Analysis of Peptides using Asymmetrical Flow Field-flow Fractionation (AF4)

Journal of Pharmaceutical Sciences, 2021
While asymmetrical flow field-flow fractionation (AF4) has been widely used for separation of high molecular weight species and even particles, its ability to resolve lower molecular weight species has rarely been explored. Over the course of many projects, we have discovered that AF4 can be an effective analytical method for separating peptides from ...

Miniaturization of Frit Inlet Asymmetrical Flow Field-Flow Fractionation

Analytical Chemistry, 2004
A miniaturized frit inlet asymmetrical flow field-flow fractionation (mFI-AFlFFF) channel has been constructed and tested for the separation of proteins. By scaling down the geometrical channel dimension of a conventional FI-AFlFFF system, flow rate ranges that can be manipulated were decreased to 20-30 microL/min, which reduces the injection amount of

Asymmetric Flow Field-Flow Fractionation Investigation of Magnetopolyplexes

Macromolecular Chemistry and Physics, 2015
Asymmetric flow field-flow fractionation (AF4) is an analytical separation technique capable of providing information on different parameters of complex systems in a single measurement. Although it shows promise to be an important tool in the field of gene therapy, AF4 has only occasionally been used to study gene delivery vectors such as polyplexes ...

Fractionation of Humic Substances by Asymmetrical Flow Field-Flow Fractionation

Chromatographia, 2005
Asymmetrical flow field-flow fractionation was used to investigate the effects of pH and ionic strength of the buffer, and the binding of polyaromatic hydrocarbons (PAHs) on the particle sizes of humic substances (HSs). Particle sizes were greater when HSs were present in acidic medium with phosphate buffer than when they were present in alkaline ...

Distinguishing nanoparticle drug release mechanisms by asymmetric flow field–flow fractionation

Journal of Controlled Release, 2022
This research demonstrates the development, application, and mechanistic value of a multi-detector asymmetric flow field-flow fractionation (AF4) approach to acquire size-resolved drug loading and release profiles from polymeric nanoparticles (NPs). AF4 was hyphenated with multiple online detectors, including dynamic and multi-angle light scattering ...

Asymmetric Flow Field-Flow Fractionation in the Field of Nanomedicine

Analytical Chemistry, 2014
Asymmetric flow field-flow fractionation (AF4) is a widely used and versatile technique in the family of field-flow fractionations, indicated by a rapidly increasing number of publications. It represents a gentle separation and characterization method, where nonspecific interactions are reduced to a minimum, allows a broad separation range from several
