TBP and colitis: Finally, among 13 candidate reference genes, a combination of EEF2/TBP (geNorm) was proposed as a reference gene for fresh colon samples of DSS-treated male C57BL/6 mice [7], while for archived FFPE colon samples of DSS-treated C57BL/6 mice of both sexes, with various phases of the disease/colitis and inter/intra-experimental variability involved, the combination of EEF2/RPLP0 (NormFinder) was proposed as a robust reference gene.
