AM1-43 is a fixable, activity-dependent fluorescent nerve terminal probe. AM1-43 functions similarly similarly to SynaptoGreen (70020), but with the additional property of being fixable. Thus, AM1-43 is a useful tool for synapse studies where subsequent fluorescent immunochemistry is desired. AM1-43 and FM1-43 have identical excitation and emission wavelengths. Also see AM1-44 (catalog no. 70038), which is similar to AM1-43, but has longer lipophilic tails, resulting in better fixability.
