The National Institute of Biomedical Imaging and Bioengineering has given researchers at the Virginia Polytechnic Institute and State University a $1.3 million grant to create microfluidic tools that can be used to study how proteins and DNA interact within the cells of a single animal at different times. In particular, Chang Lu, an associate professor who will lead the research team, will use his microfluidic chromatin immunoprecipitation, or ChIP, technique, which needs very small amounts of blood or numbers of cells to test disease progression in a single test subject.
