Product Description
CHOP Control Cell Extracts (C2C12 Untreated): Total cell extracts from C2C12 cells serve as a negative control. Supplied in SDS Sample Buffer.
CHOP Control Cell Extracts (C2C12 +Thapsigargin): Total cell extracts from C2C12 cells treated with thapsigargin (300 nM, 2 hr) serve as a positive control.
This lysate pair is produced as a control for western blotting of CHOP and other ER Stress proteins.

Background
CHOP was identified as a C/EBP-homologous protein that inhibits C/EBP and LAP in a dominant-negative manner (1). CHOP expression is induced by certain cellular stresses including starvation and the induced CHOP suppresses cell cycle progression from G1 to S phase (2). Later it was shown that, during ER stress, the level of CHOP expression is elevated and CHOP functions to mediate programmed cell death (3). Studies also found that CHOP mediates the activation of GADD34 and Ero1-Lα expression during ER stress. GADD34 in turn dephosphorylates phospho-Ser51 of eIF2α thereby stimulating protein synthesis. Ero1-Lα promotes oxidative stress inside the endoplasmic reticulum (ER) (4). The role of CHOP in the programmed cell death of ER-stressed cells is correlated with its role promoting protein synthesis and oxidative stress inside the ER (4).
