Reversible inhibitor of protein translocation from the endoplasmic reticulum (ER) to the Golgi apparatus. Blocks binding of ADP-ribosylation factor to the Golgi apparatus and inhibits GDP-GTP exchange. 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). Purity 98%. MW (observed): 280.36
