Cell deposition system

Abstract

A system for depositing cells on an analysis plate, the cells being contained in a cell suspension including a fixing agent and the cells, included, for receiving the suspension, a chamber ( 5 ) which is positioned above the analysis plate and whose base is open and extends opposite a cell depositing zone of the plate and a material for absorbing the fixing agent placed around the chamber and the depositing zone of the plate. The chamber is mounted so as to be able to be moved between a first position in abutment against the analysis plate in order to allow the cells to be deposited on the depositing zone of the plate via decantation and a second position remote from this analysis plate in order to place the chamber in a fluid relationship with the absorption material in order to allow this material to absorb the fixing agent.

1 . System for depositing cells on an analysis plate ( 1 ), the cells being contained in a cell suspension ( 4 ) comprising a fixing agent and the cells, comprising, for receiving the suspension, a chamber ( 5 ) which is positioned above the analysis plate ( 1 ) and whose base is open and extends opposite a cell depositing zone of the plate and a material ( 7 ) for absorbing the fixing agent placed around the chamber and the depositing zone of the plate, characterised in that the chamber ( 5 ) is mounted so as to be able to be moved between a first position ( FIG. 1 ) in abutment against the analysis plate ( 1 ) in order to allow the cells to be deposited on the depositing zone of the plate ( 1 ) by means of decantation and a second position ( FIG. 2 ) remote from this analysis plate ( 1 ) in order to place the chamber ( 5 ) in a fluid relationship with the absorption material ( 7 ) in order to allow this material to absorb the fixing agent. 
   
   
       2 . System according to  claim 1 , characterised in that the base of the chamber ( 5 ) is provided with sealing means ( 9 ). 
   
   
       3 . System according to  claim 1 , characterised in that the chamber ( 5 ) is connected to means ( 10 ) for moving the chamber between its two positions at the end of a predetermined period of time. 
   
   
       4 . System according to  claim 3 , characterised in that the predetermined period of time is approximately 30 minutes. 
   
   
       5 . System according to  claim 1 , characterised in that the absorption material ( 7 ) is in the form of a sheet of absorbent paper which is placed around the depositing zone of the plate and the chamber ( 5 ). 
   
   
       6 . System according to  claim 2  characterised in that the chamber ( 5 ) is connected to means ( 10 ) for moving the chamber between its two positions at the end of a predetermined period of time. 
   
   
       7 . System according to  claim 6 , characterised in that the predetermined period of time is approximately 30 minutes. 
   
   
       8 . System according to  claim 2 , characterised in that the absorption material ( 7 ) is in the form of a sheet of absorbent paper which is placed around the depositing zone of the plate and the chamber ( 5 ). 
   
   
       9 . System according to  claim 3 , characterised in that the absorption material ( 7 ) is in the form of a sheet of absorbent paper which is placed around the depositing zone of the plate and the chamber ( 5 ). 
   
   
       10 . System according to  claim 4 , characterised in that the absorption material ( 7 ) is in the form of a sheet of absorbent paper which is placed around the depositing zone of the plate and the chamber ( 5 ).
