A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

About

Circular dichroism (CD) allows the measurement of secondary and tertiary structures, the analyse of conformational changes, the kinetic of folding and the thermal and chemical stability of folding.

aviv300

Fluorescence spectroscopy gives access to the analysis of tertiary conformations, of thermal and chemical stability, and of molecular interactions through the measure of fluorescence intensity, anisotropy and life-time.

pti

Infrared spectroscopy (FTIR) allows the measurement of secondary structures of macromolecules, in particular proteins with high ß sheet content.

Access Protocol

PFBMI equipments are available for all scientists worldwide, but a priority is given to members of Institut Pasteur and the Institut Pasteur International Network.
Requests can be submitted at any time  (biophysique@pasteur.fr) attaching a project submission form.

Equipments

Circular Dichroism • JASCO • J-1500/ 450W

The PFBMI has an J-1500/ 450W instrument. Studying macromolecules (and in particular proteins) by circular dichroism allows to obtain information about their folding. For proteins, far UV (180-260 nm) and near UV (250-330 nm) […]

Fluorescence Spectroscopy • Photon Technology International • Quantamaster QM4CW

Fluorescence spectroscopy is a versatile technique which allows to analyze, at steady-state or in real time, the variations of the environment of fluorescent probes, either intrinsic (for instance tryptophans in the case of proteins) […]

Infrared spectroscopy (FTIR) • Jasco • 6100

Fourier Transform Infra Red (FTIR) spectroscopy allows to analyze the secondary structure of macromolecules by measuring absorption frequencies of some specific chemical groups (notably, for proteins, that of the amide bond). Informations given by FTIR are […]
