HM1-43 is a fixable, activity-dependent fluorescent nerve terminal probe. HM1-43 functions similarly to SynaptoGreen (70020), but with the additional property of being fixable. Thus, HM1-43 is a useful tool for synapse studies where subsequent fluorescent immunochemistry is desired. HM1-43 and FM1-43 have identical excitation and emission wavelengths.
