Sentence examples for technical variances from inspiring English sources
Here we introduce a method that exploits a small pilot study to estimate the biological and technical variances in order to improve the design of a subsequent large experiment.
In addition to these technical variances, the limited sample size and the heterogeneity existing among the cancer subgroups are noted as other major factors affecting the selected markers.
For these genes, both technical variances and within-group variances are small, compared to the between-group variances.
In addition, the large number of differentially expressed genes we observed may reflect the high sensitivity and repeatability of the microarray methodology employed, where small technical variances generated high power for the detection of differential expression.
To account for biological and technical variances inherent in this meta-analysis, only genes reported in more than one publication as differentially regulated were kept in our core dataset.
Technical variance is dependent on the protocol employed within a quantitative proteomics experiment and accumulated with every additional step.
Our results indicate that the technical variance dominantly contributes to the total variance in mouse brain and the genetic background has a negligible effect on the total variation.
It has been widely assumed, although not yet empirically verified, that early combination of samples minimises technical variance in relative quantification.
Different allocations of biological and technical replicates were evaluated by minimizing the variance of the ratio of technical variance (measurement error) to the total variance (sum of sampling error and measurement error).
The biological variance in protein expression of interest to biologists can only be accessed if the technical variance of the protein quantification method is low compared with the biological variance.
According to these guidelines, ΔCT values ≤ +/−0.5 are considered fluctuation in gene expression that is largely due to technical variance (e.g., unequal loading, PCR efficiency, etc).
