The phrase "a valuable sample" is correct and usable in written English.
It can be used when referring to a sample that holds significant worth or importance, often in research or analysis contexts.
Example: "The researchers collected a valuable sample of soil from the ancient site to study its composition and history."
Alternatives: "an important specimen" or "a significant sample".
Pleural effusion is a valuable sample source for observation of changes in VOMs for differentiation between lung cancer patients and inflammatory individuals.
The wealth of texts found there, recording troop movements, provisions and other daily activities, were created within a short time, making them a valuable sample for looking at how many different hands wrote them.
In arid regions, pedogenic carbonate (calcrete, caliche) may be a valuable sample medium for Au exploration, principally in erosional regimes, and in depositional areas where the overburden is shallow.
Nevertheless, the selected set of 254 full-length REs constitutes a valuable sample of these sequences, allowing an analysis of RE dynamics in this species.
We modified this method assessing its performance with a clinically relevant body fluid, quantitatively analyzed experimental repeatability including well-to-well and plate-to-plate variability, addressed questions of centrifugal speed and protein load capacity (loading range of 10 70 μg total protein) and applied the method to urinary pellets, a valuable sample source for UTI diagnostics.
These sequences also represent a valuable sample of intraspecific diversity and might furthermore present clues on where to look for previously undescribed species, but in the end it is the standard and level of detail of the metadata for each sequence that will determine the ease and extent to which this information can be utilized.
No obvious differences in protein recovery could be observed whether sampled wound fluid was directly frozen on the soaked swab (protocol 1) or recovered by centrifugation prior to freezing (protocol 2) (Fig. 3 A ). Rapid swab freezing after sample collection therefore represents a valuable sample-processing protocol for daily clinical routines in particular with respect to saving handling time.
Within the same period, the magnitude of the stimulatory effect of activin A is greater [ 24], further indicating that a valuable sampling for related biomarker measurement would be within this interval.
The FinESSI study represents a population-based birth cohort study of SSRI use and infant/childhood outcomes until age 14, capitalizing on a unique and highly valuable sample consisting of all singleton offspring of women in Finland who received SSRI's during pregnancy from 1996 2010.
When considering the findings from this valuable sample the logistic regression revealed a significant occurrence of hypoplasia and post-eruptive breakdown occlusally.
In the era of functional genomics, the valuable sample of twins is helping to bridge the gap between gene activity and the environments through epigenetic mechanisms unlimited by DNA sequence variations.
