Figure 1From: Selection of ovine housekeeping genes for normalisation by real-time RT-PCR; analysis of PrPgene expression and genetic susceptibility to scrapiePrP gene expression levels in the different tissues of 22 sheep grouped in risk groups. The PrP mRNA levels were obtained by relative quantification real-time RT-PCR analysis using the most stable HK genes within each tissue. Error bars represent standard deviation. Risk groups according to the NSP classification [7].Back to article page
