LDH levels were calculated from t = 20 min minus t = 5 min, subtracting the background readings recorded during the same time period.
Using experimental data of protein half-lives in yeast (Belle et al. 2006), we found that the downregulated proteins exhibited a shorter protein half-life (median = 41 min) than the background (median = 45 min) (one-sided Wilcoxon rank-sum test, P = 0.01; fig. 3 B).
A test session began by placing a mouse in a plastic cylinder in a sound-attenuated chamber and leaving it undisturbed for 10 min. The background white noise level in the chamber was 65 dB.
Data shown here are from recordings taken at least 20 min after the background light was switched on to allow for cone light adaptation.
The rats were killed at the end of the experimental protocol using an overdose of anaesthetic, and 30 min later, the background noise was recorded.
Any error in the calibration process once the lithium bolus is injected will result in a delay of approximately 15 min while the background plasma lithium concentration subsides.
Briefly, the endogenous peroxidase was inactivated with hydrogen peroxide (0.3% in methanol/PBS for 30 min), and the background was blocked with 5% normal goat serum (NGS) and 1% bovine serum albumin (BSA) in 0.5% Triton X-100.
The input pixel should have brightness less than at least #min samples in the background model and the same samples should be at a color distance less than a threshold with the input pixel.
Unspecific liver uptake decreased from 5.2%ID/g to 2.1%ID/g over 90 min similar to the background radioactivity in the feces and gall bladder (Table 2), which is believed to be a beneficial effect of the increased polarity of this novel radiofolate.
The permeabilized cells were then incubated with a blocking solution (PBS containing 0.1% Triton X-100 and 5 mg/ml of bovine albumin) for 20 min to minimize the background staining.
