The fraction of the lipid in a biological membrane that is in a fluid state: a spin label assay.

چکیده
The solubility of the spin label TEMPO (I) in membranes depends on the fluidity of the membrane. An empir ical relat ionship has been establ ished between TEMPO solubility and fluidity, measured by the order parameter S~o. This relationship is employed to determine the fract ion of the lipid in membranes of rabbit muscle sarcoplasmic re t iculum that is in a fluid state. We find that 84% of the lipid in this membrane is in a fluid state at 25 °C.

Lipid-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...

Scaffolds derived from decellularized tissues provide a natural microenvironment for cell culture. Embryonic cerebrospinal fluid (e-CSF) contains factors which play vital roles in development of the nervous system. This research was aimed to survey the effect of Wistar rat e-CSF on neural differentiation of bone marrow derived mesenchymal stem cells (BM-MSCs) cultured on the human amniotic memb...
متن کاملApplying a Modified Two-Fluid Model to Numerical Simulation of Two-Phase Flow in the Membrane Chlor-Alkali Cells
In this study, gas evolution in a vertical electrochemical cell is investigated numerically with a modified two-fluid model. The mathematical model involves solution of separate transport equation for the gas and liquid phases with an allowance to inter-phase transfer of mass and momentum. The governing equations are discreted via the finite volume technique and then are solved by ...
