Brain Science = Biology + Engineering, Jennifer Welborn, Guangyu Xu, Morton Sternheim, Chris Emery
Science and Engineering Saturday Seminars
This interdisciplinary (physical and life sciences) seminar exposes participants to cutting edge research at UMASS, Amherst, on cell imaging using a chip which gathers a variety of data on the activities of single cells. Part of the seminar will be a presentation of current research in this area, followed by hands-on activities and a visit to the lab where this research is conducted. Application of this new technology to brain research will be discussed as well as the NGSS standards alignment and classroom applications at various levels and disciplines.

Adaptor protein Grb2 binds phosphotyrosines in the epidermal growth factor (EGF) receptor (EGFR) and thereby links receptor activation to intracellular signaling cascades. Here, we investigated how recruitment of Grb2 to EGFR is affected by the spatial organization and quaternary state of activated EGFR. We used the techniques of image correlation spectroscopy (ICS) and lifetime-detected Förster resonance energy transfer (also known as FLIM-based FRET or FLIM-FRET) to measure ligand-induced receptor clustering and Grb2 binding to activated EGFR in BaF/3 cells. BaF/3 cells were stably transfected with fluorescently labeled forms of Grb2 (Grb2-mRFP) and EGFR (EGFR-eGFP). Following stimulation of the cells with …
