Brefeldin A

Key Product Details

Product Description

Brefeldin A is a reversible inhibitor of protein translocation from the endoplasmic reticulum (ER) to the Golgi apparatus. Blocks binding of ADP-ribosylation factor (ARF1) to the Golgi apparatus and inhibits GDP-GTP exchange, leading to activation of ER stress signaling pathways. Can be used to induce autophagy in mammalian cells. Also enhances CRISPR-mediated homology-directed repair (HDR) efficiency ~2-fold when applied at 100 nM, in human induced pluripotent stem cells (iPSCs). Antifungal.
