The Protein-Protein Interactions Analysis Platform, located across multiple rooms in the Bellini Life Sciences Complex, provides state-of-the-art instrumentation for studying biomolecular interactions. Whether performing preliminary affinity characterization or in-depth thermodynamic analysis, this facility enables researchers to quantify binding interactions, protein stability, and molecular structure.

Key Equipment & Capabilities:

• Isothermal Titration Calorimeters (ITC) (x3) – Measures binding enthalpy, entropy, and affinity in protein-protein, protein-ligand, and nucleic acid interactions.
• Surface Plasmon Resonance (OpenSPR) – Provides real-time, label-free binding affinity measurements, critical for kinetic and affinity characterization of biomolecular interactions.
• Multi-Angle & Dynamic Light Scattering (MALS/DLS) – Determines molecular size, aggregation state, and conformational stability of proteins and macromolecular complexes.
• Analytical Ultracentrifuges – Used for molecular weight determination and hydrodynamic analysis of proteins in solution.
• Circular Dichroism (CD) Spectrometer – Analyzes protein secondary structure and folding properties, essential for structural biology and stability studies.
• Biocomp Gradient Station – Supports protein purification, crosslinking experiments, and density gradient fractionation for biomolecular characterization.
• Fluorometers – Quantifies binding affinities and protein stability, providing fluorescence-based assessments of biomolecular interactions.

This facility is crucial for structural biology, drug discovery, and biophysical studies, enabling researchers to characterize macromolecular interactions with high precision.
