MultiDot 520
MultiDot 520 is a green emitting fluorophore optimally excited at 350 nm with an emission peak at 520 nm. This dye is part of Core Quantum Technologies' MultiDot product line. Each MultiDot consists of several quantum dots with a patented coating, resulting in increased sensitivity and a tighter emission spectrum which limits spectral overlap.
