How is BrdU Incorporated?

BrdU (5-bromo-2-deoxyuridine) is a thymidine analogue which is incorporated into the cells of DNA synthetic phase. Replicating cells undergo DNA synthesis in a highly regulated, S-phase of the cell cycle. Furthermore, loss of control of cell proliferation underlies the pathology of diseases like cancer.

How do you do a BrdU assay?

Two commonly used methods are intraperitoneal injection and oral administration. Dilute BrdU in PBS to make a sterile solution of 10 mg/mL….Oral administration

Dilute BrdU to 0.8 mg/mL in drinking water.
After treatment with BrdU, the animals can then be sacrificed according to standard protocols.

How is bromodeoxyuridine BrdU incorporated in cells?

During S phase of the cell cycle (when DNA replication occurs), BrdU can be incorporated in place of thymidine in newly synthesized DNA molecules of dividing cells. Bromodeoxyuridine releases gene silencing caused by DNA methylation.

Why is BrdU used?

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. As a thymidine analog, it is a marker of DNA synthesis.

What is the process of proliferation?

Definition. Cell proliferation is the process that results in an increase of the number of cells, and is defined by the balance between cell divisions and cell loss through cell death or differentiation. Cell proliferation is increased in tumours.

How does BrdU cause mutation?

During S phase of the cell cycle (when DNA replication occurs), BrdU can be incorporated in place of thymidine in newly synthesized DNA molecules of dividing cells. Because BrdU can replace thymidine during DNA replication, it can cause mutations, and its use is therefore potentially a health hazard.

What does Proliferation mean in politics?

Proliferation describes growth by the rapid multiplication of parts. In its politico-military context, proliferation most commonly refers to nuclear weapons, and sometimes covers all weapons of mass destruction—biological, chemical, and radiological as well as nuclear.

How is the BrdU labeling and detection protocol used?

BrdU Labeling and Detection Protocol DNA synthesis–based cell proliferation assay Cell proliferation can be measured with the thymidine analog BrdU (5-bromo-2’-deoxyuridine) following its incorporation into newly synthesized DNA and its subsequent detection with an anti-BrdU antibody. This protocol can be used for:

How is BrdU staining and BrdU assay performed?

Print this protocol. BrdU labeling can be performed in vitro for cell lines and primary cell cultures, or in vivo for labeling cells within a living animal. During the BrdU assay, BrdU is incorporated into replicating DNA and can be detected using anti-BrdU antibodies.

How long is the incubation period for BrdU?

Note: BrdU incubation time depends on how rapidly the cells divide. Primary cells may need up to 24 hours, while rapidly proliferating cell lines may only need one hour. The exact time required to achieve the optimal signal-to-noise ratio should be optimized.

How is BrdU used to detect stem cell proliferation?

Here, we describe a protocol for BrdU incorporation analysis in hematopoietic stem and progenitor cells that can provide a sensitive measure of cell division even in rare cell populations. In combination with flow cytometry, this method can be generalized to analyze other cell populations and other tissues as identified by cell surface markers.
