A qRT-PCR reaction for the exogenous RCP1 control gene was performed to allow for standardization of expression of the CF genes by accounting for differences between samples in the RT reactions.

We were able to identify eight genes (ALB, B4GALT6, GAPDH, HMBS, YWHAZ, ABCA5, ABCA9, and ABCC1) which demonstrated no altered gene expression levels in all tested conditions and therefore represent good candidates for the standardization of gene expression studies in altered gravity.
Another important point for future studies is standardization of NKLR expression, for example by normalization according to standard cells, or by employment of a different method such as quantitative real time PCR.
Standardization of gene expression data from three biological replicates was performed as described [ 74].
Briefly, standardization of gene expression data was performed from three biological replicates as described [ 106].
For standardization of gene expression levels, mRNA ratios relative to RP29 as housekeeping gene were calculated, and real-time quantitative data were analyzed using the ΔΔCt method.
After standardization of the expression values from the different time points, clustering by complete linkage based on centered correlation was carried out.
Each sample was tested in triplicate with quantitative PCR and, for standardization of gene expression levels, mRNA ratios relative to the house-keeping gene GAPDH were calculated.
We conclude that such prototype reference panels could be useful QC materials for the standardization of gene expression measurements between laboratories and platforms, and in aiding interpretation of biomarker profiling data in regulatory settings.
Standardization of the expression of 12-LOX in platelet-rich plasma to the concentration of TGB and the number of PLT significantly increases the sensitivity of the test and could be used as biomarker for the assessment of risk for the prostate cancer.
