The phrase "average optical density" is correct and usable in written English.
It can be used in contexts related to photography, imaging, or scientific measurements where optical density is being quantified.
Example: "The average optical density of the film was measured to determine its exposure level."
Alternatives: "mean optical density" or "typical optical density".
(b) Average optical density at 430 nm upon WST-1 reduction by CS exposure.
AWCD590nm was used as an indicator of general microbial activity and was assessed as the average optical density of all wells per plate (Zhang et al. 2014).
By comparing the average optical density of the growth in control wells with that in the sample wells, the following formula was used to calculate the percentages of inhibition for each concentration of the sample: Inhibition % = O D 570 growth control – O D 570 sample O D 570 growth control × 100 (2).
By comparing the average optical density (O.D). of the growth control wells with the sample wells, the following formula was used to calculate the percentages of inhibition for each concentration of the sample: inhibition % = OD growth control - OD sample OD growth control × 100 (100
The average optical density (OD) of these areas was automatically calculated (0 255: 0 = dense amount and 255 = none).
Quantitative analysis of human azoospermia samples was performed by Metamorph software, with average optical density of ten random fields were compared for each sample.
All experiments were performed in a blinded manner and in duplicates, and the HER2 concentration was calculated using their average optical densities based on standard curves.
Average optical densities were evaluated only in patients showing positive immunoreactions.
Quantitative analysis indicated that the average mean optical density (MOD) of TBLR1 staining in clinical stage I to IV primary tumors were statistically significantly higher than the value in normal breast tissues (P <0.001; Figure 2B).
The averaged optical density reading was then compared to a known standard of monophosphate to calculate the concentration of phosphate released.
The mean optical density (OD), as a quantitative measure of stain intensity, was analyzed to determine average protein expression.
