Product overview

  • Name
  • Short description
    ER Stress inducer which induces cell death
  • Biological description

    Tunicamycin is an antibiotic which is commonly used to induce ER (endoplasmic reticulum) stress and activate the unfolded protein response (UPR) to induce cell death.

    Tunicamycin inhibits the DPAGT1 enzyme to inhibit one of the first steps of glycoprotein biosynthesis in the ER which results in the accumulation of misfolded proteins to cause subsequent ER stress.

    ER stress can often be induced by treating cells with tunicamycin at 2.5-5 µg/ml of tunicamycin for 5 hours.
