Amytracker 680

Amytracker 680 is our red optotracer for labeling protein aggregates with repetitive arrangement of β-sheets. It labels Aβ plaques and neurofibrillary tangles in tissue sections with AD pathology and α-synuclein aggregates in tissue sections with PD pathology. Specifically, Amytracker 680 has been used to study amyloid formation during abnormal coagulation, Lewy body formation in a seeding based neuronal model, accumulation of misfolded proteins in the nucleolus and intracerebral formation of Aβ plaques using multiphoton microscopy.

As all our optotracers, Amytracker 680 is exceptionally photostable and fluorogenic. When bound to a target, Amytracker 680 can be imaged using epifluorescence, confocal and superresolution microscopy. Spectral information can be acquired using a fluorescence spectrophotometer. Use recommended filter sets as well as excitation- and emission wavelengths according to the following table.

Amytracker 680 is available in four different formulations (See volumes and prices in the drop-down list below): 

• Aqueous: 1 mg/ml solution in ultrapure water. The product should be diluted 1:1000 before use. For use in live-cells, sometimes 1:500 is necessary due to uptake limitations. To prevent evaporation of the aqueous solvent, close the container carefully after use, spin down liquid and use up small volumes quickly.
• DMSO: 1 mg/ml solution in DMSO to prevent solvent evaporation. The product should be diluted 1:1000 before use. For use in live-cells, sometimes 1:500 is necessary due to uptake limitations.
• Solid: 1 mg solid lyophilised in a sterile injection bottle. We recommend dilution to 4 mg/ml in physiological saline followed by intravenous injection with a total dose of 5 mg/KG.
• Drop&Shine: 5 ml ready-to-use product in mounting medium. Ideal for use in tissue sections. Add a some Drop&Shine and mount your slide to detect amyloids within minutes.
