After diethyl ether was evaporated, the lipids were rehydrated in ND buffer (20 mM HEPES, 150 mM NaCl and 30 mM DDM) at a concentration of 10 mM. Purified protein was mixed with lipids and incubated for 30 min, after which the purified MSP was added and incubated for 30...
We investigated the effect of various mixtures of diethylether, halothane, nitrous oxide and oxygen on the intracellular LMWI content and mitochondrial function of the rat myocardium. 展开 关键词: Nitrous oxide halothane oxygen radicals mitochondria iron diethylether ...
The molecular weight of the active material was found to be less than that of vitamin B12 (1330 mol wt) on the basis of gel filtration on Sephadex G-25. The low molecular weight colony-stimulating activity (LMW-CSA) was trypsin-sensitive, and extractable into chloroform or diethyl ether. ...
(TFA), 2.5% H2O, 2.5% triisopropylsilane). After 2 h, the resin was removed by filtration, and the peptide precipitated with diethyl ether on ice. The peptide was isolated by centrifugation, then dissolved in water and freeze-dried overnight. Portions of the peptide were purified on a ...

The pentafluorobenzyl esters were eluted with 7 ml ofn-hexane/diethyl ether (2:1), evaporated, dissolved in 100 μl of acetonitrile, and analyzed by GC-MS. GC-MS The following parameters were used for GC-MS: GCQ Finnigan, 70 eV, NCI, ionization gas NH3, source temperature 140 °C, ...
. Small molecular weight proteins present in the microalbuminuria samples likely behaved in a similar manner as degraded albumin, investigated above, resulting in red-shifting behavior. Since the sensor responded to these samples with a net red shift, we conclude that the red shift from other ...
Here we report that the tri-1-adamantylphosphine-nickel complex [Ad3PNiBr3]-[Ad3PH]+ upon activation with an alkylaluminoxane catalyzes the polymerization of ethylene to ultrahigh-molecular-weight, nearly linear polyethylene (Mn up to 1.68 × 106 g mol−1) with initial activities ...
The sodium hydroxide portion was saturated with solid carbon dioxide pellets and extracted with diethyl ether (3×30 cm3). The extracts were evaporated under reduced pressure to give a crude oil. The oil was chromatographed (SiO2, heptane:ethyl acetate, 1:1) to give the phenol, (0.14 g, ...
