Thermal lability of membrane proteins of age separated erythrocytes as studied by electron spin resonance spin label technique.
Thermal lability of bovine erythrocyte membrane proteins was studied by electron spin resonance using maleimide spin label. The temperature of the sample during measurements could be varied for the first time between 0 and 60 degrees C with an accuracy of +/- 0.1 degrees C. Our results show that "old" erythrocyte membrane proteins are less stable against thermal denaturation then "young" cells.
متن کاملMAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON
The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...
متن کاملSelectivity of interaction of phospholipids with bovine spinal cord myelin basic protein studied by spin-label electron spin resonance.
The selectivity of interaction between bovine spinal cord myelin basic protein (MBP) and eight different spin-labeled lipid species in complexes with dimyristoylphosphatidylglycerol (DMPG) and between spin-labeled phosphatidylglycerol and spin-labeled phosphatidylcholine in complexes of MBP with various mixtures of DMPG and dimyristoylphosphatidylcholine (DMPC) has been studied by electron spin...
متن کاملLipid-protein interactions in thylakoid membranes of chilling-resistant and -sensitive plants studied by spin label electron spin resonance spectroscopy.
Lipid-protein interactions in thylakoid membranes from lettuce, pea, tomato, and cucumber have been studied using spin-labeled analogues of the thylakoid membrane lipid components, monogalactosyl diglyceride and phosphatidylglycerol. The electron spin resonance spectra of the spin-labeled lipids all consist of two components, one corresponding to the fluid lipid environment in the membranes and...
متن کاملImmobilization-induced changes in erythrocyte membrane fluidity in rabbits: a spin-label electron spin resonance study.
It has been shown that many diseases are linked to abnormalities of the erythrocyte membrane. This study observed the changes in erythrocyte membrane fluidity during an immobilization period of 21 days. The right hindlimbs of male adult New Zealand white rabbits were immobilized for 21 days. Blood samples were collected and heparinized prior to immobilization and on days 1, 3, 7, 14, and 21 of ...
