Figure 3From: Age-related changes in relative expression stability of commonly used housekeeping genes in selected porcine tissuesRanking of nine candidate reference genes using geNorm and NormFinder softwares . (a-d) geNorm ranks the candidate reference genes based on their stability parameter M. The lower the M value, the higher the expression stability. (e-h) NormFinder ranks the genes based on a calculated stability value. The lower the stability value, the higher the expression stability.Back to article page
