Fig. 2. hFBNRG3 is expressed in the human foetal brain. RT-PCR was used to detect mRNA expression in the human foetal tissues. An amplicon of the expected size was obtained from human foetal brain but not from other foetal tissues (top). The molecular identity of the amplicon was verified after its cloning and sequencing. Quality of cDNA synthesis was checked by amplifying the housekeeping gene ß-actin (bottom).
