Solution conformation and flexibility of capsular polysaccharides from Neisseria meningitidis and glycoconjugates with the tetanus toxoid protein (2016)
Journal Article
Abdelhameed, A. S., Morris, G. A., Almutairi, F., Adams, G. G., Duvivier, P., Conrath, K., & Harding, S. E. (in press). Solution conformation and flexibility of capsular polysaccharides from Neisseria meningitidis and glycoconjugates with the tetanus toxoid protein. Scientific Reports, 6(1), 1-11. https://doi.org/10.1038/srep35588

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...

Both reversible self-association and structural changes underpin molecular viscoelasticity of mAb solutions (2016)
Journal Article
Sarangapani, P. S., Weaver, J., Parupudi, A., Besong, T. M., Adams, G. G., Harding, S. E., …Pathak, J. A. (2016). Both reversible self-association and structural changes underpin molecular viscoelasticity of mAb solutions. Journal of Pharmaceutical Sciences, 105(12), https://doi.org/10.1016/j.xphs.2016.08.020

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...

Genetic improvement of tomato by targeted control of fruit softening (2016)
Journal Article
Uluisik, S., Chapman, N. H., Smith, R., Poole, M., Adams, G., Gillis, R. B., …Seymour, G. B. (2016). Genetic improvement of tomato by targeted control of fruit softening. Nature Biotechnology, 34, 950-952. https://doi.org/10.1038/nbt.3602

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.

Molecular weight analysis of starches: which technique? (2016)
Journal Article
Harding, S. E., Adams, G. G., & Gillis, R. B. (2016). Molecular weight analysis of starches: which technique?. Starch/Stärke, 68(9-10), https://doi.org/10.1002/star.201600042

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
Harding, S. E., Adams, G. G., Gillis, R. B., Almutairi, F. M., & Morris, G. A. (2016). Aspects of the analytical ultracentrifuge determination of the molar mass distribution of polysaccharides. In S. Uchiyama, F. Arisaka, W. F. Stafford, & T. M. Laue (Eds.), Analytical ultracentrifugation: instrumentation, software and applications (375-386). Springer. https://doi.org/10.1007/978-4-431-55985-6_18

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
Abdelhameed, A. S., Adams, G. G., Morris, G. A., Almutairi, F. M., Duvivier, P., Conrath, K., & Harding, S. E. (2016). A glycoconjugate of Haemophilus influenzae Type b capsular polysaccharide with tetanus toxoid protein: hydrodynamic properties mainly influenced by the carbohydrate. Scientific Reports, 6(1), Article 22208. https://doi.org/10.1038/srep22208

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...
