We named our products after their peak emission wavelength when they are bound to their target. That means, when Amytracker™480 is bound to amyloids, it will emit blue flourescence that you can see with a standard DAPI filter set. Amytracker™515 appears green when bound to amyloids and we recommend a standard FITC filter set for imaging. Amytracker™545 is yellow and you can choose between the standard FITC or TRITC filter sets to image your amyloid staining. Our red Amytracker™680 can be imaged with the Cy5 filter set when its bound to amyloids.
