The phrase "assay log" is correct and usable in written English.
It can be used in contexts related to scientific or laboratory work, particularly when referring to a record of assay results or experiments.
Example: "The researcher meticulously documented each result in the assay log to ensure accurate data analysis."
Alternatives: "test record" or "analysis log".
For tumour cell motility assays, log phase MDA-MB-231 cells (5 × 104 cells) were suspended in 10 μg/mL control or tamoxifen mammary gland ECM, and overlaid onto transwell 8 μm pore filters as described above.
For spotting assays, log phase cells grown in liquid YPAD were diluted to 1.0 × 106 cells/ml (~0.1 OD units) and 5-fold serial dilutions spotted (5 μl/spot) to YPAD or YPAG plates and incubated for 2 3 days at 18°C, 25°C, 30°C and 37°C.
The values of optical density (for SRB), colony count (clonogenic assay), or luciferase unit (luciferase assay) were log transformed to stabilize the variance of the residuals.
For survival curves obtained in starvation and desiccation assays, log-rank (Mantel-Cox) test was performed to analyze the trends in lifespan.
For spotting assays, log-phase cultures were adjusted to an OD600 of 0.1 or 1 for type I survivors, and serial five-fold dilutions were plated on YPD followed by exposure to different temperatures, ionizing radiation (IR), UV light, or YPD containing various concentrations of glucose, bleomycin (BLM), methyl methanesulfonate (MMS), H2O2, or hydroxyurea (HU).
This semi-quantitative assay is based on linear signal amplification with an analytical limit-of-detection of approximately 2500 virus copies per assay and 3 4 log dynamic range.
For each assay, the log of the fraction growth inhibition was plotted against the log of drug concentration, and the linear regression curve fit correlation coefficient (r value) was calculated.
For each assay, the log of the fractional growth inhibition was plotted against the log of the drug concentration and the linear regression curve fit correlation coefficient (r-value) was calculated.
Using the results of a calibration study in 295 subjects whose samples were assayed using both methods, the results of the earlier CRP assays were adjusted to the Glasgow assay, for which the current CRP international standard was used by subtracting −0.128 from the earlier log CRP assay (87.9% of the original value).
Similar results were obtained with the plaque assay (1.3 log inhibition versus untreated cells, P < 0.01; Fig. 5D).
