Among these methods, the methods of freeze-thaw cycling with NH4OH and TX100 with 1.5M KCl showed the best effect on the removal of cellular components from the complexes, while the other five methods could only partially remove cellular components. The ECM scaffolds prepared by these two ...

An electrode for electrolysis of solutions of electrolytes comprising a support of passivated film forming metal or alloy thereof, having a composite coating consisting essentially of oxides of metals selected from the group consisting of iridium, ruthen
The bath was rinsed with a solution of the following composition: NaCl 96 mM, KCl 2 mM, CaCl2 1.8 mM, MgCl2 1 mM, HEPES 5 mM (titrated with NaOH to pH 7.4). These experiments were carried out at room temperature. The following were employed for data acquisition and analysis: Geneclamp...
Cold incubation buffer (composition: 1.2 mM MgCl2, 22 mM HEPES, 11 mM glucose, 3 mM KCl, 136 mM choline chloride, pH adjusted to 7.3 with TRIS base) was added slowly to the suspension for a total volume of 30-40 mL. This mixture was centrifuged at 7,000 rpm (5,856 g) for 5 ...

Using these conditions, three fractions of HL-A antigenic activity, as determined by specific inhibition of cytotoxicity, were obtained; (1) a fraction extractable by 3M KCl; (2) a fraction not extractable by 3M KCl but extractable by isotonic saline; and (3) residual activity not extractable...
Then, electrodeposition at a constant potential (-0.20V vs. Ag|AgCl|KCl (3M)) in 0.5M H2SO4 solution containing 5.0mM H2PtCl6 was performed for dispersion of Pt nano/microparticles for fabrication of the Pt/P2MA-SDS composite. The as-formed Pt/P2MA-SDS/MGCE was characterized by scanning...
