The Center for Macromolecular Interactions
The Center for Macromolecular Interactions (CMI) is primarily a shared instrument facility offering training and access on our technologies. The CMI has a mission to enhance basic research in the HMS community by providing scientific consultation, training and access to shared biophysical instruments for the characterization and analysis of macromolecules and their complexes.
Molecular Properties
The CMI offers training and access to instruments to measure molecular properties, including Differential Scanning Fluorimetry (DSF), Circular Dichroism (CD), Light Scattering, including size-exclusion chromatography with multi-angle light scattering (SEC-MALS), Dynamic Light Scattering (DLS), Mass Photometry (MP), and protein production, including Fast Protein Liquid Chromatography (FPLC) and Cell-free Protein Synthesis. The CMI also offers limited data collection services on select CMI technologies, as staff and instrument time allows.
Molecular Interactions
The CMI also offers training and access to instruments to measure molecular interactions, including Isothermal Titration Calorimetry (ITC), Surface Plasmon Resonance (SPR), Biolayer Interferometry (BLI), MicroScale Thermophoresis (MST), and a Multimode Plate Reader for Fluorescent and Luminescent assays.
