Assessment of cell death studies by monitoring hydrogen peroxide in cell culture.

Hydrogen peroxide (H2O2) has been widely used to study the oxidative stress response. However, H2O2 is unstable and easily decomposes into H2O and O2. Consequently, a wide range of exposure times and treatment concentrations has been described in the literature.

ERp29 deficiency affects sensitivity to apoptosis via impairment of the ATF6-CHOP pathway of stress response.

Endoplasmic reticulum protein 29 (ERp29) belongs to the redox-inactive PDI-Dβ-subfamily of PDI-proteins. ERp29 is expressed in all mammalian tissues examined. Especially high levels of expression were observed in secretory tissues and in some tumors.
