• 产品描述： 4μ8C(IC50=76 nM) is an effective and specific IRE1 Rnase inhibitor.

• 靶点： IRE1

• 体内研究：
  4μ8C reverses the ER stress-dependent loss of several known RIDD targets, with an EC50 of approximately 4 μM, approximating that of inhibition of XBP1 target gene activation

• 细胞实验： Cells are seeded in phenol red-free cell culture medium in 96 or 24 well dishes at a density of 5 × 103 or 5 × 104 cells per well, respectively. Cultures are incubated for 16 h before treatment with 4μ8C for 24 h. Cultures are then analyzed by the addition of 200 μM WST1 and 10 μM phenazine metho-sulfate. After development of the reagent for 2 h at 37°C, the hydrolyzed dye is detected by absorbance at 450 nm, after subtracting background and absorbance at 595 nm. Alternatively, cell viability is determined by staining of the adherent culture with crystal violet. Quantitation of the dye uptake is analyzed by extensive washing of the stained cells with water and solublization of the crystal violet in methanol followed by absorbance measurements at 595 nm.
