The phrase "assay equivalent" is correct and usable in written English.
It can be used in contexts related to scientific or analytical comparisons, particularly in fields like chemistry or pharmacology.
Example: "The assay equivalent of the new drug was determined to be significantly higher than that of the existing treatment."
Alternatives: "analytical equivalent" or "test equivalent".
In a dose response assay, equivalent amounts of rAAV/cFIX serotypes were tested in vitro and in vivo.
For the hemizygous experiments and the competition assay, equivalent quantities of mock-transfected cells seeded in 24-well plates were used to subtract the background fluorescence.
c Armored RNA West Nile virus (HNY1999) standard (Ambion, Austin, TX) was diluted 1 10, boiled, reverse transcribed, and then diluted to result in amounts per PCR assay equivalent to the indicated dilution of the stock (5 μL).
After the whole cell protein extracts were quantified using the BCA (bicinchoninic acid) protein assay, equivalent amounts of cell lysates were resolved by 10% SDS/PAGE and were transferred onto polyvinylidene fluoride membranes.
In suspension assays copper (II) sulphate tested at the level found in the WT extract (0.56 μM added to assay, equivalent to level of 0.14 mg L-1 found in WT) was found to have the same effect as a buffer control on the viability of S. aureus NCTC 06571.
In the SH2-PLA assay using 0.5 μg of lysate per assay (equivalent to ~3,000 cells), we also observed a modest but significant signal (lower Ct value) in the same sample confirming the presence of tyrosine phosphorylated EGFR (lower panel), even though its level of phosphorylation was significantly lower than that of A431 cell samples (upper right panel).
Absorbance was read on a UV-160 spectrophotometer (Shimadzu, Kyoto, Japan) and results are expressed as catechin (acid-vanillin assay) and perlargonidin (PC assay) equivalents.
For western blotting assays, equivalent numbers of cells were harvested and lysed as described previously (Wu et al, 2005).
The results showed that, at the maximum molar concentrations used in the cytotoxic assays (equivalent to 100 μg/mL), the peptides did not exert any hemolytic effect (Supplementary Figure 4).
For the DiSC-assay, it has also been demonstrated that it runs more reliable than colony-forming assays that measure clonogenic growth and that results obtained by DiSC-assay are equivalent to both, the colony-forming assay and the colorimetric MTT-assay [ 32, 36].
It has higher sensitivity than the cytotoxicity assay and equivalent specificity.
