Induction of SNAP-23 message by stimulation with IL-3/GM-CSF/IL-5 in factor-dependent cells. OTT-1 and L-GM3 cells were deprived of serum and mIL-3 for 6 hours, then stimulated with IL-3/GM-CSF/IL-5 for the indicated periods (h). Poly(A)⁺RNA (2 μg/lane) was separated from the cells and blotted with SNAP-23 and G3PDH probes.
