Catalog Number: 3400
Chemical Name: (bis(2,2'-Bipyridine-N,N')triphenylphosphine)-4-aminobutyric acid ruthenium hexafluorophosphate complex
Biological Activity
Ruthenium-bipyridine-triphenylphosphine caged GABA (Cat. No. 0344) that is excited by visible wavelengths. Provides greater tissue penetration, less phototoxicity, faster photorelease kinetics and better spatial resolution than UV light-sensitive caged compounds. Produces GABA receptor-mediated currents in pyramidal neurons in vitro and displays no effect on endogenous GABAergic or glutamatergic transmission at concentrations effective for uncaging.
