Sentence examples for sample a threshold from inspiring English sources

In the majority of cases, it was possible to obtain >30% tumor cells in the DNA sample, a threshold set for dideoxy-sequencing sensitivity/selectivity in tissues [21].

Although revisiting the dispersion or sample preparation protocol for some materials and methods may result in significant enhancement of the quality of the sample, a threshold needs to be set for practical purposes.

For each sample, a threshold cycle (Ct) value was calculated based on the amplification curves by selecting the optimal ΔRn (emission of reporter dye over starting background fluorescence) in the exponential part of the amplification plot.

Since the content of tumor cells varies between patient samples, a threshold for minimum content of tumor cells within a sample is often applied.

The classifiers trained by Messina decide the class of an unknown sample by comparing the expression of a single gene in that sample to a threshold value.

The presence of other species not expected to live in ocean environment was considered as contaminating the sample and a threshold of 2% per species was arbitrarily defined to invalidate the dataset.

Any sample with a threshold cycle (CT) of <35 was considered to be positive for WNV.

The Ct value was defined as the cycle at which a sample crosses a threshold which is significantly above the background fluorescence and within the exponential phase of the amplification.

$$\end{document} Samples with a threshold cycle higher than the chosen cutoff point are classified as negative, whereas samples with threshold cycle lower than the cutoff point are classified as positive [ 30].

Only samples with a threshold lower than 0.05 were used for sequencing library construction (Table S5).

The first of these measures was representativeness — the number of land systems sampled to a threshold level.
