However relative quantification of gene expression using qRT-PCR is highly influenced by the expression stability of internal control or reference genes used for transcript normalization of target genes. The use of inappropriate or unstable reference gene(s) can seriously impact the transcript quantification results leading to false inferences or misinterpretations21‚22. Accurate normalization is thus necessary for obtaining biologically meaningful expression data and hence qRT-PCR analysis greatly
