MagDot 420

MagDot 420 (Ex-Max 300 nm/Em-Max 420 nm)

MagDot 420 is a nanoparticle optimally excited from 320 nm to 405 nm with an emission peak at 420 nm. This dye is part of Core Quantum Technologies' MagDot product line. Each MagDot consists of both quantum dots and magnetic iron oxides in the same particle. This allows for magnetic separation/ enrichment of targeted cells for downstream flow cytometric analysis or an application using electron microscopy.
