Leu-Leu-OMe HBr
Lysosomal damaging agent / Leu-Leu-OMe is a lysosomal damaging agent (lysosomotropic). It is condensed into a membranolytic polymer via the transpeptidase action of cathepsin C within lysosomes.1,2 May be used to induce a lysosomal damage model in cells.3,4 LLOMe-induced lysosomal damage elicits ubiquitin puncta formation on lysosomes1. Induces apoptosis in human mast cells via lysosome destabilization leaving fibroblasts and HEK-293 cells largely resistant5. Induces lysophagy.4
