Northern blots analysis of ovarian carcinoma- and placenta-derived total RNA samples (2 µg and 10 µg per lane) hybridized with [32P]-labeled thyrotropin receptor (TSHR) and human placental lactogen (hPL) cDNA probes. Comparison with the array hybridization signatures obtained at the respective spot locations (open circles) on corresponding membranes (AMMAIN4 and AMMAIN5) show consistent agreement with revealing differences in transcript abundance between the two tissue samples.
