However, the absolute values differ between the different assay systems used in the different studies.
Differences in the different assay results between the groups were analysed with the Mann-Whitney U test (P(U)).
This difference may be explained by different assay protocols and use of different secondary antibodies.
This discrepancy could be due to the use of a different assay, associated to a regional difference in estrogen catabolism.
We note this difference in affinity values (presumably resulting from the very different assay formats) in the discussion.
In addition to compositional differences, the HHL APEX array and the Affymetrix resequencing arrays employ different assay methodologies.
Furthermore, differences in ovulatory progesterone concentrations between studies may partly result from different assay systems.
The ROC for different assay approaches and time between blood draws calculated from 100,000 simulated titre responses.
Since B49Mod1 inhibits adhesion-independent cell growth, we used a different assay to evaluate the effect of B49Mod1 in long term cell growth.
In this report, different assay designs were used to illustrate how design may adversely affect specificity.
Here, we describe different assay conditions that eliminate these problems (BHIA, β-hematin inhibitory activity).
