Several feature selection methods that address this step are concentrated on statistical associations among descriptors and target properties, whereas the chemical knowledge is left out of the analysis.
The very highly diluted aqueous media obtained after the bubbling step were concentrated by solid-phase extraction (SPE) on hydrophobic cartridges and analysed on-line by reversed-phase HPLC with UV and fluorimetric detections.
Eluates from the last purification step were concentrated and resolved on SDS-PAGE.
eEF1A and eEF2 eluted from the gel filtration step were concentrated to 9.6 and 3.7 μM, respectively, snap frozen in liquid nitrogen, and stored at −80°C.
The flow-through from this step was concentrated and loaded onto a Superdex 200 10/300 (GE Healthcare, Pittsburgh, PA) gel filtration column in the buffer 20 mM HEPES pH 8.0, 150 mM KCl, 5 mM DTT, 1 mM EDTA, 0.2% DM.
Membranes at the interfaces of sucrose steps were concentrated by re-centrifugation at 100,000 g onto a saturated sucrose cushion in a new tube.
In the first MD step seawater is concentrated up to the saturation point of CaCO3.
Everything is concentrated there".
The market is concentrated, too.
This wealth is concentrated.
