After vigorous mixing and phase separation by centrifugation, the upper aqueous layer was removed and discarded.
After vigorous mixing and phase separation, the top organic layer (blue, if oseltamivir was present) was transferred to a 13-mm diameter clean glass tube for absorbance measurements at 590 nm.
After cooling down, addition of 1 ml of n-butyl alcohol, vigorous vortex-mixing and phase separation at 1000 g for 5 min, the absorbance was measured in the upper phase at 530 nm.
Then 15% (0.05 M) aqueous Fe3+ malic acid chelate solution was added drop wise to the oil phase under vigorous stirring in order to prepare optically clear and stable system.
Rhodococcus equi was grown at 37°C to a late log phase under vigorous shaking (OD600 approximately 1.0, 50 ml of broth).
Yeast hydrophobicity was measured by assaying the partitioning of yeast cells between an aqueous and hydrophobic hydrocarbon phase after vigorous mixing (Rosenberg 2006).
Physical activity was assessed by the answers to questions on the frequency and duration of participation in moderate or vigorous physical activity at phase 3.
Only haploid plant G, obtained directly from embryo germination without a callus phase, displayed vigorous growth and was the only haploid clementine plant to produce flowers.
Methyl-hyroxybutyryl monomers were extracted after addition of water (20% v/v) and vigorous mixing, The organic phase was analyzed by GC-FID with a DB-WAX column, length 15 m, I.D. 0.32 mm, film 0.5 μm.
