The BrdU Cell Proliferation Assay Package detects 5-bromo-2’-deoxyuridine (BrdU) integrated into mobile DNA throughout cell proliferation utilizing an anti-BrdU antibody. When cells are cultured with labeling medium that incorporates BrdU, this pyrimidine analog is integrated instead of thymidine into the newly synthesized DNA of proliferating cells.
After eradicating labeling medium, cells are fastened and the DNA is denatured with our fixing/denaturing answer. Then a BrdU mouse mAb is added to detect the integrated BrdU (The denaturing of DNA is critical to enhance the accessibility of the integrated BrdU to the detection antibody). Anti-mouse IgG, HRP-linked antibody is then used to acknowledge the certain detection antibody. HRP substrate TMB is added to develop colour. The magnitude of the absorbance for the developed colour is proportional to the amount of BrdU integrated into cells, which is a direct indication of cell proliferation.

Halogenated nucleotides such because the pyrimidine analog bromodeoxyuridine (BrdU) are helpful for labeling nascent DNA in residing cells and tissues. BrdU turns into integrated into replicating DNA instead of thymidine and subsequent immunodetection of BrdU utilizing particular monoclonal antibodies permits labeling of cells in S part of the cell cycle. After pulse-labeling cells or tissues with bromodeoxyuridine, BrdU (Bu20a) Mouse mAb can be utilized to detect BrdU integrated into single stranded DNA.
Key options and particulars
- Sensitivity: 40 cells/effectively
- Pattern kind: Adherent cells, Suspension cells
- Detection technique: Colorimetric

5-bromo-2-deoxyuridine (BrdU) is a pyrimidine analog. It will get integrated into the newly synthesized DNA of proliferating cells instead of thymidine. Biovision’s BrdU Cell Proliferation Assay Package detects integrated BrdU utilizing a mouse anti-BrdU antibody. An anti-mouse HRP-linked secondary antibody is used to detect the anti-BrdU antibody certain to BrdU, which is adopted by addition of TMB (a HRP substrate). The extent of colour improvement is proportional to the amount of BrdU integrated into the cells and can be utilized straight as an indicator of cell proliferation. In comparison with different cell proliferation assays, this package detects solely the proliferating cells and never the seeded cells. This extremely delicate, non-radioactive package detects as much less as 50-100 proliferating cells.
METABOLIC PROLIFERATION ASSAYS
Assays that measure metabolic exercise are appropriate for analyzing proliferation, viability, and cytotoxicity. The discount of tetrazolium salts similar to MTT, XTT, and WST-1 to coloured formazan compounds or the bioreduction of resazurin happens solely in metabolically energetic cells. Actively proliferating cells enhance their metabolic exercise, whereas cells uncovered to toxins may have decreased exercise.
MTT Cell Proliferation Assays
MTT (3-[4,5-dimethylthiazol-2-yl]-2,5- diphenyltetrazolium bromide; thiazolyl blue) is a water soluble tetrazolium salt yielding a yellowish answer when ready in media or salt options missing phenol pink. Dissolved MTT is transformed to an insoluble purple formazan by cleavage of the tetrazolium ring by dehydrogenase enzymes. This water-insoluble formazan will be solubilized utilizing isopropanol or different solvents, and the dissolved materials is measured spectrophotometrically utilizing absorbance as a operate of focus of transformed dye.
XTT Cell Proliferation Assays
In distinction to MTT, the cleavage product of XTT is soluble in water; a solubilization step is subsequently not required. The tetrazolium salt XTT is cleaved to formazan by a fancy mobile mechanism. This bioreduction happens in viable cells solely, and is expounded to NAD(P)H manufacturing via glycolysis. The quantity of formazan dye fashioned straight correlates to the variety of metabolically energetic cells within the tradition.
WST-1 Cell Proliferation Assays
The steady tetrazolium salt WST-1 is cleaved to a soluble formazan by a fancy mobile mechanism that happens primarily on the cell floor. This bioreduction is basically depending on the glycolytic manufacturing of NAD(P)H in viable cells. The quantity of formazan dye fashioned straight correlates to the variety of metabolically energetic cells within the tradition.
