Figure 1From: Validation of suitable house keeping genes for hypoxia-cultured human chondrocytesExpression of ANKRD37 (A) SOX9 (B). Relative mean expression is presented on day 1, 2, and 6 in human chondrocytes cultured in 21%, 5% or 1% oxygen (error bars: SEM). RPL13A and B2M are used as reference genes. Values for each sample are normalized to baseline expression.Back to article page
