Proteomics is a powerful, rapidly advancing field that enables the analysis (involves the identification of protein structure and function) of a total set of proteins within cells or tissues. Since proteins are the functional units within cells, it helps in elucidation of pathological and drug developments at the molecular level. Genomics and metabolomics are the appurtenant pump that are to be routinely applied throughout the drug-development process as well as after a product enters the market.

However, despite its enormous potential, proteomics technologies have not been moved yet from the bench scale into the clinics. One of the main reasons behind this reality is the laborious series of delicate, high cost equipment and complex steps in the analysis workflow, which are still waiting to being reduced into the routine practice. These critical steps include:

  • Protein identification and differential proteomics (LTQ Orbitrap)
  • Mass determination (LC/MSD time-of-flight)
  • Peptide synthesis (Apex 396, CEM Liberty)
  • Protein purification (ÄKTAexplorer-100 FPLC)
  • Electrophoresis (Bio-Rad GS-800 densitometer, Bio-Rad Molecular Imager FX,Protein Simple Fluor-Chem M, Bio-Rad PD Quest software for 2-D gel analysis)
  • Nano-fluidic immunoassay (Protein Simple CB1000), sophisticated sample preparation and pre-fractionation, on-line separation, multi-analyte outputs as well as data mining.

In India, the bottlenecks in the proteomic assay in clinics can be overcome plausibly by implementing PPP (Public-Private-Partnership) model based health sector by developing and testing on-line high-throughput technology for rapid qualitative and quantitative characterization of proteins in a biological sample. These activities must be divided into technology-oriented improvements in the currently used approaches and developments of new analytical methods and/or protocols.

Toward a goal of improving patient care, the facility must conducts research in the areas of mass spectrometry-based differential proteomics, peptide synthesis, protein and peptide purification, and protein identification, characterization and expression.
