Since the two chemicals are analogous, some spots of the genetic code that call for Thymidine will instead receive Brd U.

The special thing about Brd U is that it can be stained with an antibody using immunohistochemical methods, whereas Tritiated Thymidine is only detected by radiographic techniques.

Specifically, we explain how to inject into animals exogenous markers of proliferation (i.e., Brd U) and prepare brain tissues to perform immunofluorescence reactions for neuronal markers in combination with Brd U staining.

As Brd U is incorporated in the DNA during the S-phase of the cell cycle of proliferating cells and is then inherited by daughter cells, by coupling Brd U-immunoreactivity together with the immunolabeling for neuronal markers, we provide the general procedures that can be applied to identify adult-born neurons and to characterize their specific phenotypes in different brain regions, under physiological condition or in pathological states.

In order to determine whether the brain is undergoing neurogenesis, scientists needed to devise a way to mark proliferating cells.

Furthermore, human ES cell and i PS cell differentiation to cerebral cortex recapitulated in vivo development to generate all classes of cortical projection neurons in a fixed temporal order.

Binding of the antibody requires denaturation of the DNA, usually by exposing the cells to acid or heat. The Br substitution can be used in X-ray diffraction experiments in crystals containing either DNA or RNA.

The Br atom acts as an anomalous scatterer and its larger size will affect the crystal's X-ray diffraction enough to detect isomorphous differences as well. A carbon substrate added to incubations of environmental samples will cause the growth of microorganisms that can utilize that substrate.

Brd U is a synthetic analogue of Thymidine that is also incorportated into cells during DNA replication, which allows us to successfully identify dividing cells.

Essentially, Brd U provides scientists with a way of staining cells that are proliferating in the human brain. When cells are synthesizing new copies of genetic material during S phase, they pull nucleotides from the intracellular environment to create a strand of DNA.
