Click-iT Plus EdU Cell Proliferation imaging kits have been optimized for fluorescence microscopy applications and are a superior alternative to traditional proliferation assays. In this assay the modified thymidine analogue EdU (5-ethynyl-2'-deoxyuridine, a nucleoside analog of thymidine) is efficiently incorporated into newly synthesized DNA and fluorescently labeled with a bright, photostable Alexa Fluor™ dye in a fast, highly-specific, mild click reaction.

• Simple—works the first time, every time, in less time than traditional methods
• Efficient—no denaturation steps or harsh treatment required
• Content-rich results—improved preservation of cell morphology, antigen structure, GFP fluorescent signal, and DNA integrity
• Consistent—not dependent on variable antibody lots for detection

The kit contains all of the components needed to label and detect the incorporated EdU as well as perform cell cycle analysis on samples from adherent cells. For cell cycle analysis, the kit includes a blue fluorescent Hoechst 33342 dye. The kit contains sufficient reagents for labeling 50 18x18 coverslips using 500 μL of reaction buffer per test.

Avoid the Harsh Treatments Associated with BrdU Method
Measuring changes to cell proliferation is a fundamental method for assessing cell health, determining genotoxicity, and evaluating anti-cancer drugs. The most accurate method of doing this is by directly measuring DNA synthesis. The traditional method utilizes the nucleoside analog BrdU (5-bromo-2'-deoxyuridine, a nucleoside analog of thymidine), which is incorporated into newly transcribed DNA. After incorporation the samples are treated with harsh methods (HCl, heat, or enzymes) to denature the DNA and expose the BrdU molecules to detection by anti-BrdU antibodies. However, the BrdU method to measure cell proliferation is time consuming and difficult to perform consistently. The harsh treatments necessary for this method can adversely affect sample integrity, cell morphology, image quality, and the ability to multiplex.

The Click-iT™ Plus EdU assay measures the rate of new DNA synthesis based on incorporation of the nucleoside analog EdU into DNA. Detection is achieved through a catalyzed 'click' reaction that is completed typically within 30 minutes. The click reaction uses bioorthogonal (biologically unique) moieties to fluorescently label proliferating cells, producing low backgrounds and high detection sensitivities. Because of the mild reaction conditions the Click-iT™ Plus assays can accurately determine cell proliferation while preserving cell morphology, DNA integrity, antigen binding sites, and the fluorescent signal from GFP. Preservation of DNA integrity allows for DNA staining, including staining with dyes used for cell cycle analysis.

    Frequently asked questions (FAQs)

    What are the main characteristics of a Click-iT reaction?

    Click reactions have several general characteristics: the reaction is efficient, no extreme temperatures or solvents are required, the reaction is complete within 30 minutes, the components of the reaction are bio-inert, and perhaps most importantly, no side reactions occur-the label and detection tags react selectively and specifically with one another. This final point is a key advantage of this powerful detection technique; it is possible to apply click chemistry-labeled molecules to complex biological samples and detect them with unprecedented sensitivity due to the extremely low background of the reaction.

    I will be performing a cell proliferation assay using Click-iT EdU kit. At what point can I stop overnight, or do I have to perform all the steps continuously?

    One may store the sample after fixation overnight in PBS at 4oC. For longer storage (<1 week) , store in buffer with 1-2% formaldehyde or in formalin to limit microbial growth. If you use sodium azide as a microbial inhibitor, it must be completely removed prior to the Click-iT reaction.

    A control for a Click-iT EdU labeling experiment uses no EdU and the Click-iT reaction using Alexa Fluor 594 azide. The mouse heart tissue sections are showing non-specific labeling in red, seen in particular clusters of cells. They don't overlap with DAPI. What is the problem?

    The problem is likely not the Alexa Fluor 594 azide. Since there are no alkynes endogenous to mouse tissue, there is nothing for the dye-azide to bind to. Since the background doesn't overlap with nuclei (DAPI signal), this isn't an issue of unintended EdU labeling. This red is autofluorescence from red blood cells; they autofluoresce in the red and don't have nuclei. This can be confirmed by checking a completely unlabeled tissue section (no dye present at all) to see if they are still present and by examining the cells at high magnification and looking for corpuscular shape.

    Can I combine Click-iT or Click-iT Plus reactions with phalloidin conjugates used for actin staining?

    We do not recommend using phalloidin conjugates for staining actin in combination with traditional Click-iT or Click-iT Plus reactions since phalloidin is extremely sensitive to the presence of copper.

    For staining actin in combination with traditional Click-iT or Click-iT Plus reactions, we recommend using anti-α-actin antibodies for staining actin in the cytoskeleton. You can find a list of our actin antibodies here.

    Another option would be to use the Click-iT Plus Alexa Fluor Picolyl Azide Toolkit (Cat. Nos. C10641, C10642, C10643). These Click-iT Plus toolkits provide Copper and Copper protectant separately which makes it easier to titrate the copper concentration to obtain optimal labeling with minimal copper-mediated damage. You may need to optimize the click reaction with the lowest possible concentration of copper and then perform the phalloidin staining.

    How can I generate a positive control for the Click-iT Plus EdU imaging kits?

    Consider the normal replication rate for the cell of interest and culture the cells with multiple doses of EdU for one full cycle. For example, if cells divide every 24 hours, consider 3 or 4 additions of fresh EdU every 6 to 8 hrs and then fix and permeabilize within 2 to 3 hrs after the final addition. This helps to ensure a high level of EdU incorporation in the majority of the population that is replicating. This positive control provides proof that the click reaction and components are working properly.
