Assay: IRE-1alpha Assay: A fusion protein comprising glutathione S transferase (GST) and human IRE-1α (GST-IRE-1α) obtained from a 500 ml baculovirus-infected insect cell culture can be used to measure IRE-1α activity in vitro. Five μl of a reaction mixture comprising 1× reaction buffer (5× reaction buffer is 100 mM Hepes pH 7.5, 250 mM KOAc, 2.5 mM MgCl2), 3 mM DTT, and 0.4% polyethylene glycol water is added to each well of 384 well plates. Twenty-five nanoliters of a 1 mM test compound solution are added to test wells. Three μl of a 128 ng/ml IRE-1α preparation are added to each test well and to positive control wells (final concentration 5.82 ng/well). Negative control wells contain only reaction mixture and test compound. After spinning the plates at 1200 rpm for 30 seconds, 3 μl of an IRE-1α human mini-XBP-1 mRNA stem-loop substrate 5'-CAGUCCGCAGCACUG-3' (SEQ ID NO:1), labeled with the fluorescent dye Cy5 at the 5' end and Black Hole Quencher 2 (BH2) at the 3' end, are added to each well of a control plate. The plates are again spun at 1200 rpm for 30 seconds. Final concentrations for the assay are: 63 nM IRE-1α substrate, 5.82 ng IRE-1α protein, and 2.5 μM test compound. The plates are covered with lids and incubated for one hour at 30° C. The plates are then transferred to an ACQUEST™ microplate reader. Data is analyzed using data analysis software, and the percent activity of IRE-1α is calculated.

The plates are again spun at 1200 rpm for 30 seconds. Final concentrations for the assay are: 63 nM IRE-1α substrate, 5.82 ng IRE-1α protein, and 2.5 μM test compound. The plates are covered with lids and incubated for one hour at 30° C. The plates are then transferred to an ACQUEST™ microplate reader. Data is analyzed using data analysis software, and the percent activity of IRE-1α is calculated.

The plates are covered with lids and incubated for one hour at 30° C. The plates are then transferred to an ACQUEST™ microplate reader. Data is analyzed using data analysis software, and the percent activity of IRE-1α is calculated.

Assay: IRE-1alpha Assay: A fusion protein comprising glutathione S transferase (GST) and human IRE-1α (GST-IRE-1α) obtained from a 500 ml baculovirus-infected insect cell culture can be used to measure IRE-1α activity in vitro. Five μl of a reaction mixture comprising 1× reaction buffer (5× reaction buffer is 100 mM Hepes pH 7.5, 250 mM KOAc, 2.5 mM MgCl2), 3 mM DTT, and 0.4% polyethylene glycol water is added to each well of 384 well plates. Twenty-five nanoliters of a 1 mM test compound solution are added to test wells. Three μl of a 128 ng/ml IRE-1α preparation are added to each test well and to positive control wells (final concentration 5.82 ng/well). Negative control wells contain only reaction mixture and test compound. After spinning the plates at 1200 rpm for 30 seconds, 3 μl of an IRE-1α human mini-XBP-1 mRNA stem-loop substrate 5'-CAGUCCGCAGCACUG-3' (SEQ ID NO:1), labeled with the fluorescent dye Cy5 at the 5' end and Black Hole Quencher 2 (BH2) at the 3' end, are added to each well of a control plate.
