Cholesteric Liquid Crystalline

We found that cellulosic liquid-crystalline films displayed not only a wide-ranging colour change but also inversion of circular dichroism upon a mechanical stimulus.

Circular Dichroïsm

Specifically designed cuvette holders enable the artefact-free measurement of circular dichroism of thin layer and volatile anisotropic solutions by averaging of 4 sample orientations. The setup further allows for the insertion of permanent magnets.

Urinary Glycoprotein

Much work has been reported on the chemical, physical and morphological properties of urinary Tamm-Horsfall glycoprotein (THG). Although it was once reported that cystic fibrotic (CF) individuals had a defective THG, more recent data indicate that THG and CF-THG are similar if not identical.No studies on the conformational aspects have been reported on this glycoprotein using circular dichroism (CD). We examined the secondary structure of THG and derivatives under various conditions and have correlated these results with quaternary structure using electron microscopy.THG was prepared from normal adult males and CF-THG from a 16-year old CF female by the method of Tamm and Horsfall. CF female by the method of Tamm and Horsfall.
