FIG. 3.
Northern blot analysis of Mx2 expression. Each lane contained 20 μg of total RNA isolated from embryonic cells. Embryonic cells were treated with 500 IU of IFN-α/β per ml for 18 h or were left untreated. The Mx2 cDNA (top) was used as a probe and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) cDNA (bottom) was used as a control for the probe.
