The phrase "ascertain the activation of" is correct and usable in written English.
It can be used in contexts where you need to determine or verify whether something has been activated or is functioning.
Example: "The technician was called in to ascertain the activation of the new security system."
Alternatives: "verify the activation of" or "confirm the activation of".
To ascertain the activation status of IRE1 after ER stress, we examined XBP-1 mRNA splicing in parental ESCs-FLAG and ESCs-FLAG-AR.
This study attempts to ascertain whether the activation of semantic memory during REM-sleep, as measured using a technique of semantic priming (namely, the facilitation of the activation of strongly-related rather than weakly-related and, overall, unrelated pairs of prime-target words) is different in NC patients compared to normal subjects.
To ascertain whether the activation of Akt and ERK 1/2 can be due, at least in part through Ras activation, we performed Ras assay with different construct of Ack1: full-length (Ack1), kinase hypoactive (Ack1-KD), and proline rich (Ack1-PR).
We examined the fetal Leydig cells population in E18.5 testis to ascertain the tamoxifen independent activation of the Cre recombinase, and there was no difference between the control and mutant mice.
To further ascertain the effect of DOR activation on the antioxidant mechanism, we examined the changes in NO, another critical free radical that causes brain injury in ischemia/reperfusion [ 24, 25].
To further ascertain the role of Fyn in the activation of GHS-R1a by ghrelin, we found that ghrelin induced a stronger recruitment of activated Fyn kinase to the GHS-R1a in a time- and dose-dependent manner in THP-1 cells, reaching a 5-fold increase within 30 min of treatment (Fig. 4C).
To ascertain what may be causing the activation of TGF-beta within the H69 treated cells, staining for beta6 containing integrins was performed.
ARVMs were treated with vehicle or PMA (to activate PKD) to ascertain the potential impact of PKD activation status on any interaction with FHL1 or FHL2.
Further study is necessary to ascertain the significance of vasopressin P2R activation in the human heart, but the discovery that vasopressin acts on P2Rs is intriguing.
A third group of COUP-TFIIflox/flox animals received IP tamoxifen to ascertain the effect of tamoxifen independent of the activation of the Cre recombinase (Fig. 1A).
