Definitions
- the invention relates to a method for carrying out an electrochemical measurement on a liquid measurement sample in a measuring chamber accessible via lines, wherein at least one reagent in liquid form is supplied for the electrochemical measurement.
- the invention relates to an associated arrangement for carrying out the method and furthermore to the use of this arrangement.
- a PCR polymerase chain reaction
- amplification selective DNA amplification
- thermocycler a PCR apparatus which is suitable for quantitative PCR
- electrophoresis apparatus a hybridization station
- optical reader so-called Eppendorf Tubes
- pipetting devices several pipetting devices and a Cooling container for reagents - dependent and must be carried out by trained personnel in compliance with safety regulations with regard to risk of infection, waste disposal or the like.
- volumetric, ie precise, dosages (pipetting) of reagent solutions must be carried out.
- Devices for biochemical analysis are known from the prior art, which according to WO 02/073153 make use of, in particular, silicon-based measuring modules which can be integrated into a chip card.
- the reagents used for the analysis are already integrated in the analysis module in a dry-stored form.
- the aim of the invention is the realization of a low-cost, easy to handle, complete DNA or protein analysis process in a miniaturized cartridge. Based on this, it is an object of the present invention-particularly in such an assay, but not exclusively for this-to carry out an electrochemical measurement in a measuring chamber and, for this purpose, to carry out the measurement sample and the liquid reagents used thereby, which are brought into the measuring chamber by means of pumps. feed bubble-free. In addition, an arrangement for carrying out the method is to be created.
- the invention relates to a method with an associated arrangement for transferring liquids, in particular a sample liquid on the one hand and at least one reagent liquid on the other hand, into a measuring chamber for the purpose of electrochemical measurement, which is suitable for all liquids involved. air-free. This is particularly important when first solid reagents dissolved and so a reagent liquid is prepared.
- sample liquid and reagent liquids which are located in different lines leading to the measuring chamber and separated from each other and from the measuring chamber by air, are brought into the chamber free of air bubbles and thus the actual measurement in the measuring chamber is not disturbed.
- the measurement sample and the reagents are supplied from different sides of the measuring chamber.
- discharge channels for ventilation at the different sides of the measuring chamber are present in the relevant arrangement.
- the invention is therefore applied in particular in the subregion of the cartridge in which the actual detection takes place.
- This detection involves the enzyme-linked DNA hybridization assay.
- the hybridization event mit- labeled by an appropriate enzyme (eg, streptavidin-coupled alkaline phosphatase) and detected by measuring a product (eg, p-aminophenol) produced by the enzymatic activity.
- an appropriate enzyme eg, streptavidin-coupled alkaline phosphatase
- a product eg, p-aminophenol
- the invention can also be used for other measuring procedures on liquid samples which first have to be introduced into a measuring chamber by active pumping together with reagent solutions (eg ELISA ("enzyme-linked immunosorbent assay”) test).
- FIG. 2 shows the top view of a line with recesses for the storage of a dry reagent
- FIGS. 3, 4 show the cross section through a line with recesses for the storage of a dry reagent according to FIG. 2,
- FIG. 2 shows the top view of a line with recesses for the storage of a dry reagent
- FIG. 5 shows a first arrangement in which the lines for the reagents and the test sample are arranged on one side of the measuring chamber
- FIG. 6 shows a second arrangement in which the lines for the test sample and the reagents on different sides of the measuring chamber are arranged.
- FIG. 1 shows a cartridge 100 with a line system which is formed by the microchannels or cavities in a cartridge base body and a cover film closing off the latter.
- the cartridge 100 consists of NEN from a plastic body 101 with the microfluidic system of predetermined structures, which are described by way of example with reference to Figures 2 to 4 below.
- a sample port 102 with adjoining metering section 105 can be seen. This is followed by a channel region 110 for the cell termination and then an area 120 for the PCR. The actual PCR chamber is closed by valves 122, 122 '. The detection of the sample, in particular according to the enzyme-coupled DNA hybridization method, then takes place in the region 130.
- FIG. 1 also shows water ports 103 to 103 '' '. Furthermore, vent ports 104 to 104 '' 'are present.
- FIGS. 2 to 4 show the structure and the structure of the reagent channel 131, 131 'from FIG. 1.
- Each of recesses 132 to 132 6 ' is present, which is suitable for receiving dry reagents 133 to 133 6 'in accordance with FIG 3 are suitable.
- reference numeral 150 denotes a measuring chamber for carrying out an electrochemical measurement, in particular the so-called enzyme-coupled DNA hybridization test.
- an electrochemical measurement in particular the so-called enzyme-coupled DNA hybridization test.
- a hybridized measuring sample on the one hand and certain reagents on the other hand must be introduced into the measuring chamber.
- the actual measuring means and the means for electrical signal detection are not shown in Figures 5 and 6.
- the measuring chamber is shown in FIGS. 5 and 6 as an oval cavity 150 and has accesses on opposite sides 151 and 152, which form the interfaces to the lines.
- the measuring chamber 150 is connected via the access 151 with the Abfallka ⁇ channel Wl.
- the other access 152 is connected in the same way to the waste line W2.
- the waste lines are in contact with the environment via valves. By switching the valves, the flow direction in the fluidic system festge ⁇ sets.
- the valves have a special function if they are only permeable to air and therefore prevent contact of the environment with the reagents and the test sample.
- the sample is conveyed into the measuring chamber 150 via an external pump assigned to the cartridge 100, with any air cushion being advanced in front of the liquid, if necessary. Since the volume of the test sample is greater than that of the measuring chamber, the result is access 151 or 152 to convey the air cushion and the test sample into the waste line W1 or W2.
- a first reagent R 1 is conveyed, so that the air cushion is conveyed into one of the waste channels W 1 or W 2 without entering the measuring chamber 150. Die ⁇ this process is still referred to as venting. By switching the above-mentioned valves is achieved that the reagent then flows through the measuring chamber 150.
- sample liquid and reagent liquids which are located in different lines which lead to the measuring chamber and are separated from one another and from the measuring chamber by air, are introduced into the chamber free of air bubbles and thus the actual measurement in the measuring chamber is not disturbed.
- FIG. 6 the arrangement according to FIG. 5 is modified insofar as the sample line 161 and the lines 162 and 162 'for the reagents are arranged on opposite sides of the measuring chamber 150. Otherwise, the arrangement corresponds to the arrangement according to FIG. 1.
- the required deaeration process can be carried out.
- the arrangement allows the pumping of liquids through the measuring chamber in two directions (back and forth pumping) without the generation of negative pressure (suction). This enhances binding processes that take place within the measuring chamber.
