Immune Monitoring and Flow Cytometry Resource (IMFC)

Director: Channon Smith, Jacqueline Y.


DartLab is a Shared Resource that is used both by basic scientists and by clinicians carrying out mechanistic studies for clinical trials. Services are also available to non-Dartmouth clients. The consolidated Shared Resource moves beyond the simple provisioning of technical services to making complex experiments possible by providing scientific and technological support for implementing advanced, high-complexity assays in a cost-effective way, and by providing a mechanism for the acquisition of new methodologies.

We carry out a spectrum of immunoassays and can develop customized immunoassays to suit your studies. We provide dedicated instruments for your use including cell sorters, flow cytometers, an ELISPOT reader, a Bio-Plex array reader and a Sector Imager, an autoMACS and a Robosep.

    "The Gallios Flow Cytometer is a research system that delivers analytical excellence by coupling extraordinary sensitivity, resolution and dynamic range with high-speed data collection.

    Patented electronics provide accurate and efficient digital signal processing at high event rates over a wide dynamic range of fluorescence intensities. These benefits are packaged in a compact analyzer that delivers stable performance over long periods of time and across a wide range of operating temperatures.

    The Gallios houses up to three highly reliable, solid-state lasers in standard red and blue, with violet available as an option. Easily interchanged optical filters facilitate detection of a variety of dyes and wavelengths.

    An innovative forward-scatter detector provides up to three measurements of cell size and visualization of particles down to 0.404 µm in diameter. A side-scatter detector incorporates an independently focused, high-performance photodiode with electronic attenuation. Six fluorescence detectors provide simultaneous acquisition of up to six fluorescence signals. Up to four fluorescence detectors can be added to the system, enabling concurrent reading of up to 10 colors. Simultaneous measurements of integral, peak and width are available for all parameters, including scatter and fluorescence signals. A selection of up to 62 parameters can be processed per analysis, at acquisition rates of 25,000 events-per-second, with high yield. Three scalable configurations allow for the future addition of more lasers and fluorescence detectors as the applications for complex multi-color flow cytometry expand."
