Figure 1From: Selection of reference genes for quantitative real-time PCR in equine in vivo and fresh and frozen-thawed in vitro blastocystsAverage expression stability values of equine in vivo and in vitro embryos. The average stability values of the control genes were calculated with geNorm. When in vivo embryos and fresh and frozen-thawed in vitro embryos were combined, UBC, ACTB, RPL32 and GAPDH were found to be the most stable.Back to article page
