Purification of Fibrillin-Containing Microfibrils and Collagen VI Microfibrils by Density Gradient Centrifugation

Analytical Biochemistry, 1998
A method is described for the purification of collagen VI microfibrils and fibrillin-containing microfibrils, respectively. High M(r) microfibril-rich preparations isolated from nuchal ligament by bacterial collagenase digestion and size fractionation were purified by CsCl density gradient centrifugation.

Phase transitions in cellulose microfibril dispersions by high-energy mechanical deagglomeration.

Langmuir, 2014
It is shown that dispersions of cellulose microfibrils display gel-sol and direct gel-colloidal liquid crystalline structure transitions. This is achieved by applying high-energy mechanical deagglomeration to bacterial cellulose (BC) networks in the ...

Extraction of bamboo microfibrils and development of biocomposites based on polyhydroxybutyrate and bamboo microfibrils

Journal of Composite Materials, 2010
This investigation deals with the detailed procedure for the extraction of microfibrils from raw bamboo. The microfibrils obtained from raw bamboo were characterized using scanning electron microscope and the average diameter of the fibrils was found to be 10 μm.

Cellulose microfibril twist, mechanics, and implication for cellulose biosynthesis.

Journal of Physical Chemistry A, 2013
All-atom molecular dynamics simulations with explicit water solvent were used to investigate the microstructure and conformational dynamics of cellulose Iβ microfibrils as a function of microfibril length and cross-sectional size and shape.

Comparison of Rhapidosomes and Asbestos Microfibrils

Science, 1978
Rhapidosomes (cylindrical nucleoprotein rods of bacterial origin) show great structural similarity to the microfibrils of chrysotile asbestos when negatively stained and observed with the electron microscope. If the negative stain is omitted, the asbestos retains its structural detail whereas the rhapidosomes appear to be unstructured bodies.

Antibacterial hybrid materials fabricated by nanocoating of microfibril bundles of cellulose substance with titania/chitosan/silver-nanoparticle composite films.

Journal of materials chemistry. B, 2013
Uniform ultrathin titania/chitosan composite films were coated on the cellulose microfibril bundles of natural cellulose substance (common commercial filter paper) by a layer-by-layer self-assembly process.

Immunolocalization of microfibril and microfibril-associated proteins in the subendothelial matrix of the developing mouse aorta

Journal of Cell Science, 1994
ABSTRACT In the developing aorta, endothelial cell connecting filaments extend from the abluminal surface of the endothelial cell to the subjacent elastic lamina. The connecting filaments are in alignment with intracellular stress fibers and are oriented parallel to the direction of blood flow.

The maize primary cell wall microfibril: a new model derived from direct visualization.

Journal of Agricultural and Food Chemistry, 2006
Understanding the molecular architecture of the plant cell wall is critical to reducing the biomass recalcitrance problem, which currently impedes economic bioconversion processing. The parenchyma cell walls from field senesced, maize stem pith have been

The Supramolecular Organization of Collagen VI Microfibrils

Journal of Molecular Biology, 2003
Collagen VI has a ubiquitous distribution throughout connective tissues, and has key roles in linking cells and matrix macromolecules. We have generated three-dimensional reconstructions of collagen VI microfibrils using automated electron tomography (AET) in order to obtain new insights into the organisation of collagen VI in assembled microfibrils ...
