Separation of specific single-enantiomer single-wall carbon nanotubes in the large-diameter regime [PDF]

open access: yes, 2019
The enantiomer-level isolation of single-walled carbon nanotubes (SWCNTs) in high concentration and with high purity for nanotubes greater than 1.1 nm in diameter is demonstrated using a two-stage aqueous two-phase extraction (ATPE) technique.

A centrifugation-based physicochemical characterization method for the interaction between proteins and nanoparticles

open access: yesNature Communications, 2016
Thein vivobehaviour of nanoparticles is influenced by the presence of the protein corona. Here, the authors use analytical ultracentrifugation to study the interaction of gold nanoparticles with bovine serum albumin, to gain insight into the corona ...

Quantitation of serum lipoproteins by electrophoresis on agarose gel: standardization in lipoprotein concentration units (mg/100 ml) by comparison with analytical ultracentrifugation

open access: yesJournal of Lipid Research, 1971
Lipoprotein electrophoresis on agarose gel has been modified to allow estimation of the absolute quantity of each fraction. The reproducibility of the method is illustrated by 12 determinations in a single day on serum from one normal subject: mean total

Nanoscale Structure Determination of Murray Valley Encephalitis and Powassan Virus Non-Coding RNAs

open access: yesViruses, 2020
Viral infections are responsible for numerous deaths worldwide. Flaviviruses, which contain RNA as their genetic material, are one of the most pathogenic families of viruses. There is an increasing amount of evidence suggesting that their 5’ and 3&#

Characterization of the Interaction between the Herpes Simplex Virus Type I Fc Receptor and Immunoglobulin G [PDF]

open access: yes, 1999
Herpes simplex virus type I (HSV-1) virions and HSV-1-infected cells bind to human immunoglobulin G (hIgG) via its Fc region. A complex of two surface glycoproteins encoded by HSV-1, gE and gI, is responsible for Fc binding.

Biophysical characterization of the outer membrane polysaccharide export protein and the polysaccharide co-polymerase protein from Xanthomonas campestris [PDF]

open access: yes, 2014
This study investigated the structural and biophysical characteristics of GumB and GumC, two Xanthomonas campestris membrane proteins that are involved in xanthan biosynthesis. Xanthan is an exopolysaccharide that is thought to be a virulence factor that

A Dimerization Site at SCR-17/18 in Factor H Clarifies a New Mechanism for Complement Regulatory Control

open access: yesFrontiers in Immunology, 2021
Complement Factor H (CFH), with 20 short complement regulator (SCR) domains, regulates the alternative pathway of complement in part through the interaction of its C-terminal SCR-19 and SCR-20 domains with host cell-bound C3b and anionic oligosaccharides.

A non-classical view on calcium oxalate precipitation and the role of citrate

open access: yesNature Communications, 2017
The formation mechanism of abundant calcium oxalate biomaterials is unresolved. Here the authors show the early stages of calcium oxalate formation in pure and citrate-bearing solutions by using a titration set-up in conjunction with solution quenching ...

Formation of Nanoclusters in Gold Nucleation

open access: yesCrystals, 2020
Gold nanoclusters consisting of a specific atom number have gained popularity in research in recent years due to their outstanding properties. Due to their molecule-like behavior, their properties depend strongly on their size.

Oligomeric States and Hydrodynamic Properties of Lysyl Oxidase-Like 2

open access: yesBiomolecules, 2021
Lysyl oxidase-like 2 (LOXL2) has emerged as a promising therapeutic target against metastatic/invasive tumors and organ and tissue fibrosis. LOXL2 catalyzes the oxidative deamination of lysine and hydroxylysine residues in extracellular matrix (ECM ...
