Dynamics of structural changes in biological particles from rapid light scattering measurements
Abstract:
A unique light scattering photometer has been developed for continuous measurement of the complete angular spectrum of light scattered by dynamically changing systems. Although primarily designed for work with biological particles such as large viruses, subcellular organelles, and bacteria, it can be used to study polymerization and depolymerization of macromolecules, synthetic polymers, etc. The instrument has been applied to the direct measurement of the diameter of phospholipid vesicles and micelles in chromatographic column effluents and to the dynamics of polymerization of microtubular protein and osmotic lysis of chromaffin of granules.

01:19Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
01:10X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
