The phrase "at selected time points" is correct and usable in written English.
It can be used in contexts where specific moments in time are being referenced, often in scientific or research settings.
Example: "The data was collected at selected time points to analyze the effects of the treatment over time."
Alternatives: "at specific intervals" or "at designated time intervals".
Milk samples were collected and analyzed at selected time points after treatment.
Brachiocephalic arterial and sagittal venous blood were sampled at selected time points for blood gas and pH, oxygen content, and glucose and lactate levels.
This implies that the gas volume through the meter is measured by sampling the flow rate at selected time points and integrating the flow rate in time.
(A) Representative histograms of GFP fluorescence in wild-type (blue) and ∆yeaG mutant strain (red) populations at selected time points following induction of GFP expression during 'recovery' growth (after 24 h N starvation).
This paper introduces and demonstrates design-based Generalized Least Squares (GLS) estimation of spatial means at selected time points from data collected in repeated soil surveys with partial overlap, such as a rotating and a supplemented panel.
At selected time points, the supernatant was removed, and cells were washed with 0.1 M glycine HCl pH 2.5 to remove cell-surface bound F3.
Blood samples were collected at selected time-points up to 48 h after dose.
In fact, this approach, based on a spatio-temporal imaging analysis of the metastatic process, does not require the sacrifice of mice at selected time-points to evaluate tumor and metastasis growth.
At selected time-points (30 minutes to 6 hours), mice were sacrificed by pentobarbital overdose, and the lung, liver, small intestine and kidney were removed for subsequent analyses.
In summary, in this study we explored the changes in gene expression that occur in the lung at selected time-points following E. coli infusion in baboons.
Graphs show the average fluorescence intensity profile of ≥10 centrosomes ('Materials and methods') at selected time-points after photobleaching (t = 0).
