The SEM analysis was performed on preformed biofilm treated with effective concentration of biosurfactant as determined in the microplate assay.
The effect is further limited by using the minimal effective concentration of the crosslinker, as determined by preliminary titration experiments.
From the data in Figure 1, the lowest effective concentration of each SKI was determined (inhibition < 50%) and double or triple combinations of each SKI were compared with each inhibitor alone.
The resulting "excluded volume effect" stipulates that the effective concentration of a test solute is determined by the number of molecules of that solute per unit of available volume, rather than the total volume.
Toxicant solubility is a physiochemical determinant of tissue distribution and, consequently, determines the effective concentration of the electrophile at the target.
No attempt was made to determine the effective concentration of dissolved oxygen in the liquid medium.
To determine the effective concentration of caffeine and zeocin, we tested the survival of S. quadricauda cells in the presence of different concentrations and combinations of zeocin and caffeine.
Upon drug treatment, the cell viability assay was employed to determine the effective concentration of AST.
Then, we investigated the effects of B-ext, L-ext, and NAC, a positive control antioxidant, at various concentrations, and we determined the effective concentration of each agent.
The antibody titer from the rabbit blood was measured and effective concentration of the antibody for immunohistochemistry was determined empirically.
We therefore determined the median effective concentration of sufentanil required to provide excellent analgesic effects in these patients after sevoflurane anesthesia.
