A rapid reverse phase evaporation method for the reconstitution of uncharged thylakoid membrane lipids that resist hydration.
Comparison of several lipid reconstitution methods showed that they were not equally efficient at transferring the predominant thylakoid lipid, monogalactosyldiglyceride (MG), to the aqueous phase. We report a reverse phase evaporation method that employs Freon 11 as a lipid solvent and is capable of successfully hydrating MG in spinach (Spinacia oleracea L.) at room temperature within minutes....
متن کاملPreparation of Nonionic Vesicles Using the Supercritical Carbon Dioxide Reverse Phase Evaporation Method and Analysis of Their Solution Properties.
We have previously reported a new preparation method for liposomes using supercritical carbon dioxide (scCO2) as a solvent, referred to as the supercritical carbon dioxide reverse phase evaporation (scRPE) method. In our previous work, addition of ethanol to scCO2 as a co-solvent was needed, because lipid molecules had to be dissolved in scCO2 to form liposomes. In this new study, niosomes (non...

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Tightly Bound Magnesium in Mitochondrial Adenosine Triphosphatase from Beef Heart*
Tightly bound magnesium was found in soluble, purified ATPase (F,) from beef heart mitochondria in the amount of 1 mol/mol of F1. Iron, zinc, cobalt, manganese, calcium, sodium, copper, and potassium were not tightly bound at stoichiometric levels. Removal of magnesium by chelating agents caused loss of ATPase activity. Removal of tightly bound nucleotide by gel filtration in 50% glycerolor 60 ...
