For example, intrathoracic impedance decreases are monitored in the ambulatory setting as an indication of developing fluid overload.
Using transcriptome analysis, we observed that the two transcripts were abundant both in wild type U87 (U87wt) cells and in cells transfected with the empty vector (U87Ctrl cells), whereas ~100-fold (EREG) and 8-fold (HB-EGF) decreases were monitored in cells expressing an IRE1α dominant-negative protein (U87dn cells).
The decrease in absorbance was monitored using a UNICAM UV/VISIBLE Spectrophotometer, Helios Beta at 381 nm.
The reaction was initiated by the addition of 0.1 mM cytochrome C giving a final volume of 1 ml reaction mixture and decrease in absorbance was monitored for 3 min at 550 nm.
The decrease of H2O2 was monitored at 240 nm and quantified by its molar extinction coefficient (36 M−1 cm−1) and the results expressed as CAT units per mg of leaf fresh weight.
The decrease in absorbance was monitored at 240 nm (Spectramax 190, Molecular Devices, Sunnyvale, CA) for 25 reads (12 s interval, total measuring time: 4 min, 17 s).
TrxR assay was performed in 50 mM sodium phosphate, pH 7.0, 50 mM KCl, 1 mM EDTA, 100 µM Nm23-H1, 200 µM NADPH, 80 nM rat TrxR1, 50 µM Trx1 and the absorbance decrease of NADPH was monitored at 340 nm for 5 min by spectrophotometer [33], [34].
The decrease in A340 was monitored to assess the activity.
The S1 was withdrawn and the decrease in fluorescence was monitored.
The rate of the decrease in A340 was monitored using a Beckman Series 600 spectrophotometer.
