Finally, sections were washed in distilled H2O and contrasted/embedded in aqueous uranyl 1%. Grids were examined in a Phillips Tecnai 12 transmission electron microscope (Philips Electron Optics, Holland) at 80 kV, from the facility of the Pontificia Universidad Católica de Chile. Finally, images...
A water-dispersible veterinary preparation comprises (a) up to 50% by weight of a therapeutically active substance, (b) from 2 to 70% by weight of a polyethyleneglycol which is solid at room temperature and (c) from 10 to 70% by weight of an amphiphilic agent which is solid at room ...
DNA was transfected into those cells by the Ca3(PO4)2 coprecipitation method with pSV-neo as a selectable marker. Individual clones were grown in the presence of G418 (800 μg/ml). Assessment of Mitochondrial Activity Mitochondrial activity was observed in living cells by measurement of ...
0.1 mol of calcium nitrate (Ca(NO3)2) and 0.1 mol of titanium sulfate (TiSO4) were dissolved in about 500 ml of water, followed by neutralizing with an alkali. After adding 0.06 mol of phosphoric acid (H3PO4), aqueous ammonia was added to adjust pH to 9.0, followed by stirring at ...
Industrial waste is immobilized in an apatite ceramic matrix by (a) preparing a homogeneous powder mixture of calcium phosphates selected from Ca(H2PO4)2, Ca(H2PO4)2.H2O, CaHPO4, CaHPO4.2H2O, alpha - or beta -Ca3(PO4)2 in amorphous or apatite form and Ca4(PO4)2O, optionally ...
