BrdU Antibody

Bromodeoxyuridine (BrdU) chemical structure representation.

Immunofluorescence microscopy images of paraformaldehyde-fixed, paraffin-embedded pancreas sections stained with antibodies against BrdU (red or pink) and counterstained with DAPI (blue) and imaged with a 40× objective. DAPI stained nuclei (blue) indicate non-dividing cells, immunostained red and pink nuclei indicate actively dividing pancreatic ß-cells. The antibodies were diluted to 2.7 µg/ml. and incubated with tissue sections overnight at 4 degrees. Donkey anti-rabbit secondary antibody was diluted 1:2500.

Immunofluorescence Microscopy of Rabbit anti-BrdU antibody. Tissue: 293T cells transfected expressing GFP-MCM9 L. Fixation: 0.5% PFA. Antigen retrieval: not required. Primary antibody: BrdU antibody at 10 µg/ml for 1 h at RT. Secondary antibody: Anti-rabbit ATTO550 secondary antibody at 1:10000 for 45 min at RT. Localization: BrdU is nuclear. Staining: BrdU in merged image shows with green and purple fluorescent signal with DAPI nuclear counterstain.

SOX2 represses proliferation in the developing spinal cord and stomach.(A) Percentage of cells expressing high or low levels of SOX2 labelled by a one hour pulse of BrdU in the E11.5 mouse spinal cord. Dotted lines in insets surround area of greatest BrdU incorporation. (B) Average background normalized SOX2 expression level and percentage of cells labelled by a one hour pulse of BrdU in the E11.5, E13.5 and E15.5 anterior and posterior stomach. (C) Percentage of electroporated cells in the chick spinal cord labelled by a 30 minute pulse of BrdU following misexpression of GFP, SOX2 or dnSOXB1. (D) Percentage of electroporated cells in E13.5 stomach explants labelled by a 30 minute pulse of BrdU following overexpression of GFP, SOX2 or dnSOXB1. All error bars represent standard deviations between experiments and p-values are calculated with two sided, unpaired t-tests (* = P < 0.05, ** = P < 0.01, *** = P < 0.001).
