The Click-iT™ EdU Imaging Kit is a trial version of our superior alternative to traditional proliferation assays optimized for fluorescence microscopy applications. In this assay the modified thymidine analogue EdU is efficiently incorporated into newly synthesized DNA and fluorescently labeled with a bright, photostable Alexa Fluor™ dye in a fast, highly-specific click reaction. This fluorescent labeling of proliferating cells is accurate and compatible with antibody methods due to the mild click protocol. This trial-size kit provides sufficient EdU to label up to 6–30 coverslips and enough Alexa Fluor™ 488, 594, and 647 azide to detect new DNA synthesis on 2–10 coverslips with each fluorophore.
• Simple—works the first time, every time, in less time
• Efficient—no denaturation steps or harsh treatment required
• Content-rich results—better preservation of cell morphology, antigen structure, and DNA integrity
• Consistent—not dependent on variable antibody lots for detection

The most accurate proliferation-detection methods are based on the incorporation and measurement of nucleoside analogues in newly synthesized DNA, with bromodeoxyuridine (BrdU) a commonly used analogue. BrdU-labeled DNA is quantitated using anti-BrdU antibodies following DNA denaturation by harsh methods (HCl, heat, or enzymes) to expose the BrdU molecules. This step is time consuming and difficult to perform consistently. The harsh treatment can also adversely effect sample integrity and quality, which makes co-staining with other antibodies challenging.

Superior Proliferation Methodology
The Click-iT™ EdU Imaging Kit provides a superior alternative to BrdU assays for measuring cell proliferation. EdU (5-ethynyl-2'-deoxyuridine) is a nucleoside analog of thymidine and is incorporated into DNA during active DNA synthesis. With Click-iT™ EdU, mild fixation and detergent permeabilization is sufficient for the small molecule-based Click-iT™ EdU detection reagent to gain access to the DNA. As a consequence, the Click-iT™ EdU Imaging Kit is not only easy to use, but more accurate and compatible with cell cycle analysis and other intracellular or extracellular targets for truly content-rich results.

This kit is optimized for fluorescence microscopy applications; visit the Click-iT™ technology area of our website for kits designed for high-content imaging, fluorescence microplate, or flow cytometry platforms.

Notes:
The Click-iT™ assay can be used on cells in culture or in vivo following EdU administration by feeding or injection methods.
The Click-iT™ assay can be used with BrdU in dual pulse experiments by using the anti-BrdU (clone MoBu-1) antibody, which does not cross react with EdU.
The Click-iT™ technology is compatible with immunohistochemical, immunocytochemical, and fluorescent dyes that are fixation tolerant or designed for fixed cell labeling.

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.

Are the Alexa Fluor azides from Click-iT EdU kits available separately?

Yes, but the standalone products are not shipped at the same amount as provided in the Click-iT EdU kits; the amount of dye-azide provided in the Click-iT kits is proprietary information. See these catalog numbers for the standalone products:
- Cat. No. A10266: Alexa Fluor 488 azide
- Cat. No. A10270: Alexa Fluor 594 azide
- Cat. No. A10277: Alexa Fluor 647 azide
