Spark PLUS YG581

Spark PLUS YG581™ from Biolegend is a fluorophore for use in both conventional and spectral flow cytometry with an excitation peak at 561 nm and an emission peak at 585 nm. It has minimal cross-laser excitation with the 488 nm laser, which makes it distinguishable from PE. In addition to PE, it can be unmixed from colors like Brilliant Violet 605™, PE/Dazzle™ 594, and FITC, which makes it a good option for large spectral panels.
