The phrase "activity even at the" is not complete and lacks context, making it difficult to determine its correctness in written English.
It could be used in contexts discussing ongoing actions or behaviors that persist under certain conditions, but it needs additional information to be fully clear.
Example: "The research showed that there was activity even at the lowest levels of engagement."
Alternatives: "activity even during" or "activity even in".
It is dose-dependent and ATP, for example, showed a strong inhibitory activity even at the lowest concentration tested (10 μM).
Additionally, the strong induction of GST activity, even at the lowest H2AsO4− doses studied, can be exploited as suitable biomarker of As toxicity in peanut plants, which may help to detect risks of As accumulation and select tolerant cultivars.
Exposing subtilisin at 90 °C for 5 h led to 18-fold improvement in its transesterification activity even at the normal assay temperature (37 °C) when compared with the untreated enzyme.
"But we have found lots of activity even at the very deepest sites".
Nevertheless, slow manganese dissociation from Mn II OBTMPyP4+ enabled the complex to persist and exhibit catalytic activity even at the nanomolar concentration level and at biological pH.
Metabolite 7 showed a moderate inhibitory activity (IC50 = 25.6 μg/mL), while other compounds did not show any activity even at the highest concentration (100 μg/mL).
Along the entire stimulus sequence small bumps in the dye signal level coincided precisely with the generation of spiking activity, even at low levels during the early phase of the imaged response.
Reassuringly, there was no evidence of an increase in risk at higher levels of physical activity, even at seven times the World Health Organisation minimum physical activity recommendation.
And a mouse study produced evidence that uranium in drinking water caused estrogenic activity even at levels below the EPA safe drinking water level of 30 µg/L.
For ERβ, bisphenol AF was almost completely inactive, with very little increase in activity even at 10 μM, the highest concentration tested.
Indeed, the new ImmunoRNase retains a residual 30% of the enzymatic activity even at a cRI/IR ratio of about 5, whereas the activity of the monomeric IR is completely inhibited at a cRI/IR ratio of about 1.
