Development of GC systems for industrial analysis and laboratory analysis
The main targets of this topic are related to size and analysis time reduction in order to carry out gas analysis according to industry requirements. New original tools are designed based on monolithic capillary columns, with operating pressure as high as 60 bar. Such integrated device operate in non-conventional GC conditions (very short column, high pressure, high gradient rate, fast detector).

Preliminary results obtained with capillaries designed in TechSep team (see figure) have already demonstrated the ability to separate industrial mixtures in short time (less than 15 s) taking into account the instrumental constraints. The fundamental part of the research project aims to understand separation processes with high pressure of carrier gas which lead to original selectivity control and high efficiency. Several monolithic columns with controlled surface properties are designed, hyphenated with specific injectors and detectors, and used to solve analytical problems encountered by the industrial partners of the project.

 

 

Project nano-WAC
The project nano-WAC aims to develop a new miniaturized affinity chromatography-based technology (nano-WAC) that will enable the innovative ligand-screening against native membrane proteins (MPs), notably G protein–coupled receptors (GPCRs). Our strategy, based on the combination of the separation/detection powers of affinity chromatography and mass spectrometry (nano-WAC-MS), will open the way to the screening of fragment library for the identification of weak affinity fragments in the context of the Fragment Based Drug Discovery approach

Partners :

  • Jean-louis Baneres (Cell Pharmacology group, Institut des Biomolécules Max Mousseron (UMR 5247), at Montpellier. This group holds a world-class expertise in the production of functional purified GPCRs, including GHSR
  • Renaud Wagner, heading a technological platform, IMPReSs (Integral Membrane Proteins Research and Services), is an expert of the bio-production, purification and characterization developments of GPCRs.
  • I Krimm Fragmentech team  (new labs) has a strong expertise in the characterization of protein-ligand complexes and fragment-based screening by NMR, with a 1000 fragment library developed at ISA

 

Project AffinHit – 2020
Funded by ICL
The project aims to assess the potential of miniaturized low affinity chromatography for the separation of glycoclusters from combinatorial libraries and quantification of their affinity for immobilized lectins.

Partners: Laurent Vial /Julien Leclaire (Equipe Chimie Supramoléculaire Appliquée, ICBMS – UMR5246).
