Invitrogen™ LIVE/DEAD™ Fixable Near-IR Dead Cell Stain Kit, for 633 or 635 nm excitation

Descrizione

• 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 red 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 Near-IR stain was selected based on its fluorescent properties to provide a bright signal when excited with a red laser
• The near-IR fluorescent reactive dye has an excitation maximum of ∼633 nm making it ideal for use with the red or HeNe laser with an emission of ∼750 nm
• 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
