    AM4-66

    From: $225 Sizes: 1 mgCatalog #: 70050

    AM4-66 is a fixable red fluorescent nerve terminal probe. The dye is spectrally identical to SynaptoRed C2 (also called FM4-64), but it has an additional amine group at the hydrophilic end of the molecule, making the dye fixable with formaldehyde or gluteraldehyde.

    RH795

    From: $193 Sizes: 5 mgCatalog #: 61019

    The styryl dye RH795 is a fast-responding potentiometric probe that is primarily used for functional imaging of neurons. The dye is spectrally similar to RH414 (61016), but exhibits different physiological effects during staining. For example, RH414 causes arterial constriction during cortex staining, while RH795 does not (see references 1,2).
