These limitations have contributed to an increased usage of ultrafiltration methods to concentrate aquatic viruses, such as vortex flow filtration (VFF) (Paul et al., 1991) and subsequently tangential flow filtration (TFF) (Wommack et al., 2010).
Since the publication of this method, most ultrafiltration applications have used some or all of the characteristics of pulsed ultrafiltration, very often without identifying them as such.
Despite its high expression quantity, the activity of the product was restrained; therefore, the enzyme was purified using a series of methods, including ultrafiltration and Ni2+-affinity chromatography, to relieve the inhibition of the culture medium [ 27].
Moreover, the saline-flush method has significant drawbacks such as the limitation of ultrafiltration because of fluid load and the requirement for intensive nursing supervision.
Rotavirus particles were isolated from 25 g food samples by a simple method including ultrafiltration, originally designed for the detection of norovirus in various food matrices.
However, with this method we found no evidence of peptide accumulation for most of the other transgenic lines, regardless of type of ultrafiltration device used (Additional file 2).
Based on the results of the method comparison, the dissolved fraction of the other ENP suspensions included in this study was determined by means of ultrafiltration, as described above.
Based on the results of ultrafiltration, the present study discusses the effect of colloids on groundwater chemistry and proposes technical methods for quality-controlled groundwater and colloid sampling.
Tissue ultrafiltration (TUF) is a method of reducing tissue edema by removal of interstitial fluid.
We use ultrafiltration which is a method of choice to recycle silica (SiO2 -based SiO2 -based
