The influence of dolichol, dolichol esters, and dolichyl phosphate on phospholipid polymorphism and fluidity in model membranes.
The effect of dolichols, polyprenols, dolichol esterified with fatty acids, and dolichyl phosphate on the structure and fluidity of model membranes was studied using 31P NMR, small-angle x-rayExpand
Determination of low levels of total mercury in blood and plasma by cold vapour atomic fluorescence spectrometry.
A sensitive and semi-automated analytical method allowing determination of low and normal levels of total mercury in human blood and plasma using cold vapour atomic fluorescence is described. SamplesExpand
Transfer of secretory proteins from the endoplasmic reticulum to the Golgi apparatus: discrimination between homologous and heterologous transfer in intact heterokaryons.
To examine aspects of the transfer of secretory proteins from the endoplasmic reticulum to the Golgi apparatus in situ, heterokaryons were formed between Hep G2 human hepatoma cells and WI-38 humanExpand
Dolichyl phosphate induces non-bilayer structures, vesicle fusion and transbilayer movement of lipids: a model membrane study.
The effect of dolichol and dolichyl phosphate on fusion between large unilamellar vesicles comprised of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) andExpand
Esterification of dolichol in rat liver.
In the various subcellular fractions of rat liver 45-75% of the total dolichol was esterified with a fatty acid. The esterification reaction was localized exclusively in the microsomes, and theExpand
Compartmentalization of phosphatidylethanolamine in microsomal membranes from rat liver.
Microsomal membranes from rat liver were treated with the cross-linking reagent 1,5-difluoro-2,4-dinitrobenzene (DFDNB). Experimental work showed that at a probe concentration of 0.75 mM all freeExpand
Subcellular localization in normal and vitamin A-deficient rat liver of vitamin A serum transport proteins, albumin, ceruloplasmin and class I major histocompatibility antigens.
The subcellular localization in rat liver cells of retinol-binding protein (RBP), prealbumin, ceruloplasmin, albumin, and class I transplantation antigen chains was investigated by radioimmunoassayExpand
Transfer of phospholipids between the endoplasmic reticulum and mitochondria in rat hepatocytes in vivo.
Abstract The transfer of phospholipids from the endoplasmic reticulum to the inner mitochondrial membrane was investigated by pulse labeling in vivo . With [3H]glycerol microsomalExpand
Localization of phosphatidylethanolamine in microsomal membranes and regulation of its distribution by the fatty acid composition.
Rat liver microsomes were incubated with the monofunctional aminoreagent fluorescamine. Although the probe easily penetrated the membranes, two pools of phosphatidylethanolamine (PE) could beExpand
Phospholipid and enzyme arrangements of rat liver rough microsomal subfractions from control and methylcholanthrene-treated animals.
Rough microsomes from rat liver of both control and methylcholanthrene-treated animals were subfractionated on a discontinuous sucrose gradient into three fractions according the their sedimentationExpand
