In the midgut, an apico-basal gradient of expression was observed with highest levels towards the basal regions of the midgut cells (Fig. 9A,B; For quantification methods and results see Fig. 9I K and Materials and Methods).
Second, the technique itself could be expanded to take into account data parameters and quantification; the formulæ described in Section 'Sample properties' gave a foretaste of such quantification and initial results indicate that quantification is a fertile ground for parallelism.
PCR enrichment performed prior to RT-PCR increased the accuracy of quantification and produced results similar to those detected with SYBR-Green.
For relative quantification and microarray results validation, we selected primer sets and probes, matching sequences present in the IMAGE human cDNA clones of the nylon microarrays with those displayed on the web portal of Applied Biosystems.
Titre of Barley yellow dwarf virus (BYDV) was determined in oats using relative quantification with different reference genes and absolute quantification, and the results were compared.
The technology-dependent modules for microarray data (Refiner Array), mass spectrometry (Refiner MS, used in the present study) and genomic profiling (Refiner Genome) allow highly-sophisticated data processing, quantification, visualization, and result exporting in any generally-used formats.
The comparative threshold method for relative quantification was used, and results are expressed as relative gene expression for each target gene.
Data analyses were performed using Q-gene qRT-PCR analysis software (Gene Quantification (http://www.gene-quantification.info/) [44] and results were expressed as Mean Normalized Expression (MNE) relative to the reference gene.
Given the diversity of quantitative scenarios this review illustrates the scenario design and its quantification, and evaluates the results of land use/cover changes on a European level.
(C ) Quantification and statistical IEI results are shown for data in (B ).
Gene quantification and differential analysis results are dependent upon the initial choice of gene annotation [ 19– 219.
