Endothelium-dependent relaxation was measured by testing the concentration-response relationship upon the cumulative addition of acetylcholine (Ach, 1 nmol/L to 10 μmol/L) to phenylephrine (Phe, 1 nmol/L to 10 μmol/L -precontracted rings.
No effects were found by testing the higher concentration of 200 mg/l.
The variations in the interassay were assessed by testing the triplicate of each concentration in a single round of real-time PCR and the variations in the intra-assay were assessed by repeating three rounds of MB rRT-PCR.
By testing the inhibitors at different concentrations, we were able to first define a starting point for the experiments, which consisted in a concentration that inhibited the majority of cells (> 95% of cells showing a dominant mislocalization).
The reproducibility of the GNP-SiNR-based LFSB was studied by testing the sample solutions at different concentration levels (0, 0.5, 5, and 50 ng mL 1 rabbit IgG).
We previously optimized PCR conditions for each amplification by testing the following conditions: annealing temperature, magnesium concentration and cycle number.
This can be done by spiking various concentrations or by testing the response factors of the spiked compounds.
A second experiment was conducted with Indian soil and Bambusa, designed to test the concentrations achieved by pulsing deliveries and adding larger total quantities of -catechin into the soil over time.
The optimal concentration of TNF-α was established by testing a concentration range of 0.1, 0.5, 1.0 and 10 ng/mL.
Any effect of inulin or trehalose on the hemagglutination and hemolysis assay was excluded, by testing a similar concentration of the freeze-dried sugar without viral particles.
