Expression of CK2β protein. A549 cells were transfected with either control or CK2β siRNA. (a) Total amount of CK2β protein detected at 24 h, 48 h, and 72 h post-transfection (p.t.) by Western blot analysis with a mAb specific for the β-subunit of CK2. Loading was controlled with a mAb against β-actin. (b) Total CK2α protein detected 24 h, 48 h, and 72 h after transfection with CK2β siRNA.
