The phrase "assay solution" is correct and usable in written English.
It can be used in scientific or laboratory contexts, particularly when referring to a liquid mixture used for testing or analysis.
Example: "The chemist prepared an assay solution to determine the concentration of the substance in the sample."
Alternatives: "testing solution" or "analysis solution".
Then, 100 mg of 5-sulfosalicylic were added to the CAS assay solution and stored in the dark.
After drying, samples were redissolved with 5 ml distilled water as assay solution and used for assays of trehalose.
The increase in fluorescence intensity is directly proportional to the amount of Cu2+ added to the assay solution.
In order to quantify the siderophores, 0.5 ml of the culture supernatant was mixed with 0.5 ml from the prepared CAS assay solution.
Coating antigen: SSd BSA; blocked with 1% BSA; assay solution of 0.05 M carbonate buffer solution (pH 9.6); Color reagent: TMB.
It showed the theoretical lowest limit of detection enabled by the affinity of the anti-OTA antibody (IC80 = 12 ng L−1 in the assay solution).
With the GPPD labeling method, dependence of the electrochemical signals on the incubation time and pH of the assay solution were also studied.
The percentage of siderophore units was estimated as the proportion of CAS color shift using the formula [(Ar − As)/(Ar)] × 100, where Ar is the A630 nm of the reference sample (TSB + CAS assay solution + shuttle solution) and As is the A630 nm of the sample (supernatant + CAS assay solution + shuttle solution).
Therefore, with the binding of the same amount of antibody to the protein complex-GNP conjugates, the particle size should be just slightly smaller in the case of anti-Src assay solution than anti-Stat3 assay solution.
The addition of a polyclonal antibody itself to the assay solution did not cause significant nanoparticle size change.
To investigate the influence of pH, an assay solution pH range between 4 and 9 was used.
