Cell Staining

EviTag Quantum Dot Labels and EviFluor quantum dot conjugates have been successfully introduced into live, fixed and permeabilized cells. They have been used to preferentially stain the cytoskeleton, centromeres and kinetocores, and other organelles as well as track the evolution of growth of frog and nematode embryos. Due to the unprecedented photostability and color multiplexing properties, continuous observations using fluorescence and confocal microscopes of multiple cellular components and cellular metabolism/transport can be made over a period of hours to days.
