Plant Electrophysiology Platform (PEP)
IPSiM hosts a plant electrophysiology and heterologous expression platform (PEP-IPSiM) unique in France. The platform brings together 8 recording stations dedicated to specific applications for electrophysiological analyzes (characterization of the activity of transport proteins, mainly by voltage-clamp or patch-clamp on isolated cells) and/or for the heterologous expression of proteins plant membranes in cellular expression systems (Xenopus oocytes, animal cells in culture, plant protoplasts).
It is placed under the scientific responsibility of Alexis De Angeli (DR CNRS) and Benoît Lacombe (DR CNRS) and two engineers are in charge of the PEP platform: Claire Corratgé-Faillie (IR CNRS, technical manager) and Elsa Demes- Causse (IE CNRS).
The platform also serves as a support for theoretical and practical training within the framework of thematic schools (thematic school “SIGNALING, DYNAMICS AND MEMBRANE TRANSPORT” – University of Montpellier and biannual international school “MISTRAL”) and trains young researchers each year to electrophysiology.
Please always mention the advice and technical support provided by the platform staff by adding the following sentence in the “Acknowledgments” section of the acknowledgments:
“We acknowledge the Plant Electrophysiology Platform (PEP) from the Institute for Plant Sciences of Montpellier (IPSiM) for technical support and assistance. »
PEP personnel directly involved in experiments forming part of a manuscript should be added to the list of co-authors.
Access modalities
An email address allows you to directly contact all staff assigned to PEP (umr-ipsim-pep@supagro.fr)
The user chart, the main operating methods used on the PEP platform, the equipment instruction sheets as well as the list of the main ones available are recorded and accessible below in the Documents tab. The management and maintenance of equipment is financed from a specific line in the UMR IPSiM budget. The platform agenda (reservation of recording stations) is accessible via an online application on the IPSiM Intranet (For external scientists, please contact the managers).
A committee of platform users is brought together annually by the scientific managers.
