Most delicate of all is sample handling and preparation: RNA quantitation, internal control for cross-library normalization, parallel sampling strategy, appropriate controls, etc. Third, a software package needs to be put together for data normalization across libraries, comparative expression analysis, gene annotations and functional classifications.
Quantitation of control staining with anti-total Akt antibody did not show any significant difference in expression of the total inactive non-phosphorylated protein between the different conditions (data not shown).
Relative quantitations to control cells were performed: first, each Ct value was corrected for the Ctr of the reference gene, GAPDH, and then the Ct of each sample was subtracted from the Ct of control cells (Ct0).
Further quantitation and quality control of total RNA samples were performed using a 2100 Bioanalyzer (Agilent Technologies).
Both total RNA and aRNA samples were analyzed on an Agilent 2100 Bioanalyzer for quantitation and quality control.
However, its cost (especially when heavy labelled internal standards are required for absolute quantitation) and quality control is sub-optimal for large cohorts.
We also confirmed the integrity of extracted RNA with the quantitation of internal control GAPDH mRNA and omitted two of the 256 samples in which GAPDH mRNA was undetectable in the training set (data not shown).
Quantitation and quality control were performed with a NanoDrop-1000 specThermo Fisher Scientificsher Scientific, Waltham, MA) and using the Quant-iT PicoGreen dsDNA Reagent (Life Technologies, Carlsbad, CA) in a Tecan GENios microplate reader (Tecan Group, Mannendorf, Switzerland).
