Following overnight incubation, rotating in the dark, the beads were loaded into a disposable column and washed with 2 mL each of water, 5 M NaCl, 50% (v/v) acetonitrile, and 5% (v/v) formic acid in water.
For PsVs labelling with a fluorochrome that is only activated after cell entry [ 43], 20 μg of purified PsVs were mixed with 200 μM Oregon Green®488 carboxylic acid diacetate succinimidyl ester (Molecular Probes) in a final volume of 500 μl HSB (pH 7.5) and incubated for 24 h at room temperature in the dark rotating.
It is widely believed that the matter we are made of, atomic nuclei, is only a small fraction of the total matter in the universe and that our Milky Way Galaxy contains a large amount of weakly interacting, non-rotating dark matter.
And, he added, real-time cosmology could help find answers to the most basic but important questions about the cosmos, such as whether or not the universe is rotating, the nature of dark energy and the masses of large-scale structures in the universe.
Root tips were incubated on a rotating platform in the dark for 30 min, and subsequently washed 3 times in 50 mM Tris, pH 7.5, to remove residual H2DCFDA that would otherwise increase background fluorescence.
However, if the illumination is the polarized light and the polarization is rotated, a clear dark region appears along the polarization direction.
As watchmen shifts rotated in the dark, someone unrolled a mattress on a bench and told me to go sleep.
If, as many physicists believe, our galaxy is rotating through a stationary region of dark matter, then the dark matter should strike the atoms in Sciolla's detector like rain hitting the windshield of a moving car.
Activity of the positively identified VA PCs was subsequently recorded during vestibular stimulation by rotating the turntable in the dark at frequency of 0.6 Hz and amplitude of 5 degrees.
The form is circular, and the spiralling ramp that ascends it broken by a bulging bay on each floor creates a rotating band of light and dark, of solid and void, that terminates in the opaque, almost flat wired-glass dome.
