Asymmetrical flow field-flow fractionation in purification of an enveloped bacteriophage ϕ6 [PDF]

Journal of Chromatography B, 2018
Basic and applied virus research requires specimens that are purified to high homogeneity. Thus, there is much interest in the efficient production and purification of viruses and their subassemblies. Advances in the production steps have shifted the bottle neck of the process to the purification. Nonetheless, the development of purification techniques

Asymmetrical Flow Field-Flow Fractionation for Sizing of Gold Nanoparticles in Suspension [PDF]

Journal of Visualized Experiments, 2020
Particle size is arguably the most important physico-chemical parameter associated with the notion of a nanoparticle. Precise knowledge of the size and size distribution of nanoparticles is of utmost importance for various applications. The size range is also important, as it defines the most "active" component of a nanoparticle dose. Asymmetrical Flow

Quality control and purification of ready-to-use conjugated gold nanoparticles to ensure effectiveness in biosensing

Frontiers in Sensors, 2022
Introduction: Gold nanoparticles (AuNPs) and their conjugates are used for many applications in the field of sensors. Literature lacks procedures able to separate, purify and characterize these species in native conditions without altering them while ...

First Evidence of Acyl-Hydrolase/Lipase Activity From Human Probiotic Bacteria: Lactobacillus rhamnosus GG and Bifidobacterium longum NCC 2705

Frontiers in Microbiology, 2020
Lactobacillus rhamnosus GG (ATCC 53103) and Bifidobacterium longum NCC 2705 are among the most studied probiotics. However, the first evidence of acyl hydrolase/lipase of two annotated proteins, one in each genome of these strains, is reported in this ...

Phosphatidylinositol Stabilizes Fluid-Phase Liposomes Loaded with a Melphalan Lipophilic Prodrug

Pharmaceutics, 2021
Previously, a liposomal formulation of a chemotherapeutic agent melphalan (Mlph) incorporated in a fluid lipid bilayer of natural phospholipids in the form of dioleoylglyceride ester (MlphDG) was developed and the antitumor effect was confirmed in mouse ...

Marine Exopolysaccharide Complexed With Scandium Aimed as Theranostic Agents

Molecules, 2021
(1) Background: Exopolysaccharide (EPS) derivatives, produced by Alteromonas infernus bacterium, showed anti-metastatic properties. They may represent a new class of ligands to be combined with theranostic radionuclides, such as 47Sc/44Sc.
