To further confirm that the IRE1-dependent splicing of xbp1 mRNA was induced by HTorAΔE, we used a xbp1-eGFP reporter that allowed eGFP to be expressed only when a 23 bp intron was spliced out of the xbp1-eGFP construct by IRE1 in the ER [ 31].

Normalized intensities were used as gene expression levels and genes were defined as being expressed only when their expression was higher than 99% quantile value of the expression of all negative control spots across all the arrays in this study (Figure 1a) as described by Zhang et al. [17].
