This can help remove concentrating too much on yourself and can make you look less disturbed and upset.
After centrifugation, the supernatant was removed and concentrated by 1/3 under a gentle flow of nitrogen gas (final concentration ~50 50, MeOH H2O).
The upper hexane layer was removed and concentrated under liquid nitrogen gas, and the residue was re-dissolved in 200 μL hexane, subsequently subjected to GC-MS analysis.
Non-biotinylated proteins in the supernatants were removed and concentrated by spin filtration using columns with 30 kDa molecular weight cutoff (Millipore).
The lysates were centrifuged and the supernatants were removed and concentrated 10-fold by using Centricon ultrafiltration tube (Millipore).The expression of E2 and E2-W529/A E2-W529/Ased wash goassessedE2 polyclonal antibodies (Biodesign International) using withern blottingoat
After centrifugation (Forma Scientific), a 10 mL aliquot was removed and concentrated to 1 mL.
In the final partitioning with butanol, the lower water layer was removed and concentrated under reduced pressure.
The upper layer consisting of n-hexane was removed and concentrated in a rotary evaporator to obtain n-hexane extract (HPA).
Sulfur trioxide in the exhaust gas of an internal combustion engine is removed and concentrated by absorption in a solution of 80% isopropyl alcohol, which quantitatively absorbs it and inhibits the oxidation of any sulfur dioxide which may be absorbed.
