How does BrdU stain work?
Bromodeoxyuridine (BrdU) is a thymidine analog that incorporates DNA of dividing cells during the S-phase of the cell cycle. Once incorporated, these nucleoside analogs serve as cell cycle and proliferation markers that can be detected using labeled probes to identify cells that are actively proliferating.
What is BrdU assay used for?
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.
Is cell growth and proliferation the same?
Cell growth refers to the increase in cell size (mass accumulation) while cell division describes the division of a mother cell into two daughter cells (1->2->4->8, etc.). Cell proliferation is the process of generating an increased number of cells through cell division.
What is BrdU labeling and detection protocol?
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 do you label cells with BrdU?
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.
What does BrdU stand for?
BrdU (Bromodeoxyuridine / 5-bromo-2′-deoxyuridine) is an analog of the nucleoside thymidine used in the BrdU assay to identify proliferating cells. 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.
How do you remove BrdU from cells?
Remove the BrdU labeling solution from the cells and wash twice in PBS for about 5 seconds per wash. Wash three more times with PBS for two minutes each. Fix and permeabilize cells according to standard immunocytochemistry (ICC) protocols.
