Figure 2From: Internal control genes for quantitative RT-PCR expression analysis in mouse osteoblasts, osteoclasts and macrophagesDistribution of qPCR cycle threshold values for the candidate reference genes. The expression of 18S, ACTB, B2M, GAPDH, HMBS and HPRT1 candidate internal control genes in osteoblasts (A), macrophages (B) and osteoclasts (C) are presented as box and whisker plots. Circles and asterisks represent outliers.Back to article page
