Figure 1From: Evaluation of reference genes in mouse preimplantation embryos for gene expression studies using real-time quantitative RT-PCR (RT-qPCR)Transcript levels of selected reference genes in the ICR mouse-derived preimplantation stage embryos. Transcription levels of ten housekeeping genes shown for KSOM- (A), CZB- (B), M16- (C), and in vivo (D)-derived embryos. The mRNA expression level at zygote stage was measured as a control to calculate the relative amounts in the different stages.Back to article page
