In this study, the relative abundance of splicing variants of Oreochromis non-NMDA subtype glutamate receptors was studied by quantitative reverse-transcriptase PCR (RT-PCR). The relative expression level between the flip and flop transcripts of fGluR2α determined by quantitative RT-PCR is apparently much higher than that estimated by sequence analysis of the cloned RT-PCR products. Control studies were performed to demonstrate the accuracy of the application of quantitative RT-PCR analysis in studying the relative abundance between the flip and flop transcripts of glutamate receptors.
