Sentence examples for microarray probe level from inspiring English sources

Hence differences among the observed microarray probe level distributions are attributed to experimental effects and the normalization is designed to equal all these distributions.

Two existing normalization methods, QPN and qspline [22], [79], minimize between-chip variation by nonlinear transformations that map all microarray probe level distributions onto the average distribution of the constituting data set.

The microarray probe-level intensity was read from cel files directly.

GC Robust Multi-array Average (GCRMA) background adjustment, quantile normalization and median-polish summarization on Affymetrix HGU133 plus 2.0 microarray probe-level data were performed using R 2.7.1 and Bioconductor 2.2.

After the microarray probe set level data was regressed to the gene level and all three sources were merged, 60 950 pair-wise GIs based on 19 evidence types were obtained (see Supplementary Table S1).

For microarray data, probe level quantile normalisation (Bolstad et al, 2003) and RMA (robust multi-array analysis) (Irizarry et al, 2003) were performed using the affy package of the Bioconductor project (http://www.bioconductor.org).

We compared fold changes of the average of values for the qRT-PCR on the candidate exons with microarray probe set inclusion levels (see examples in Figure 6, compare blue lines with red bar graphs, respectively).

We have also analysed the microarray data at the probe level, again yielding similar results.

Gene expression data will be analysed using our previously published probabilistic method for analysis of microarray data that improves probe level sensitivity [ 24- 26].

Twenty-three genes, which were differentially expressed between adjacent normal and tumor samples, were further selected for Q-RT-PCR analysis and were examined by microarray analysis with several probe level quantile normalization methods using either DDX5 or GAPDH as internal controls.

Moreover, the nuID makes the external reporting of microarray results feasible at the probe level.
