LIGHT SCATTERING STUDIES ON INSULIN

Light Scattering Studies on Lecithin Micellar Solutions

Light scattering studies on DNA condensation.

DNA condenses into compact particles when mixed with dilute solutions of trivalent cations such as spermidine or hexammine cobalt (111) (CoHex) [ 1-41. These particles are approximately the size of bacteriophage capsids and generally have a toroidal or rodlike morphology. Remarkably, the size of the condensed particles is quite insensitive to the size of the DNA [3, 51. Particles formed with T7...

Angular Light-scattering Studies on Isolated Mitochondria

Angular light-scattering studies have been carried out on suspensions of isolated rat liver mitochondria. The angular scatter pattern has a large forward component, typical of large particles. Changes in dissymmetry and in the intensity of light scattered at 90 degrees have been correlated with changes in optical density during the course of mitochondrial swelling and contraction. Such changes ...

Effect of tocopherol on Pluronic microemulsions: turbidity studies and Dynamic light scattering and dynamic surface tension measurements

The development and design of the biocompatible and biodegradable thermodynamically stable micellar and microemulsion transparent dispersions to reduce the free and unbounded drugs concentration in the blood is a basic challenge in field of drug efficacy and bioavailability of drugs. In the current work, solubilization capacity of the drug (Tocopherol), oil (Ethyl Butyrate), and oil+drug (1:1 m...

Static Light Scattering Studies on Xanthan in Aqueous Solutions

A commercial sample of xanthan was (i) sonicated and fractionated by GPC on Sepharose Cl-2B with 0.1 M NaCl as eluant/solvent. The angular dependence of scattered light was measured (offline) and interpreted in terms of the wormlike chain model using the “master curve procedure”. The persistence length was estimated as LP≈ 150 nm. The mass per unit lengthML≈ 2000 g/mol·nm indicates double-stran...
