Figure 3. Inhibition of XBP1 splicing correlates with the amount of XBP1S.
XBP1 splice assay of cDNA from CHO-S XB cells induced for 3 days with a range of doxycycline (Dox) concentrations, either not treated with tunicamycin (Tn) ( A, C), or treated with 10µg/mL Tn for 3 h. Primers specific for endogenous XBP1 ( A, B) or endogenous and exogenous XBP1 ( C) were used. The experiment was performed twice, data from a representative experiment is shown.
