  • The Sensitive EdU Cell Proliferation Kits combine all the advantages of their very popular predecessors – the EdU Cell Proliferation Kits – with a brand new fluorescence enhancer system. This makes them just as easy to handle and as reliable, while showing outstanding efficiency and greatly enhanced signal and sensitivity.

    Profit from:

    » Exceptional sensitivity and enhanced fluorescence signals
    » Lower copper concentrations needed
    » Better signal-to-noise ratio
    » Optimized for low content HTS and Flow Cytometry analysis

    We offer these Sensitive EdU Cell Proliferation Kits for three different ranges of application: cell proliferation analysis by imaging (IM), by flow cytometry (FC) and by high throughput screening analysis (HTS). For detection in fluorescent microscopy imaging and flow cytometry, the Eterneon2-488 Dye Azide (FITC alternative) and the Eterneon2-647 Dye Azide (Cy5 Azide alternative), for HTS applications the Eterneon2-488 Dye Azide and the Eterneon2-555 Dye Azide (TAMRA alternative) are offered.


    • What type of cells can incorporate EdU?

      The EdU cell proliferation assay has been applied to many different cell types and organism. Cancer cell lines like HeLa, HEK, MOLM are arguably among the most routine applications, but also animals, like mouse, rat, the nematode C. elegans, crickets (Gryllus bimaculatus), chicken (Gallus domesticus) and zebra fish (Danio rerio) or even plants (e.g. Arabidopsis thaliana) can be applied.
      Cells that possess a pyrimidine salvage pathway can phosphorylate EdU to the corresponding triphosphate, which is then accepted by the host DNA polymerase for incorporation into DNA during replication and therefore they are compatible with the EdU assay.

    • Can I perform EdU cell proliferation detection on live cells?

      No, at the moment the kit needs live cells to incorporate the EdU, but the detection reaction must be performed on fixed and permeabilized samples. The click cocktail is cell impermeant.

    • How does EdU labeling compare to BrdU or the 3H-thymidine incorporation assay?

      All three methods enable to determine cell proliferation directly, by incorporation of a metabolite analogue and subsequent detection. The 3H-thymidine incorporation assay is very sensitive, but the radioactive compound requires specialized equipment and dedicated lab space for handling. EdU and BrdU assays are non-radioactive alternatives with decreased risk for health and environment. Compared to the BrdU incorporation assay the EdU assay is more sensitive, requires less handling time and needs no harsh DNA denaturing conditions for detection. Therefore, the EdU cell proliferation is also compatible with multiplexing.

    • Can I combine DAPI staining and EdU detection?

      Yes, this is feasible. Please note that DAPI staining should be done after the click detection step. Alternatively, SYBR Green DNA staining can be used. But, please note that SYBR green is not compatible with the 488 EdU kits.

    • When can I stop safely the protocol?

      It is possible to safely stop the protocol after the fixation step, remove the fixation solution and wash as suggested by the user manual, then the cells can be stored in buffer at 4° C, the permeabilization step is not required immediately. The protocol can be safely stopped even after the permeabilization, following the same recommendation as before.
      It is important to not stop the protocol if the click cocktail for the detection of the EdU has been prepared, since the cocktail reacts optimally within 15 minutes.

    • Is antibody staining compatible with the EdU?

      Antibody staining is compatible with EdU cell proliferation detection when antibody detection is done after the click detection step. Please make sure that the detection signals of both detection methods do not overlap due to identical or similar spectral properties of the dyes. Check also the user manual for more information.

    • What is the right duration of EdU incubation?

      The duration of the EdU incubation step depends on your cell type or organism, the applied EdU concentration and even the experimental design. For a start it is advisable to refer to a published protocol (which is close to your experimental setup) and to test the conditions with a low number of samples. As a general guideline we recommend to use a maximum of 10 µM final EdU in the cell culture medium for incubations of a few hours to maximum one day. For longer incubation durations the concentration should be decreased to 1-5 µM. Cells that divide rapidly (once a day) generally require shorter incubation compared to cells with slow division (once a week).
