Description

When unfolded proteins accumulate in the ER lumen, multiple unfolded protein response (UPR) pathways become activated, including PERK, ATF6, and IRE1α, all of which transcriptionally reprogram the flux of proteins through the ER. When these quality control mechanisms fail to restore ER homeostasis, sustained stress results in the induction of CHOP, a pro-apoptotic transcription factor that negatively regulates expression of BCL2 and increases expression of BIM and TNFS10RB. One mechanism cancer cells exploit to adapt to harsh conditions of the tumor microenvironment is through upregulation of UPR pathways. Thus, understanding the molecular mechanisms that govern the switch from adaptation to apoptosis is of great therapeutic interest.

Application

ICFC - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633 nm / 635 nm.

Application Notes

This clone failed to detect CHOP in human small intestine.

For ICC testing, we do not recommend methanol only as a fixation-permeabilization step due to poor CHOP staining. We recommend 4% PFA fixation with either Triton X-100 or methanol permeabilization.
