Abstract: | Background Quantitative real-time PCR (qPCR) has been the method of choice for the quantification of mRNA. Due to the various artifactual
factors that may affect the accuracy of qPCR, internal reference genes are most often used to normalize qPCR data. Recently,
many studies have employed computer programs such as GeNorm, BestKeeper and NormFinder in selecting reference genes, but very few statistically validate the outcomes of these programs. Thus, in this study, we
selected reference genes for qPCR of liver and ovary samples of yellow (juvenile), migratory (silver) and 11-KT treated juveniles
of New Zealand shortfinned eels (Anguilla australis) using the three computer programs and validate the selected genes statistically using REST 2009 software and the Mann-Whitney test. We also tested for the repeatability of use for the best reference genes by applying
them to a data set obtained in a similar experiment conducted the previous year. |
