(drift tube), and 2L (nitrogen)/min. The mobile phase gradient started at 70% acetonitrile, decreased to 20% acetonitrile in 25min, and was held for 5min at 20% to clean the column. The column temperature was set at 40°C. The method achieved good separation of a mixture containing ...
Test for cyanogenic glycosides. About 2 g of total extract with adequate water was mixed in a test tube, and then the sodium-impregnated paper was added. The test result is positive when the color of the paper is changed from yellow to red. Cell culture and induction of insulin-resistant ...
of all things, an airplane kit. He died in a test flight in one in 1935, but Howard Anthony kept the company going. Right after World War II, he bought a batch of electronic surplus. Out of that came one of the first successful kits, a small oscilloscope ...
Prechilled acetone (acetone: sample volume = 6:1) was added to each tube before 4 h of precipitation at –20 °C and 20 min of centrifugation at 10,000g. Subsequently, 100 mM TEAB (100 µL) was added to dissolve the precipitate. This was followed by the addition of trypsin at an...

Briefly, uniformly sized tubers without defects were washed, peeled, diced into 0.5-cm 897 Y.P. Hwang et al. / Nutrition Research 31 (2011) 896–906 cubes, and freeze dried. Freeze-dried tuber samples (0.5 g) were homogenized in 15-mL ethanol/water (85:15 vol/vol) using an Ultra ...
First, 1.0 mL of a 1.865 mM 1,10-phenanthroline solution and 2.0 mL of the sample were added to a screw-capped tube and mixed. Then, 1.0 mL of a FeSO4·7H2O solution (1.865 mM) was added to the mixture. The reaction was initiated by adding 1.0 mL of H2O2 (0.03%, v/v). After...
Effect of FXT-GNP Co-Treatment on the Cell Viability of HepG2 Cells The cell viability test of HepG2 cells was done in order to study the effect of FXT-GNP co-treatment on cell proliferation. HepG2 cells were seeded onto a 6-well plate at 5 × 105 cells/mL and incubated overnight...
