Fixable Viability Dye 448

Fixable Viability Dye 448 is excited by the UV laser (with an excitation maximum of 350 nm) and has fluorescence emission maximum at 448 nm, Fixable Viability Dye 448 has similar emission to DAPI.

Fixable Viability Dye 448 can intracellular diffusion of the dye and covalent binding to higher overall concentrations of amines, each lot of this product is quality control tested, is useful for discrimination of viable from non-viable mammalian cells in multicolor flow cytometric applications.

Each lot of this product is quality control tested. The labeled cells can be fixed with formaldehyde for downstream decontamination, freezing and/or permeabilization and subsequent intracellular staining while maintaining stable viability stain fluorescence.
