 min, and then soaked in xylene for 1 h at 60–70 °C followed by paraffin for 12 h. The paraffin embedded tissues were sectioned into 7-μm slices, dewaxed on microscope slides, ...
Ethanol quantificationDifferential pH measurement deviceThe aim of this study is to develop a method for determining full range of ethanol concentrations with high accuracy and low cost. Since applying other methods (e.g. non-enzymatic, optical...etc) suffer from difficulties, it was intended to ...
ethanolvacuum dryingfreeze dryingProteins were produced by fed-batch fermentation of Saccharomyces cerevisiaecultivated on date solution. Protein content was 52.5% (dry basis). Protein solubility was studied as a function of pH, NaCl concentration, and solvent. The minimum protein solubility was at pH...
