The phrase "assay water" is correct and usable in written English.
It is typically used in scientific or technical contexts, particularly in chemistry or environmental science, to refer to water that is used for testing or analysis purposes.
Example: "The laboratory requires a sample of assay water to conduct the necessary tests for contamination levels."
Alternatives: "testing water" or "analytical water".
Most of the IA tests are designed to be sensitive enough to assay water samples directly without concentration or clean-up steps.
In this assay, water drop did not collapse and remained in the form of a bead, however, the positive control (SDS) and the BS solution collapsed (Additional file 1: Figure S1).
Prior to the PER-GRS assay, water was offered again in order to avoid confounding thirst effects.
The MTS assay (water soluble tetrazolium salts) reflects cell proliferation and the metabolic activity of the mitogen-stimulated lymphocytes.
After 4 h in the rapid leaf dehydration assay, water loss from the leaf was low and at a stable rate.
The ferric complex reducing abilities of different fractions were similar to the results obtained for the radical scavenging assay; water fraction exhibited very strong ferric ion reducing activity, and the five fractions in descending order of strength of ferric ion reducing activity were water fraction > ethanol extract > butanol > chloroform > hexane fraction.
In this study, biochar samples treated with and without ozone were analyzed by means of pH and CEC assays, water field capacity measurement, elemental analysis, methylene blue adsorption, and Raman spectroscopy.
Ward [3] assayed water soluble chemoattraction in radial gradients of attractant.
For drought stress assays, water was withheld from banana seedlings grown in soil and samples were collected when the soil moisture content reached different stress degrees as outlined by Hsiao (1973).
For quantitative PCR, 40 ng total RNA wasreverse transcribed to cDNA and added to 10 μL of TaqMan® Universal PCR Master Mix, No AmpErase® UNG (2x), 1 μL of the specified TaqMan® Gene Expression Assay, and water to a final reaction volume of 20 μL.
A fast and convenient protocol was established, which takes no more than two days to start from the set-up of reaction to the final assay of water channel activity.
