The pH of the medium was measured at the end of the exponential growth phase. The buffering capacity of the buffers used was adequate to maintain a specific pH during the logarithmic growth phase and thus for determination of the relationship of specific growth rate and pH. Specific growth ...
(based on anhydrous substance); Processed cheese 40(based on anhydrous matter); Jam, jelly, orange peel jelly, so that the Ph value is maintained 2.8 ~ 3.5; Canned ripe peas 150mg/kg(used alone or in combination with sodium bicarbonate, measured in sodium, without adding hardener and ...
Residual fluoride content of reagents was observed to restrict the use of some buffers and reagents in low-level work. The optimum pH for low-level fluoride determinations was found to be around 5, which can be maintained by a sodium acetate-acetic acid buffer. Of the complexing agents ...
The reaction was maintained at pH 4.8 with 0.01 M HCl. After 1 h, sodium acetate to a final concentration of 0.5 M was added to quench the reaction, and the solution was stirred for an additional 1 h. UV scanning from 190 to 260 nm was performed to determine the ...
Horseradish peroxidase was tested to determine if it catalysed any reaction between coal and hydrogen peroxide. Experiments were performed in aqueous buffers of pH 5.0, 6.5 or 8.0 and used either Wyodak, Beulah Zap, Texas lignite, Mississippi Wilcox lignite or solubilized Mississippi Wilcox lignite....
When a person exercises, muscle contractions produce lactic acid. Moderate increases in lactic acid can be handled by the blood buffers without decreasing the pH of blood. However, excessive amounts of lactic acid can overload the blood buffer system, ...
Iron-detected chromatograms of Fe(ATP) using 50 mM (A) and 20 mM (B) ammonium acetate pH 6.5 mobile phases. All traces were from samples containing 1 µM FeSO4 + the following (final) µM concentrations of Na2ATP.A: (a) 0; (b) 5; (c) 10; (d) 25; (e) 50; (f)...
Proteins were extracted from isolated rat liver nuclei with 0.15 M NaCl and 0.35 M NaCl at pH 8.0. The number of phosphoproteins in these extracts was determined by labeling with 32P and autoradiography after two-dimensional gel electrophoresis. Two proteins, B22p and B24p, contained small amoun...
The reaction was carried out in a buffered solution containing 50 mM sodium phosphate, 100 mM KCl, 0.5 mM EDTA, pH 7.0, in a 1 L bottle fluxed with filter-sterilized nitrogen, at 20 °C, to which deoxygenated solutions of reagents were added anaerobically. Before PEG ...
All the reaction buffers were filtered using 0.02 µm filters. Monomeric FUS-LC (50 µM in 20 mM phosphate, pH 7.4) in the absence and presence of 250 mM NaCl was used for measurements at room temperature. Csat estimation Droplet reactions (200 µM FUS-LC) were induced...
