Induction of SNAP-23 in Ba/F3 cells and Ba/F3 transfectants. Factor- and serum-starved Ba/F3 cells and Ba/F3 transfectants were stimulated with mIL-3 and hGM-CSF for the indicated time (h), respectively. Poly(A)⁺ RNA (1 μg/lane) was extracted from the cells and blotted with SNAP-23 and G3PDH probes.
