Invitrogen™ Molecular Probes™ NucRed™ Dead 647 ReadyProbes™ Reagent DFS Item

Cell impermeant stain that emits bright far-red fluorescence when bound to DNA

Manufacturer:  Invitrogen™ LSR37113

Catalog No. R37113



Includes: 6 x 2.5mL dropper bottles

Description

Description

  • Cells that have lost plasma membrane integrity are stained within minutes, making this extremely useful stain to estimate live/dead cell ratios and to measure cytotoxicity in kinetic live cell assays
  • Suitable for staining nuclei in fixed cell preparations and tissue section
  • Formulated as room temperature-stable solution and comes in convenient dropper bottle: tip and drip 2 drops/mL to stain cells, then incubate 15 to 30 minutes in most cases
  • Exceptionally bright far-red fluorescence upon binding to DNA
  • Rapid staining of damaged, dead, or fixed cells without wash steps
  • Ready-to-use liquid formulation: no need to dilute, weigh, or pipet
  • High-affinity DNA stain that easily stains cells with compromised cell membranes, yet does not enter living cells
  • Fluorescence increases several hundred-fold on binding to dsDNA in cells with compromised cell membranes (dying or dead cells), in fixed cells, and tissue slices
  • Spectral properties, with excitation/emission at 642/661nm when bound to DNA, is excellent for standard Cy5/Far Red filters
  • Long-wavelength fluorescence of the dye is well separated from that of commonly used fluorophores, such as Hoechst, GFP, Alexa Fluor™ 488, rhodamine (TRITC), Texas Red™ and many RFP variants
  • Well-suited for tissue staining, as its signal is generally not obscured by tissue autofluorescence
  • May be added directly to cells in full media or buffer solutions
  • In most cases, staining intensity increases with time if cells are not washed prior to imaging.
  • Excited with a maximum at 642nm when bound to DNA, with an emission maximum at 661nm
  • It is detected through far-red filters
