It can be used when discussing the process of evaluating or analyzing differences between two or more items, concepts, or situations.
Example: "In order to improve our product, we need to assay the difference between customer feedback and our current offerings."
Alternatives: "evaluate the difference" or "analyze the difference".
While the distribution derived from the two tests was fairly similar, follow-up GMTs were 59 95%% CI 41-85) by HI compared to 47 95%% CI 32-68) by VM assay, the difference being of borderline significance (p = 0.06 by Wilcoxon signed-rank test on 44 observations).
A significant difference was seen as early as 48 hours with the BrdU assay, whereas with the MTT assay, the difference was seen after 4 days.
In the FIBTEM assay, the difference between median A10 and MCF was 1 mm in the MT group and 2 mm in the non-MT group.
As similar concentration of fibrillar BSA-Zwit and BSA-S200 was used in the cytotoxic assay, the difference in potency is likely due to factor(s) other than concentration of amyloid fibrils.
In the case of the cytotoxicity effect of Maldi 531.2[M + H] + as shown in cell viability tests and annexin V-FITC binding assay, the difference in IC50 values with XTT at 0.02-0.03 uM and the non-significant difference of cytotoxic effect at 0.05 uM with annexin V FITC binding assay for apoptosis, relative to untreated cells, is the time of observation.
The paired-samples t-test was used to assay the differences in the miRNA expression levels between cancer tissues and corresponding adjacent tissues.
Like the lifespan and fecundity assays, the differences among lines in resistance to oxidative stress suggests allelism, as variation in the wild-type background was not greater than variation in the mutant backgrounds (Table 3).
For clonogenic cell survival assays, the differences between groups were analyzed by Student's t-test for each data set points (2, 4, and 6 Gy).
In this context it is important to note that although activation of these four Cup systems results in a similar phenotype in an in vitro biofilm assay, the differences in regulation and organization would suggest that they are not redundant.
Each individual sample was assayed in duplicate and the sample again assayed when the difference between the two results was over 20%.
2) In contrast to the binding assays, the actual differences in relative survival of N. meningitidis in the presence and absence of CFHR3 are rather modest.
