Sep 04, 2012 · The DGT devices with a 0.4 mm resin gel layer, a 0.8 mm diffusive gel layer and a 0.45 μm pore-size filter, were deployed at a 0.20–0.25 m water depth to avoid turbulent flow zones. After 15 days, DGT samplers were retrieved and kept humid at 4 °C until the analysis.
The concentrated samples were reconstituted with 80% methanol (5 mL) and filtered through a 0.22μm membrane syringe filter (CHOICE 13 mm, PTFE, Thermo Scientific, Waltham, MA, USA).
Results To no-carrier-added Na123I (0.5 mCi in 0.1 % aqueous NaOH) in a 2 mL Wheaton vial was added tin precursor 4 ( 100 µL of 4.8 X 10-2 M solution in H2O:THF=1:1). Peracetic acid (100 µL; 0.3 % THF solution) was added and the resulting mixure was stirred for 10 min at rt.
Oct 01, 2019 · Any non-entrapped drug was removed by filtration through a 0.22μm syringe filter (Millex-LG, Millipore Co., USA) and the drug loaded micelles were lyophilized and stored at 4℃ before use. To prepare PTX-loaded control micelles, mPEG2k-PDLLA2k (MPP) and PTX (6:1, w/w) were dissolved in 5 mL acetone, and the solvent was subsequently evaporated
Dec 01, 2019 · Three sample groups were used for all experiments. The samples, obtained after a given interval, were filtered through 0.22μm syringe filters. Then, the concentrations of nitrate and nitrite in the filtrates were determined using ion chromatography (Dionex ICS-1000 system).

FIG. 23: shows an example chromatography trace of Strep trap (GE Healthcare) purification of CsgG protein (x-axis label=elution volume (mL), Y-axis label=Absorbance (mAu)). The sample was loaded in 25 mM Tris, 150 mM NaCl, 2 mM EDTA, 0.01% DDM and eluted with 10 mM desthiobiotin. The elution peak in which CsgG protein eluted is labelled as E1.
