How does EdU labeling work?
The EdU method is as effective as BrdU without requiring harsh denaturation or secondary antibodies to identify proliferating cells. Thus, the non-antibody EdU system allows more flexibility by enabling co-labeling with multiple antibodies to other cellular proteins involved in regeneration.
Is EdU a fluorescent?
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.
What is EdU staining for?
Product overview. EdU Assay / EdU Staining Proliferation Kit (iFluor 488) ab219801 provides a sensitive and robust method to detect and quantify cell proliferation in live mammalian cells using flow cytometry or fluorescence microscopy.
What is cell proliferation assay?
Cell proliferation assays are designed to quantify the relative rates of cell division within such target tissues using specialized immunohistochemical staining techniques to detect proliferating cells.
How is EdU detected?
Detection of EdU employs the copper(I) catalyzed click reaction with an azide modified fluorescent dye to form a stable triazole ring. Because of the small size of the click detection reagent, no harsh denaturation steps are needed to gain access to the DNA.
What is the difference between EdU and BrdU?
EdU assay. Unlike assays using BrdU staining, Click-iT EdU assays are not antibody-based and therefore do not require DNA denaturation for detection of the incorporated nucleoside.
Is EdU toxic?
A drawback of the use of prolonged EdU treatments to assess cell cycle parameters came from studies in mammalian cell lines revealing that EdU is a toxic compound that can provoke DNA damage, activate cell cycle checkpoints that impair cell cycle progression and trigger apoptosis (Zhao et al., 2013).
What are EdU positive cells?
5-Ethynyl-2′-deoxyuridine (EdU) is a thymidine analogue which is incorporated into the DNA of dividing cells. EdU is used to assay DNA synthesis in cell culture and detect cells in embryonic, neonatal and adult animals which have undergone DNA synthesis.

How do I check cell proliferation?
DNA synthesis assays are the most accurate and reliable way to detect cell proliferation in the laboratory. Traditionally, radiolabeled 3H-thymine is incubated with cells for several hours or overnight.
How do you test for proliferation?
The most reliable and accurate method of assessing cell proliferation is a measurement of DNA-synthesizing cells. This relies on incubating live cells with compounds capable of being incorporated into newly synthesized DNA. These compounds can then be detected with a reporter.
How do you dissolve EdU?
1. Prepare a 10 mg/mL solution of EdU by adding PBS to EdU powder and mixing well in a water bath (55°C-65°C) until the EdU is fully dissolved. Although the manufacturer recommends dissolving EdU powder in dimethylsulfoxide (DMSO), in our experience most of the tadpoles died after injection of EdU dissolved in DMSO.
What is BrdU used for?
Bromodeoxyuridine (BrdU) is a thymidine analog that incorporates DNA of dividing cells during the S-phase of the cell cycle. As such, BrdU is used for birth dating and monitoring cell proliferation.
How does a BrdU assay work?
Bromodeoxyuridine (BrdU) incorporation assays have long been used to detect DNA synthesis in vivo and in vitro. The key principle of this method is that BrdU incorporated as a thymidine analog into nuclear DNA represents a label that can be tracked using antibody probes.
Which pesticide is most toxic to humans?
Paraquat is highly toxic to humans; one small accidental sip can be fatal and there is no antidote. The product labels clearly prohibit pouring paraquat into food or beverage containers with the prominently-placed statements: “NEVER PUT INTO FOOD, DRINK OR OTHER CONTAINERS” and.
Is EdU toxic to cells?
2′-deoxy-5-ethynyluridine (EdU) has been previously shown to be a cell poison whose toxicity depends on the particular cell line.
How do you test cell growth?
What is needed for cell proliferation?
To produce two viable daughter cells at mitosis, a proliferating cell must replicate all of its cellular contents. This imposes a large requirement for nucleotides, amino acids, and lipids. During growth, glucose is used to generate biomass as well as produce ATP.
Can I dilute DMSO with water?
Yes, you can dilute the solution of your compound in DMSO with distilled water. However it depends on the solubility of your compound in water and the degree of the dilution. In many cases your compound can precipitate from the resulted mixter and you get the suspension.
What is a solvent Year 5?
A solvent is the substance that does the dissolving – it dissolves the solute. In salt solution, water is the solvent.
What is BrdU a marker for?
Which pesticide leads to death?
HHPs of World Health Organization (WHO) toxicity classes Ia, Ib and II – such as the organophosphorus insecticides monocrotophos, phorate, and methyl parathion or the herbicide paraquat [19] – have been responsible for most pesticide suicides worldwide over the last five decades [20, 21].
How do you test your body for pesticides?
Urine and blood tests may be able to detect pesticide residues or metabolites to confirm acute exposures.
How do you know if you have too many toxins in your body?
Symptoms of toxicity can be varied and may include: poor circulation, swelling, headaches, migraines, stress, anxiety, depression, allergies, poor skin, yeast, arthritis, fatigue, constipation, obesity, cellulite, sinus issues, gout, digestive disorders, cold/respiratory disorders, insomnia, bloating, and gas.
What is a good cell viability?
A good cell viability is anywhere between 80-90% in most of the cell lines.
What is cell growth rate?
The growth rate is the change in the number of cells per minute, which we estimate as the change in OD per minute. But the instantaneous change is a function of the number of cells that are present at any given moment: (1)
