Fig. 1From: Evaluation of reference genes for RT-qPCR study in abalone Haliotis discus hannai during heavy metal overload stressRepresentative end-point gel showing the specific amplification of the single PCR band for each of 12 candidate reference genes tested in this study. PCR products were run on 2 % agarose gel and visualized by ethidium-bromide staining. The description for each gene symbol can be referred to in Table 1 Back to article page
