| Hazard Information | Back Directory | [Description]
IBTP is a lipophilic cation that is accumulated in mitochondria and forms stable thioether adducts in a thiol-specific manner.1 As a result, mitochondrial proteins that have changed thiol redox state following oxidative stress are selectively tagged with IBTP and can be separated by two-dimensional electrophoresis and isolated.1 IBTP-tagged proteins can also be evaluated by immunoblotting using an antibody directed against the triphenylphosphonium moiety of the IBTP molecule.2 IBTP has also been used as a mitochondria-targeted soft electrophile to inhibit mitochondrial oxidative phosphorylation.3 | [Uses]
IBTP iodide is a lipophilic cation and can be accumulated by mitochondria and yields stable thioether adducts in a thiol-specific
reaction. IBTP iodide can be used for specific labeling of mitochondrial protein thiols[1]. | [storage]
