In contrast, the strong inhibitor oleic acid did not cause significant spectral changes. NOR which had been reduced by L-ascorbate/phenazine methosulfate prior to incubation with its susbtrate NO gave the characteristic Fe(II) nitrosyl triplet centered at g&asymph;2.01, with a hyperfine splitting ...
The pelleted cells were washed and homogenised with 1 mL of 10 mM TRIS-HCl (pH 8; tris (hydroxymethyl) aminomethane), 1 mM EDTA (ethylenediaminetetraacetic acid), 0.5 mM EGTA (ethylene glycol- bis (2-aminoethylether)-N,N,N′,N′-tetraacetic acid), 140 mM NaCl (sodium chloride), 1 ...
An EGFP-positive transformant was selected on hygromycin and grown in Middlebrook 7H9 medium (Difco) supplemented with 10% oleic acid-albumin-dextrose-catalase (OADC, Difco), 0.2% glycerol, 0.05% Tween 80, and 50 μg/ml hygromycin (all from Sigma-Aldrich, St. Louis, MO, USA) ...
CS was evaluated at 420 nm in 75 mM Tris-HCl (pH 8), 100 μM 5,5'-dithio- bis-(2-nitrobenzoic) acid (Sigma), 350 μg/ml acetyl- coenzyme A (Sigma), 0.5 mM oxaloacetate (Roche Diagnostics) and 0.1% Triton X-100 (Sigma). Measurement of MRC complex activities...
Metal dependence of gelatinolytic activities was confirmed by incubation of duplicate gels in the presence of 0.01 mol/L ethylenediaminetetraacetic acid (EDTA) in the developing buffer, which resulted in the disappearance of lytic bands. Cell-free incubation experiments In these experiments, the ...
the gels were incubated in 50 mM Tris buffer pH 7.4, containing 0.15 mM NaCl and 30 mM CaCl2, for 18 h at 37 ° C. Gels were stained with Coomassie blue and then destained with 10% acetic acid and 30% methanol in water. The areas of proteolytic activity appeared as negative-stained...
This is especially interesting, because it sheds new light on amino acid distribution in cells as well as on the arginine paradox. The arginine paradox predicts that extracellular L-Arg can increase NO production, despite the fact that intracellular levels of this amino acid are much higher than...
Oligogalacturonic-acid-sized25 fragments would be ahead of the RuR-stained materials on the basis of comparison with a previous publication47. Active species for ovular NO induction remains to be determined. c, Representative quantification of PGA-induced NO response based on filiform apparatus:...
Esculetin protects against cytotoxicity induced by linoleic acid hydroperoxide in HUVEC cells, and the radical scavenging ability of escule- tin was confirmed by electron paramagnetic resonance spectroscopy21. However, as coumarins may have reduced bioavailability in vivo and do not significantly ...
