Sodium alginate decreases the permeability of intestinal mucus (2015)
Journal Article

In the small intestine the nature of the environment leads to a highly heterogeneous mucus layer primarily composed of the MUC2 mucin. We set out to investigate whether the soluble dietary fibre sodium alginate could alter the permeability of the muc... Read More about Sodium alginate decreases the permeability of intestinal mucus.

Ultracentrifuge Methods for the Analysis of Polysaccharides, Glycoconjugates, and Lignins (2015)
Book Chapter

Although like proteins, polysaccharides are synthesized by enzymes, unlike proteins there is no template. This means that they are polydisperse, do not generally have compact folded structures, and are often very large with greater nonideality behavi...

Biophysical analysis of a lethal laminin alpha-1 mutation reveals altered self-interaction (2015)
Journal Article

Laminins are key basement membrane molecules that influence several biological activities and are linked to a number of diseases. They are secreted as heterotrimeric proteins consisting of one ?, one ?, and one ? chain, followed by their assembly int...

Recent advances in the analysis of macromolecular interactions using the matrix-free method of sedimentation in the analytical ultracentrifuge (2015)
Journal Article

Sedimentation in the analytical ultracentrifuge is a matrix free solution technique with no immobilisation, columns, or membranes required and can be used to study self-association and complex or “hetero”-interactions, stoichiometry, reversibility an...
