Definitions
- the present invention relates to automated apparatus for performing chemical or biological tests, and in particular immunological tests.
- the first step may consist in depositing on the walls of a solid support an active component, especially in the form of capture antibodies, specific for one or more target antigens of a given pathogen, that one wishes to highlight in a biological sample of a patient.
- the second step then involves contacting the biological sample of the patient with said capture antibodies. If the patient sample contains the target antigen, a complex is formed between the target antigen and the capture antibody. The target antigens attached to the capture antibodies are then contacted with labeled, detection antibodies to reveal the presence of the capture antibody-target antigen-detection antibody sandwich. Such tests are well known to those skilled in the art.
- VIDAS® apparatus As an example of automated apparatus for immunological assays, mention may be made in particular of the VIDAS® apparatus, marketed by the applicant, which is a multiparametric automaton for immunoanalyses. This device is composed of an analytical module that automatically supports all the steps of the analysis until the rendering of results.
- the principle of the VIDAS® test is based on the use of a cone and a reaction bar:
- the cone constitutes the solid phase of the reaction on the wall from which the capture antibodies are fixed. It is for single use and allows sample collection. During the test, it allows the suction / discharge stages intended to successively bring into contact the multiple reagents involved in the test.
- the bar contains all ready-to-use reagents, distributed in the different wells of the bar, and in particular the detection antibodies.
- a well also allows the deposit of the sample that one wishes to analyze.
- the cone sucks and pushes several times the different reagents contained in the wells of the bar until the final reading step.
- the last well of the bar constitutes the reading cell in which the intensity of the reaction is measured in fluorescence.
- This type of device is satisfactory in that it makes it possible to perform an analysis in an efficient manner. It is however desirable to allow an acceleration of the tests to allow to provide analysis results more quickly.
- the subject of the present invention is a chemical and / or biological analysis method comprising the steps of:
- - providing a container defined by a wall comprising an inner surface on which is fixed an active component for allowing a chemical and / or biological reaction with a solution disposed in the container;
- the frequency of the suction / discharge movements is between 0.2 and 20 Hz, preferably between 1 and 15 Hz, and in particular between 2 and 10 Hz.
- the volume sucked and discharged during the succession of suction and discharge movement in the container is between 0.5 and 360 ⁇ _, preferably between 1 and 50 ⁇ _.
- the present invention also relates to a device for carrying out a method as described above, comprising:
- the suction / discharge means being arranged to carry out suction / discharge movements in the container at a frequency adapted to cause a resonance of the liquid so as to deform the free surface thereof and to generate a distribution preferential fluid along inner surface of the container wall.
- the container has a conical shape.
- the device further comprises a well intended to receive a liquid solution, and relative displacement means of said well relative to the container, the displacement means being arranged to move the container between a first position called low in wherein an orifice of the container is in contact with the liquid solution so as to allow aspiration of said solution from the well into the container, and a second so-called high position, in which the orifice of the container is disposed above the free surface of the liquid solution present in the well, in which position the succession of suction / discharge movement is applied to the solution present in the container.
- Figure 1 is a schematic representation of a device according to the invention.
- FIG. 2 diagrammatically shows the distribution of a liquid during suction / discharge operations in a container of the device of FIG. 1 during the application of a method according to the invention.
- a device comprises a cone-shaped container 2 defined by a wall 3 which has an opening 4 at its tip to allow the suction or discharge of liquid .
- the upper part of the cone is connected by fluidic communication means 5 to suction / discharge means 6 of a liquid in the cone 2.
- the inner surface 7 of the wall of the cone comprises a deposit 8 of an active component intended to allow a chemical and / or biological reaction with a solution 9 placed in the cone 2.
- the device also comprises means 10 for receiving a reaction strip 12 containing ready-to-use reagents, distributed in the various wells 13 of the strip.
- the reagents may consist in particular of detection antibodies.
- one of the wells 13 may also allow the deposit of the sample that it is desired to analyze.
- the device further comprises means 14 for supporting and relative movement of the cone relative to the reaction bar containing the wells.
- the displacement means are arranged to allow movement along the axis of the bar as indicated by the arrow A to position the tip of the cone 3 facing a particular well, and a movement perpendicular to the axis of the bar indicated by the arrow B, to allow the end 4 of the cone 2 to enter the well 13 to take a solution present in the well or to discharge the contents of the cone 2 in said well.
- suction / discharge means 6 it is known to use the suction / discharge means 6 to allow suction and discharge of liquid between a well 13 and the cone 2 or reaction vessel.
- the cone 2 is moved opposite a well 13, then the end 4 of the cone 2 is introduced into the well until it penetrates into a solution contained in the well 13. An aspiration of a determined quantity of solution is carried out, thanks to the suction means 6.
- the cone is then moved by the displacement means 14 to reach a high position or mixing position in which the end of the cone 2 is above the free surface of the solution present in the well 13.
- the end of the cone 2 is placed above the solution surface present in the well, but remaining in the well enclosure.
- the suction means 6 are arranged to generate suction / discharge movements in the cone 2 at a frequency adapted to cause a resonance of the liquid 9 so as to deform the free surface thereof and to generate a distribution of the fluid along the inner surface 7 of the wall of the cone 2.
- the preferential distribution of the liquid in the cone is then carried out as shown in FIG. 2, a greater quantity of liquid being present on the wall of the container relative to the quantity disposed at the center of the container.
- the frequency f of the suction / discharge movements making it possible to obtain the phenomenon of resonance and preferential distribution of the liquid along the walls of the cone is between 0.2 and 20 Hz, preferably between 1 and 15 Hz, and preferred way between 2 and 10 Hz.
- the amount of volume v sucked and discharged into the container is between 0.5 and 360 ⁇ .
- a volume amplitude v suction / discharge movements of the order of 5 ⁇ can be advantageously used, and a discharge frequency of between 4, 3 and 4.5 Hz.
