As expected, data between RNA-seq and microarrays were less similar than microarray-to-microarray, likely due to their distinct data distribution (Poisson vs. Gaussian).
For each transcript, there is a probe set containing proximately 11 probes (99.58% of 57381 probe sets for rice microarray) on microarray to detect its the expression signal.
A standard normalization procedure was applied to the quantified gene expression values obtained for each printed microarray to facilitate comparisons among individual microarrays (Affymetrix GeneChip Expression Analysis technical Manual, 2004).
Therefore, according to this measure, SEM data was filtered according to tomato microarray – potato microarray probe homology (i.e. E-value or bit-score) to create subsets of SEM.
To investigate whether MAMA can predict cis-elements in other microarray data, we applied it to microarray data from rice root subjected to zinc (Zn) deficiency (Suzuki et al. 2012).
Prior to microarray hybridization, each microarray was allowed to equilibrate at 4C for at least 15 min and then pre-blocked in 25 30 mL Blocking Buffer (1X PBS; 1% BSA w/v; 1 mM DTT; 50 µg/mL E.coli tRNA; 20 µg/mL heparin) at 4°C for 2 hours with gentle shaking.
RNA derived from EWS-FLI-1, EWS-ERG, FUS-ERG (AML), FUS-ERG (ESFT), ERG-1 and FLI-1 expressing MPC populations were all subjected to microarray analysis; five m17k microarrays (among which 2 were dye swaps) were performed for each population, comparing cells expressing the protein of interest with the corresponding empty vector control cells.
Microarray data were deposited (according to Microarray Gene Expression Data Society Standards) in the NCBI Gene Expression Omnibus with the series accession number: GSE6944 [ 55].
Although detection of serum autoantibodies are shifting from ELISA platforms to microarray slide formats, microarray technology requires sophisticated fluorescence detection scanners they are not currently accessible in most parts of the world.
The poorer performance of CD4+ T cell (CD4) samples normalized to PIAS1 suggests that this gene was not as invariant as indicated by its microarray expression values, perhaps due to microarray saturation.
The expression pattern of a number of genes likely to be related to fruit quality was validated by quantitative real-time PCR, and the data from papaya cross-species microarray was compared to microarray data from tomato (a climacteric fruit) and grape (a non-climacteric fruit).
