Several data processing stations with the following software :
FlowJo, Diva, Kaluza, SpectroFlow.
1 clean room in L2 containment for cell sorting.
It is requested, for each
publication that required the use of the device, that the
department be listed in the acknowledgements.
Objective
:
The initial objective was to open
a high-performance flow cytometry center, able to provide
multiparametric analysis and sorting. Integrated in the IRMB and
being part of MRI, the laboratory participates in the work of
regional laboratories. This laboratory, which does not have its
own theme, is widely open to the regional scientific community:
INSERM, CNRS, University of Sciences, Faculty of Pharmacy,
IFREMER, IRD, CIRAD, INRA, ENSAM... In recent years, the technical
evolution of the equipment has led many laboratories to analyze
and purify cells by means of flow cytometry to better clarify
their role or analyze their content (protein, DNA, RNA... ),
whether human, animal, plant, bacterial, marine... The needs of
laboratories are increasing with the evolution of technologies,
many studies require the use of analyzers and high performance
sorters.
Activity :
The flow cytometry service is a structure that operates as a common
service.
What distinguishes FMC from other preparative techniques is that it
offers the possibility to work simultaneously on several parameters.
No other method, whether physico-chemical (gradient centrifugation,
elutriation) or immunological (panning, columns, rosettes) offers
this versatility. It is thus possible to analyze and sort
populations on a multiparametric basis: two morphologies and up to
40 fluorescences on the latest generation of commercial instruments.
For the time being, the following topics (using flow cytometry
analysis) are being addressed in response to the requests expressed:
+The study of the proliferation of various cell types (lineages,
lymphocytes...) by DNA labelling.
+analysis of cell populations labelled with monoclonal antibodies
(multiple labelling).
+ Quantification of membrane proteins by using calibrated standards
(QIFIKIT).
+ study of apoptosis.
+study of protein expression according to the cell cycle.
+study of the DNA content of plants (lemon, coffee, rice,
petunia...) by means of the dyes used for the marking of the DNA
previously mentioned.
+Cellular sorting using the analysis techniques mentioned above.
