Northern blot analysis. (A) Five micrograms of Poly(A) RNA from uninduced (1) and induced (2) U937 cells. (B) Northern blot containing 20 μg of total RNA from human tissues was obtained from Clonetech. (C) Five micrograms of Poly(A) RNA from different cell lines. Each blot was hybridized with a full-length [32P]-labeled Emp cDNA probe. Blot A was stripped and reprobed with human β-actin cDNA. The size of the markers in kilobases is shown.
