Northern blot analysis.
Ten micrograms of total RNA sample were electrophoresed on agarose formaldehyde gels and transferred onto nylon membranes. The blots were hybridized with [α-32P] dCTP-labeled cDNA probes at 65°C overnight using a standard method. Filters were rinsed to a final stringency of 0.25 × SSC and exposed to a Kodak X-Omat or a Biomax film at -70 °C with an intensifying screen. After sequential stripping of the probes by a standard method, the blot was rehybridized with a GAPDH probe as a control.
