Joseph Gall (Carnegie Institution): In Situ Hybridization

www.ibiology.org/genetics-and-gene-regulation/in-s…

Talk Overview:
In in situ hybridization, RNA or DNA molecules can be visualized in an immobilized cell, tissue, or tissue section. This technique, which was pioneered by Joe Gall in 1968, works by hybridizing a labeled RNA or DNA molecule that is complementary to the RNA or DNA of interest. In his talk, Gall describes the experiments that inspired him to develop this technique, and the key experiments that led to the first visualization of RNA and DNA inside the cell.

Speaker Biography:
Joe Gall is a Professor at the Carnegie Institution for Science and is considered one of the founders of the field of cell biology. He has spent much of his career studying the nucleus and its contents, and has made numerous significant contributions to our understanding of chromosome structure and function. Gall, a distinguished microscopist, is one of the first members and an early president of the American Society for Cell Biology. Gall, who is a member of the National Academy of Sciences, has received numerous awards for his contributions to science, including the Louisa Horwitz Prize and an Albert Lasker Special Achievement Award.
