Asymmetrical flow field-flow fractionation for the analysis of PEG-asparaginase

Talanta, 2016
Monomethoxypolyethylene glycol L-asparaginase (PEG-ASNASE) is the PEGylated version of the enzyme L-asparaginase (ASNASE). Both are used for remission induction in acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL). The treatment control is generally carried out by performing activity assays, though methods to determine the actual ...

Optimisation of asymmetrical flow field flow fractionation for environmental nanoparticles separation

Journal of Chromatography A, 2008
The fractionation of natural nanoparticles by Asymmetrical Flow Field Flow Fractionation (As-Fl-FFF) was optimised by considering the following operating conditions: ionic strength, surfactant concentration and crossflow rate. The method performances such as fractionation recovery and fractionation efficiency were evaluated on a stable solution of ...

Cytochrome c?dimyristoylphosphatidylglycerol interactions studied by asymmetrical flow field-flow fractionation

Analytical and Bioanalytical Chemistry, 2004
Lipid membranes are well recognized ligands that bind peripheral and integral proteins in a specific manner and regulate their function. Cytochrome c (cyt c) is one of the partner peripheral protein that binds to the lipid membranes via electrostatic and hydrophobic interactions.

Asymmetric-channel flow field-flow fractionation with exponential force-field programming

Journal of Chromatography A, 1992
Abstract Equipment and techniques have been developed to program the crossed-flow force fields with parallel-plate, asymmetric channels in flow field-flow fractionation (F1FFF). Force-field programming permits the rapid separation of samples with a wide range of molecular sizes; resolution is easily varied. Detectability of late-eluting components is

Optimization of asymmetrical flow field-flow fractionation (AF4)

LC GC Europe, 2010
Asymmetrical flow field-flow fractionation (AF4) can be used on a routine basis to separate high-molecular-weight compounds as an alternative to size-exclusion chromatography (SEC), but the principle of separation is very different and a different approach is required for optimization.

Stopless Flow Injection in Asymmetrical Flow Field-Flow Fractionation Using a Frit Inlet

Analytical Chemistry, 1997
Stopless flow operation of asymmetrical flow field-flow fractionation (FFF) has been achieved by introducing a hydrodynamic relaxation method using a frit inlet. By using frit inlet injection, a focusing process which has been an essential part of runs at the asymmetrical flow FFF system can be completely avoided.

Retention ratio and nonequilibrium bandspreading in asymmetrical flow field-flow fractionation

Analytical and Bioanalytical Chemistry, 2015
In asymmetrical flow field-flow fractionation (As-FlFFF), only the membrane-covered accumulation wall is permeable to fluid; the opposite channel wall is impermeable. Fluid enters the channel at the inlet and exits partly through the membrane-covered accumulation wall and partly through the channel outlet.

Field-Flow Fractionation with Asymmetrical Electroosmotic Flow. II. Charged Particles

Journal of Liquid Chromatography & Related Technologies, 1997
The study of field-flow fractionation (FFF) with asymmetrical electroosmotically driven flow is extended to the case of charged sample particles. In this case, field-flow fractionation is combined with capillary zone electrophoresis in the same flat FFF channel.
