"Figure 4. The 3′ end of βG-Δi is required for nuclear retention. (A) A schematic representation of the different constructs that were used in this figure. (B–E) Plasmids containing the indicated constructs were transfected into human U2OS cells. After 14–18 h, the cells were fixed, permeabilized, and stained for mRNA using a FISH probe directed against the MHC SSCR (B,C) or βG (D,E). The cells were imaged (B,D) and mRNA distribution was quantified (C,E). Each bar represents the average and standard error of three independent experiments, each experiment consisting of at least 30 cells. Scale bar = 20 µm."
