Solution conformation and flexibility of capsular polysaccharides from Neisseria meningitidis and glycoconjugates with the tetanus toxoid protein (2016)
Journal Article
The structural integrity of meningococcal native, micro-fluidized and activated capsular polysaccharides and their glycoconjugates – in the form most relevant to their potential use as vaccines (dilute solution) - have been investigated with respect... Read More about Solution conformation and flexibility of capsular polysaccharides from Neisseria meningitidis and glycoconjugates with the tetanus toxoid protein.
Both reversible self-association and structural changes underpin molecular viscoelasticity of mAb solutions (2016)
Journal Article
The role of antibody structure (conformation) in solution rheology is probed. It is demonstrated here that pH-dependent changes in the tertiary structure of 2 mAb solutions lead to viscoelasticity and not merely a shear viscosity (η) increase. Steady... Read More about Both reversible self-association and structural changes underpin molecular viscoelasticity of mAb solutions.
Genetic improvement of tomato by targeted control of fruit softening (2016)
Journal Article
Controlling the rate of softening to extend shelf life was a key target for researchers engineering genetically modified (GM) tomatoes in the 1990s, but only modest improvements were achieved. Hybrids grown nowadays contain 'non-ripening mutations' t... Read More about Genetic improvement of tomato by targeted control of fruit softening.
Application of novel analytical ultracentrifuge analysis to solutions of fungal mannans (2016)
Journal Article
Polysaccharides, the most abundant biopolymers, are required for a host of activities in lower organisms, animals, and plants. Their solution characterization is challenging due to their complex shape, heterogeneity, and size. Here, recently develope...

A novel analytical ultracentrifugation based approach to the low resolution structure of gum arabic (2016)
Journal Article
Under investigation are the structural properties of gum arabic, an industrially important biopolymer for use as a stabilizer or in drug delivery, using Analytical Ultracentrifugation—a well-established, matrix-free probe for macromolecular size and... Read More about A novel analytical ultracentrifugation based approach to the low resolution structure of gum arabic.
Purification of bacterial membrane sensor kinases and biophysical methods for determination of their ligand and inhibitor interactions (2016)
Journal Article
This article reviews current methods for the reliable heterologous overexpression in Escherichia coli and purification of milligram quantities of bacterial membrane sensor kinase (MSK) proteins belonging to the two-component signal transduction famil...

The chelation of colonic luminal iron by a unique sodium alginate for the improvement of gastrointestinal health (2016)
Journal Article
Scope Iron is an essential nutrient. However, in animal models, excess unabsorbed dietary iron residing within the colonic lumen has been shown to exacerbate inflammatory bowel disease and intestinal cancer. Therefore, the aims of this study were... Read More about The chelation of colonic luminal iron by a unique sodium alginate for the improvement of gastrointestinal health.
The effect of thermal processing in oil on the macromolecular integrity and acrylamide formation from starch of three potato cultivars organically fertilized (2016)
Journal Article
Starches from three organically produced cultivars of potato tuber (Lady Rosetta, Spunta and Voyager) have been studied in relation to (i) acrylamide production (ii) macromolecular integrity after frying with extra virgin olive oil, soybean oil and c...

Molecular weight analysis of starches: which technique? (2016)
Journal Article
A number of methods are available to researchers for estimating molecular weights (molar masses) and molecular weight distributions of starches ? or those in solution, using an appropriate solvent/solubilisation protocol. We outline the methods avail... Read More about Molecular weight analysis of starches: which technique?.
Aspects of the analytical ultracentrifuge determination of the molar mass distribution of polysaccharides (2016)
Book Chapter
Molar mass or ‘molecular weight’ is one of the most fundamental parameters describing a macromolecule. Because of their polydisperse nature, polysaccharides are usually described by distributions of molar mass. SEC-MALS (size exclusion chromatography...

A glycoconjugate of Haemophilus influenzae Type b capsular polysaccharide with tetanus toxoid protein: hydrodynamic properties mainly influenced by the carbohydrate (2016)
Journal Article
Three important physical properties which may affect the performance of glycoconjugate vaccines against serious disease are molar mass (molecular weight), heterogeneity (polydispersity), and conformational flexibility in solution. The dilute solution...
