The phrase "activities to correct" is correct and usable in written English.
It can be used when referring to tasks or actions aimed at rectifying a problem or improving a situation.
Example: "The report outlines several activities to correct the issues identified during the audit."
Alternatives: "actions to rectify" or "measures to address".
Luciferase activity was normalized to β-gal activity to correct for transfection efficiency.
Luciferase activity measurements were normalized for β-galactosidase activity to correct for differences in transfection efficiency.
Firefly luciferase activity was normalized to renilla luciferase activity to correct for transfection efficiency and the reporter gene expression presented as relative luciferase units (RLU).
The ratio was normalized for the Renilla luciferase activity to correct for variations in transfection efficiency.
In fact, respiratory chain enzymes activities were expressed relative to citrate synthase activity, to correct for any difference in mitochondrial density (possibly due to edema, for instance).
Luciferase activity was measured 48 h later using the Luciferase Assay System (Promega), and normalized to β-galactosidase activity to correct for small changes in transfection efficiency.
From there, the luciferase activity of each sample was normalized to the LacZ activity (luciferase activity/LacZ activity) to correct for transfection efficiency variability, and the ratio luciferase with Gcm/luciferase without Gcm was calculated.
The firefly luciferase activity from the indicator cells was normalized against the Rellina luciferase activity to correct for transfection efficiency of Ptch1 constructs in the testing Ptch −/− MEFs as the measurement of non-cell autonomous inhibition by Ptch1.
This provides a plausible explanation for the relation between increased rACC activity to correct trials and repetitive behaviour.
