Invitrogen™ LIVE/DEAD™ Fixable Red Dead Cell Stain Kit, for 488 nm excitation

Description

• Used to determine the viability of cells prior to the fixation and permeabilization required for intracellular antibody staining or prior to elimination of biohazardous materials using formaldehyde fixation
• Kit has been optimized and validated for use with a blue laser flow cytometer
• Conveniently packaged in 40-test vials to help ensure the stability and performance of the dye over time
• Amine reactive dyes in solution will lose their effectiveness over a short period of time, therefore it is recommended to completely use the vial once rehydrated
• If this is not possible, aliquot the vials in small volumes and store at -80°C, avoiding freeze-thaw cycles
• LIVE/DEAD™ Fixable Dead Cell Stains are available in a wide variety of colors to meet multi-color panel needs

Optimal brightness

• The LIVE/DEAD™ Fixable Red stain was selected based on its fluorescent properties to provide a bright signal when excited with a yellow, green, or blue 488 nm laser
• The red-fluorescent reactive dye has an excitation maximum of ∼595 nm, making it ideal for use with the yellow laser, and an emission of ∼615 nm, allowing collection in the 610 or 630 BP filter
• LIVE/DEAD™ Fixable Red Dead Cell stain is also excited well with the blue 488 nm laser
• Since live and dead cells can be discriminated using a single dye and a single channel of a flow cytometer, it is an ideal choice for multi-color experiments
