Hello, we are interested in labelling nuclear DNA with EdU, which is suppose to be a better substitute of BrdU.

We are dealing with a cell line which grows very slowly with the doubling in time of few days (3-5 days). Therefore, we are a bit concerned about possible toxicity issues after exposing the cells for a long time with EdU.

Besides, it seems that the gold standard EdU kit (Thermofisher) is very expensive (nearly 800 euros for 25 ml of cell culture medium). Is anybody aware of alternative kits/companies where we could buy it from, which are less expensive but with still compatible result quality?

Thank you
