We describe procedures for isolating cells carrying the substitutions and for eliminating the products of secondary off-target events.
Science
Further work will be necessary to determine whether the phenotype we observed results from a secondary off-target effect of the Rapgap1 shRNA.
Science
However, anle138b seems to primarily act by directly targeting formation of pathological tau aggregates rather than by secondary off-target effects, since we found unchanged tau expression, tau ubiquitination and autophagy after administration of anle138b.
Science
Plasminogen activator inhibitor-1 protein levels were also moderately reduced in scrambled control compared with non-transfected cells, which could be attributed to RNAi pathway saturation and/or secondary off-target effects affecting PAI-1 pregulatoryulatory factors, as previously described for other cases (Grimson et al, 2007; Khan et al, 2009).
Science
Treating Dgcr8−/− ESCs with another TGF-beta receptor inhibitor RepSox or another GSK3 inhibitor BIO induced similar phenotypes; therefore, the observed phenotypes were unlikely to be secondary to off-target effects.

Expert writing Tips
Best practice
When using "secondary off", ensure the context clearly indicates what the 'secondary' element refers to. Avoid ambiguity by specifying the system or feature being deactivated.
Common error
Avoid using "secondary off" in general contexts where a more descriptive term like "disabled" or "inactive" would provide clearer communication. Ensure that the 'secondary' aspect is relevant and understood by the audience.

Ludwig's WRAP-UP
In summary, the phrase "secondary off" is a relatively uncommon expression used to indicate that a secondary system or feature is deactivated. As Ludwig AI reports, its grammatical status is acceptable, but its usage is rare and context-dependent, primarily appearing in scientific and news media sources. When using this phrase, ensure clarity by specifying what the 'secondary' element refers to. Alternatives like "auxiliary off" or "secondary disabled" may provide greater clarity in certain contexts.

Uses "backup" for secondary and "deactivated" for off, indicating a system is no longer active.
supporting system offline
Indicates the supporting system is not connected or operational; more descriptive.
secondary system shut down
Emphasizes the action of shutting down a secondary system; more explicit.
secondary power cut
Focuses on power supply, indicates a power cut to a secondary system.
second instance terminated
More technical phrasing for ending a secondary process or instance.

FAQs
What does "secondary off" mean?
The phrase "secondary off" typically indicates that a secondary system, feature, or component is deactivated or turned off. The exact meaning depends heavily on the context in which it's used.
Which is a better alternative to "secondary off": "auxiliary off" or "secondary disabled"?
Both auxiliary off and secondary disabled are suitable alternatives to "secondary off", but secondary disabled may be clearer in some contexts, emphasizing the state of being disabled. The choice depends on the specific nuance you want to convey.
When should I use "secondary off" instead of "backup deactivated"?
Use "secondary off" when referring to a second system or function being turned off. If the system serves as a backup, backup deactivated is more appropriate as it specifies the system's role.
Is "secondary off" formal or informal?
The formality of "secondary off" depends on the context. In technical or operational settings, it's acceptable, but in general writing, more formal terms like secondary disabled or "supporting system offline" may be preferred for clarity and precision.
