Example: "The report highlighted an activity which was not included in the original plan."
Alternatives: "action that did not" or "event that was not".
Using a NANOG-driven GFP reporter, we found a large fraction of N-RAS61K-AR cells with activated Nanog promoter activity, which was not observed in N-RAS61K cells.
HIV and FV proviruses containing an internal MLV long‐terminal repeat (LTR) promoter also had significant enhancer activity, which was not observed with an internal promoter from the murine phosphoglycerate kinase‐1 gene, PGK.
Although SDS-PAGE analysis of eluate 2 showed a very slight band for the hydantoinase compared to the corresponding band in eluate 1 (see Fig. 7a), this fraction revealed a much higher specific activity which was not caused by the lower protein concentration, since the volumetric activity of eluate 2 is higher, too.
Dairy intake may be a marker for other dietary behaviors or related to physical activity, which was not evaluated here.
Co-transfection of this construct together with an expression vector for MYCN in SH-EP cells led to a sharp transactivation of the luciferase activity, which was not detected in the control empty vector group (Figure 1E).
The level of active MMP-2 in the conditioned media from the SPARC−/− cells was reduced in comparison to that from the WT cells, in stark contrast to the level of MMP-9 activity, which was not obviously different between the two cell types (Figure 2B, left panel).
It's now also possible to comment on a user's activity, which wasn't possible before.
This unexpected result was found to be due to a requirement for AhR activation and CYP1A1 expression and activity, which is not uniformly induced by the various individual congeners.
One of the main hubs of activity, which is not to use that in any extreme sense, is around the jetty.
The government is deprived of substantial tax income by informal-sector economic activity, which is not taxed; in addition, tax collection itself is not considered adequately efficient.
