Imaging cell facility

The cellular imaging facility of the CPTP offers a wide array of biophotonic approaches, allowing to visualize biological events from the nanometric to the organ scale.

Microscopes are available for scientists from the CPTP but also from outside the institute (public or private domain).

Thanks to the connection of the facility with TRI (Toulouse Réseau Imagerie), the facility is ISO9001 V2015 and NFX 50-900 v2016 certified, in order to ensure a continuous improvement and customer satisfaction.

Services provided

For every new user, we organize a first meeting to help to choose the best protocol and to decide which microscope to use.

The facility offers two types of services:

  • Training: A training provided by the engineers of the facility is mandatory to be granted an access to the microscopes and to book them
  • Expertise: Engineers of the facility can help you for the technical development of your projects and for the analysis of your data.

Three computers are available for image treatment and analysis. You can also use them to perform deconvolution on wide field images. On request, engineers of the facility can also write macros for ImageJ in order to automate your analyses.

Three softwares are available:

  • Metamorph (Universal Imaging)
  • ImageJ: free software mainly for 2D or 2D+ time image analysis. Macros can be written to automate analyses.
  • Imaris: for 3D and 3D+time analysis. Can create surfaces, track cells and generate statistical analyses. Movies can also be created with Imaris.
