As catalysts and structural elements, proteins are both the drivers and major building blocks of the cell. SRI Biosciences studies proteins using integrated sets of tools in these areas:
High throughput screening for inhibition
Computational and experimental analyses of protein structure
Development of detailed structure-activity relationships
We partner with clients who have needs ranging from simple overproduction of key proteins and protein-based assay development and validation for high throughput applications, to the detailed and complex mechanistic work necessary to describe the behaviors of proteins alone and in combination with small molecules.
- Protein expression and purification at the mg to 100mg scale (focus on pathogens)
- Development of new protein-based/enzymatic assays based on a wide variety of observables: UV/vis, fluorescence, O2 consumption, electrochemistry, HPLC, mass spectrometry
- Development and implementation of immunoassays (e.g., ELISA)
- Refinement and validation of assays for use in high throughput screening
- Determination of mechanism and strength of inhibition of lead compounds against target proteins
- Detailed mechanistic analysis of protein function using spectroscopic, structural, mutagenesis, and kinetics (steady state and transient) tools
- Detailed analyses of proteins and pathways involved in redox and metallobiochemistry
- Development of new bio-analytical methods involving proteins, small molecules and their interactions
