1、锦鲫Clock基因表达量分析中的内参基因稳定性比较 摘要为研究锦鲫Clock基因表达量分析中的内参基因稳定性,采用qRTPCR技术进行实时荧光定量分析,并用GeNorm和NormFinder软件对5个内参基因(RPL13,GAPDH,18SrRNA,βactin和RPS29)进行稳定性评估,筛选出不同组织中最适合的内参基因,以准确定量Clock基因的相对表达水平.实验结果表明,5个内参基因中,18SrRNA在锦鲫的肌肉、心脏、肝脏中表达最稳定,βactin在肠中表达最稳定,RPL13在肾中表达最稳定;根据筛选的内参基因定量Clock基因的相对表达水平发现,Clock基因在锦鲫肌肉中相对表
