MAIN RESEARCH

  • Experimental interactomics of proteins and stable protein complexes
  • Intermolecular interactions in membrane systems involving proteins
  • Biosensor screening of drug prototypes and physiologically active substances: regulators of protein-protein interactions; inhibitors of enzymes and protein oligomerization
  • Technologies of biosensor analysis and diagnostics of socially significant diseases
  • Biosensor technologies: optical biosensors based on the effect of surface plasmon resonance (SPR), development of a methodology for the regeneration of optical chips and new principles of ligand immobilization.
  • Research within the framework of state assignment 122030100168-2 “Development of experimental methods for studying the protein interactome, analysis of protein-protein and protein-ligand interactions, search for regulators of the functioning of target proteins and protein-protein interactions”
  • Proteomic research within the framework of the scientific program of the biological satellite BION-M No. 2.
  • Custom research projects on the topic "Biosensor SPR analysis of the interaction of secondary metabolites of marine fungi with estrogen receptors" (customer - PIBOC FEB RAS under grant RSF No. 25-73-20049, 2025-2027).
  • Carrying out custom scientific researches (as services of “Human Proteome” Core Facilities) for commercial and academic customers (SPR analysis, molecular fishing, analysis of drug immunogenicity, screening of biologically active substances for their interaction with target proteins).
