Description:
Useful as a fluorescent stain for heparin in several cell lines.
Application:
An effector for MDR (multidrug resistance)efflux pumps and is potentiated by the MDR inhibitor 5'-methoxyhydnocarpin (5'-MHC). Treatment with berberine potentially results in the reduced accumulation of chemotherapeutic drugs. Berberine upregulates the expression of Pgp in hepatoma cells.
