The principle of DPA/Tb 3 for vesicle fusion assay is based on the fact that contact of the chelator dipicolinic acid (DPA) with terbium (III) forms an instant Tb 3 -DPA complex that is ~ 10,000 times more fluorescent than free Tb 3 . In the assay, separate vesicle populations are loaded with 2.5 mM...

AM4-65 is a fixable red fluorescent nerve terminal probe. The dye is spectrally identical to SynaptoRed™ C2 (equivalent to FM®4-64), but it has an additional amine group at the hydrophilic end of the molecule, making the dye fixable with formaldehyde or gluteraldehyde. The long emission wavelength...

Ponceau S is used for the detection of proteins on PVDF and nitrocellulose membranes with a limit of detection of about 250 ng of transferred protein. The dye rapidly stains proteins on membranes pink or light red for easy visual inspection of protein transfer. The staining is reversible and...
