  • General notes

    DRAQ5™ is a cell permeable far-red fluorescent DNA dye that can be used in fixed or non-fixed/ live cells in combination with common labels such as GFP or FITC.

    As with any cell­-permeant DNA intercalating probe, DRAQ5 may inhibit cell division in long-term assays and should be tested for any effect.

    DRAQ5 staining can be used in flow cytometry, live cell imaging and cell-based assays and the dye is highly compatible with standard protocols across many instrumentation platforms.

    The chemical name of DRAQ5 is 1, 5-bis{[2-(di-methylamino)ethyl]amino}-4, 8-dihydroxyanthracene-9, 10-dione.

    The advantages of DRAQ5 staining include
    - convenient ready-to-use aqueous solution
    - rapid uptake into living cells, providing a high level of nuclear discrimination
    - no photobleaching effect
    - can be used in most cell types, eukaryotic and prokaryotic: mammalian, bacterial, parasitic, plant, etc.
    - no compensation needed with common FITC/GFP + PE combinations in flow cytometry
    - no RNase treatment required
    - no fluorescence enhancement upon DNA binding
    - compatible with optics of benchtop flow, laser scanning cytometers and non-UV laser scanning and lamp-based confocal microscopes

    SPECTRAL PROPERTIES:

    Excitation

    • 647 nm line optimal (Exmax 646 nm)
    • 488, 514, 568 and 633 nm lines, sub-optimal
    • Two-photon excitation (1047 nm) and excitation dark (700-850 nm)

    Emission (instrument dependent):
    - 665 nm to infra-red max 681 nm / 697 nm intercalated with dsDNA)
    - minimal overlap with vis range e.g. GFP and FITC
    - Em. filters may include 695L, 715LP or 780 LP

Applications

Our Abpromise guarantee covers the use of ab108410 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
FM Use at an assay dependent concentration.
Flow Cyt 1/1000 - 1/250. For Gating of Nucleated cells = 5µM; For Cell Cycle Analysis = 20µM
ICC/IF 1/1000. For Cell-based assays, Immunofluorescence microscopy and In-Cell WB = 5µM
It is highly recommended that the concentration and labelling conditions are carefully determined by each investigator for optimal performance in the assay of interest. For more specific information about the applications, please refer to the Protocol Booklet section.

DRAQ5: Cell cycle analysis with flow cytometry

Excellent Excellent 5/5 (Ease of Use)
Abreviews
DRAQ5 has been used with LNCaP C4-2B cell line in flow cytometry for cell cycle analysis. The cells were scraped and centrifuged for 5 min at 4C at 1.200 rpm. Washed with cold PBS and further centrifuged for 5 min at 4C at 1.200 rpm. The cells were then stained with 200 ul of staining solution (DRAQ5 1:1000 dil in PBS) for 1 h at room temperature protected from lighted. The reaction volume was finally made up to 500 ul and the cells were examined by flow cytometry. There is a distinct difference in the apoptotic induced treated cells with a high apoptoptic percentage (M1) and lower M2, M3 and M4 percentages, representing G1, S and G2-M phases, respectively.

DRAQ5 In cell Western As Part of an Ab Trial scheme

Excellent Excellent 5/5 (Ease of Use)
Abreviews
DRAQ5 has been used to normalize for cell number( C42B cell line) . DRAQ5, a DNA dye has been used to label nuclei, in 1:1000 dilution in PBS, with a total volume of 50µl/ well. The cells were incubated for 30 minutes at room temperature in dark, before scanning using appropriate excitation (648 nm) and emission (705LP) filters. Cell number titration has been performed using 60000, 30000, 15000 and 7500, respectively. The fluorescence intensity of each well was quantified using ImageJ and plotted in a graph using GraphPrism, as demonstrated in following figure .

DRAQ5 Abcam for In Cell Western Assay

Excellent Excellent 5/5 (Ease of Use)
Abreviews
Our lab uses DRAQ5 from Abcam for the In Cell Western Assay. DRAQ5 is used to provide accurate normalization over a broad range of cell densities. Specifically, it can be used for stoichiometric staining of DNA in live or fixed cells. DRAQ5 is used in the 700nm channel to normalize well-to well variation in cell number.
