From: Selection of reliable reference genes for qPCR studies on chondroprotective action
qPCR cycle threshold values of 6 reference genes among 7 culture conditions (table 2). Distribution of expression levels of ACTB, GAPDH, B2M, HPRT1, SDHA, and YWHAZ in IL-1β treated C-28/I2 chondrocytes under the influence of glucosamine (A), curcumin (B) and diacerein (C) is shown as medians (lines), 25th percentile to the 75th percentile (boxes) and ranges (whiskers) (n = 63). Samples were normalized to the amount of total RNA.
