Delta Ct values for 77 OR genes. Results of RTqPCR (means of technical triplicate for each gene), are expressed as delta Ct values (Cycle threshold), using Hprt mRNA as a reference (Ct OR-Ct Hprt). The analyses were performed on three samples and the size of the vertical bars corresponds to the standard deviation. The curve links the mean Ct values obtained with these three samples. The name of the OR genes are indicated on the x axis: in green are genes identified as expressed, in yellow the OR genes identified as weakly expressed and in red are the OR genes identified as not expressed by microarray hybridization. As indicated by the size of the vertical bars defining the cycle threshold (Ct) values for any given analyzed RNA, the amount of mRNA differs by 0.08 to 2.2 Ct between the three samples.
