Researchers Develop Improved Method to Visualize Biologic Molecules

PLoS Press Release for our first paper on mRNA quantification in whole embryos.

“How are biologic molecules arranged inside the embryo so that embryonic development occurs reliably every time? Princeton researchers, led by Thomas Gregor, an assistant professor of physics and the Lewis-Sigler Institute for Integrative Genomics, and Shawn Little, a postdoctoral fellow in the laboratory of Professor Eric Wieschaus in the Department of Molecular Biology, have developed a new method to better understand how an embryo’s basic molecular makeup helps ensure that the embryo’s development occurs reliably every time. The results of this research into the fruit fly Drosophila introduce a method for making precise measurements of biologic units (so-called mRNA molecules) that play a key role in development. The findings are published in the March 1st issue of  in the online, open access journal PLoS Biology.”
