On London's streets, Pryce was documenting the very trend -- from the East End to the sophisticated Savile Row, hipsters to high-profile people, young lads to middle-aged and elderly men, beards have not only become a symbol of masculinity, but also a representation of individual expression and elegance.
We chose organs and glands to obtain as wide a representation of gene expression in the mouse as possible.
This may result in decreased fidelity in the ratio of cDNA to genomic DNA as a representation of gene expression level.
In essence, the above procedure generates a representation of differential expression that is amenable to probabilistic modeling with topic models, and for topic model-based information retrieval tools.
A scaling factor can be applied to lift at this stage, and then the log2 of each normalized read count was calculated as a representation of the expression level.
It is also used as a representation of mathematical expressions in other formats, such as SBML and CellML, two of the model representation languages supported by SED-ML.
In this way, transcriptional responses and changes in protein states can be studied for patterns of causation that suggest much more specific mechanistic hypotheses than are apparent in a static representation of expression data such as a heatmap.
The expression correlation data were then analyzed with Cytoscape Lopess et al, 2010) to draw a visual representation of expression relationships among genes.
Conventional annotation methods measuring the over-representation of functional categories, such as the performed KEGG-pathway mapping may lack an adequate representation of expression data in the functional specific cellular context.
The ΔCp value approaches a log2-fold representation of expression levels.
cDNA normalization is an efficient way of limiting over-representation of genes with high expression rates, and ensuring a representation of genes with low expression rates.
