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  give access to the analysis of tertiary conformation, of thermal and chemical stability and of molecular interactions through the measure of fluorescence intensity, anisotropy and life-time.

 Infrared spectroscopy (FTIR) allows the measurement of secondary structures of macromolecules, specially proteins with high content in  ß sheath

Access Protocol

Equipments on the PFBMI are available for the entire scientific community, national and international, but a priority is given at Institut Pasteur and Institut Pasteur International Network.
The PFBMI is performing the analysis as one goes along their reception (biophysique@pasteur.fr). An inital form (upload here) must be joined

Circular Dichroism • AVIV • 215

The PFBMI has an Aviv 215 instrument with accessories for the measurement of total fluorescence and to perform titrations. Studying macromolecules (and in particular proteins) by circular dichroism allows to obtain information about their […]

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 […]
