Product Information
Product introduction:
This product BrdU detection kit is used for cell proliferation detection of cells and tissue sections. BrdU (5-Bromo-2-deoxyUridine), which is 5-bromodeoxyuridine, is an analog of thymidine (T). The principle of this kit is that BrdU can replace thymidine T by competition. Enter the DNA synthesis phase (S phase). When BrdU is incorporated into cells in vigorous division, the cells containing BrdU can be detected by using anti-BrdU antibody and antibody ligase or fluorescein as an indicator system, and combined with other cell markers for dual labeling, the proliferation of cells can be judged Types, proliferation speed, etc. are of great significance to the study of cell dynamics. BrdU enters tissue cells through intravital injection or cell culture, and the DNA incorporated into it is accurately positioned, which can effectively reflect the level of newly synthesized DNA in S-phase cells, and is less affected by the internal and external environment of the cell, and the label will not be lost.

Notes:
1. For cell slide samples, the concentration and processing time of BrdU are related to the cell types. Generally speaking, the concentration and time required to treat tumor cells are low. Cells with slow proliferation such as fibroblasts or epithelial cells need to increase the concentration and prolong the action time. The recommended concentration range is 20-100 μM and the action time is 40 min. -4 hours, can be adjusted according to the specific cell types.
