The advantage of absolute quantification in comparative hormone research as indicated by a newly established real-time RT-PCR: GH, IGF-I, and IGF-II gene expression in the tilapia, Oreochromis niloticus


Eppler, E; Caelers, A; Berishvili, G; Reinecke, M (2005). The advantage of absolute quantification in comparative hormone research as indicated by a newly established real-time RT-PCR: GH, IGF-I, and IGF-II gene expression in the tilapia, Oreochromis niloticus. Annals of the New York Academy of Sciences, 1040(Trends in ):301-304.

Abstract

We have developed a real-time RT-PCR that absolutely quantifies the gene expression of hormones using the standard curve method. The method avoids cloning procedures by using primer extension to create templates containing a T7 promoter gene sequence. It is rapid since neither separate reverse transcriptions nor postamplification steps are necessary, and its low detection level (2 pg/mug total RNA) allows precise absolute quantification. Using the method, we have quantified the gene expression of GH, IGF-I, and IGF-II in the tilapia.
