The phrase "also at a concentration" is correct and usable in written English.
It can be used when discussing the presence of a substance or element at a specific concentration level in a scientific or technical context.
Example: "The solution contains sodium chloride, also at a concentration of 0.9%."
Alternatives: "additionally at a concentration" or "likewise at a concentration".
The Fe3O4 NPs are added dropwise (also at a concentration of 7 mg/mL), and the infiltration process is accomplished by diffusion of the nanoparticles through the side porous wall of the SiNT.
Both genistein at a concentration of 100 and 300 μ M and tryphostin A23, also at a concentration greater than 100 μ M, completely attenuated the PIF-induced increase in proteasome activity.
The proliferation rate of the cells was strongly stimulated by the addition of exogenous GHRH, not only at the concentration of 0.1 μ M but also at a concentration of 1 μ M. The silenced cancer cell lines, lacking intrinsic GHRH, were still able to respond to exogenous GHRH, confirming the absence of possible toxic effects related to the transfections.
This observation is found consistent with increase in EVA-g-MA concentration at a fixed MA level and also at a fixed concentration of dispersed phase with different level of MA in binary and ternary compositions.
For CXCL8, this was also observed at a concentration of 0.1 EU/ml.
Phenanthrene, one of the aromatic hydrocarbons, was also examined at a concentration of 0.1 wt% and even at this level was found to have a strong signal-to-noise ratio.
Furthermore, PFNA was also detected at a concentration of 31 ± 4 μg/kg (GD 18).
With mAb 654-D, an IC50 was also achieved at a concentration of <0.3 µg/ml (Table 1).
In addition, a slight increase in Met-83 oxidation was also observed at a concentration of 0.7% TBHP, albeit to a different extend when compared with the experiments applying H2O2 as oxidizing reagent (Table 1).
IFNQ was also used at a concentration of 1 mM.
Hfq alone was also run at a concentration of 173 μM.
