LCGC North America Application Note Alert Having trouble viewing this email? Click here Sizing of Polydisperse Silver Nanoparticle Suspensions A comparison of DLS in batch mode with AF4 coupled with DLS for the measurement of a mixture of silver nanoparticles of different sizes is presented. Miniaturized AF4 for the Fast Separation of Nanoparticle Mixtures This note discusses how to significantly reduce analysis times in asymmetrical flow field-flow fractionation (AF4) using a miniaturized fractionation cartridge. Characterization of Tau Protein Aggregates with AF4 and UV-MALS-DLS The characterization of tau protein and its fibril aggregates is important in the understanding of Alzheimer's disease, and is the focus of this study. Measurement of Cancer Biomarker Enrichment in Exosomes In this study the goal was to characterize the MCF-7 tumour exosome by size using AF4 coupled to MALS, and by mass using centrifugal field-flow fractionation (CF3). Quantification of Liposome-Encapsulated Drug Using CF3 Centrifugal field-flow fractionation (CF3) was used to separate free drug from liposomes and drug-containing liposomes in order to quantify the free drug. Purification of Protein Solutions Using Continuous SPLITT Fractionation System This application note presents a new purification technique based on diffusion to purify a bovine ϒ-globulin solution with high throughput and efficiency. Absolute Molar Mass of Proteins and Antibodies with ÄKTA-MALS ÄKTA systems are used for the purification, separation, and characterization of proteins and antibodies in the pharmaceutical area and in biomolecular research. Thermal FFF with MALS and Viscometer Thermal field-flow fractionation (TF3) is one of the preferred methods to determine the molecular weight and molecular weight distribution of large polymer samples.
