Die Erfindung bezieht sich auf eine Anordnung zur integrierten und automatisierten DNA- oder Protein-Analyse in einer einmal verwendbaren Cartridge. Als Cartridge wird dabei eine flache Karte im Scheckkartenformat bezeichnet. Daneben bezieht sich die Erfindung auf die Herstellung einer solchen Cartridge. Schließlich bezieht sich die Erfindung auch auf ein Betriebsverfahren für eine DNA- oder Protein-Analyse unter Verwendung einer solchen Cartridge.The invention relates to an assembly for integrated and automated DNA or protein analysis in a disposable cartridge. Cartridge is a flat card in credit card format. In addition, the invention relates to the production of such a cartridge. Finally, the invention also relates to an operational method for DNA or protein analysis using such a cartridge.

Zur Nukleinsäureanalytik, beispielsweise zur Analytik von weißen Blutzellen aus Vollblut, zwecks Beantwortung von humangenomischen Fragestellungen müssen zunächst in einer ersten Station als Probenvorbereitungsschritt die Zellen aufgebrochen und anschließend die dabei freigesetzte DNA isoliert werden. In einer zweiten Station erfolgt eine PCR (Polymerase Chain Reaction = Polymerase-Ketten-Reaktion) zur selektiven DNA-Vervielfältigung (Amplifikation), um die Konzentration der nachzuweisenden DNA soweit zu erhöhen, dass diese in einer dritten Station nachgewiesen werden kann.For nucleic acid analysis, for example for the analysis of white blood cells from whole blood, in order to answer human-genomic questions, the cells must first be broken open in a first station as a sample preparation step and then the DNA released in the process must be isolated. In a second station, a PCR (Polymerase Chain Reaction = polymerase chain reaction) for selective DNA amplification (amplification), in order to increase the concentration of the DNA to be detected so far that it can be detected in a third station.

Im Labor werden letztere Teilprozesse separat nach bekanntem Stand der Technik durchgeführt. Die vorstehend erläuterten drei Stationen beinhalten jeweils mehrere Arbeitsschritte und werden voneinander unabhängig mit unterschiedlichen Geräten durchgeführt. Die einzelnen Arbeitsschritte erfolgen weitgehend manuell.In the laboratory, the latter sub-processes are carried out separately according to the known state of the art. The three stations explained above each involve several work steps and are performed independently of each other with different devices. The individual steps are largely manual.

Eppendorf-Tubes, mehreren Pipettier-Geräten sowie einem Kühlbehälter für Reagenzien - abhängig und muss von geschultem Personal unter Einhaltung von Sicherheitsvorschriften bezüglich Infektionsgefahr, Abfallentsorgung od. dgl. durchgeführt werden. Insbesondere müssen mehrere volumetrische, d.h. genaue, Dosierungen (Pipettieren) von Reagenzlösungen durchgeführt werden. Solche Arbeitsschritte sind zeitaufwendig und kostenintensiv.The realization of these steps is the presence of laboratory equipment - such as a cell disruption apparatus, a PCR device (so-called Thermocycler), possibly a PCR device, which is for quantitative PCR is suitable, an electrophoresis apparatus, a hybridization station, an optical reader, so-called Eppendorf Tubes, several pipetting devices and a cooling container for reagents - depending and must od trained personnel in compliance with safety regulations regarding risk of infection, waste disposal od . be performed. In particular, multiple volumetric, ie accurate, dosages (pipetting) of reagent solutions must be performed. Such steps are time consuming and costly.

Vom Stand der Technik sind Einrichtungen zur biochemischen Analyse bekannt, die entsprechend der WO 02/073153 A1 Verwendung von insbesondere siliziumbasierten Messmodulen machen, welche in eine Chipkarte integriert werden können. Dabei werden entsprechend der WO 02/072262 A1 bereits die zur Analyse verwendeten Reagenzien in trockengelagerter Form in das Analysemodul integriert.Devices for biochemical analysis are known from the prior art, which correspond to the WO 02/073153 A1 Use of particular silicon-based measurement modules, which can be integrated into a chip card. It will be in accordance with the WO 02/072262 A1 already integrated the reagents used for the analysis in dry stored form in the analysis module.

Davon ausgehend ist Aufgabe der Erfindung die Realisierung eines preisgünstigen, einfach handhabbaren, kompletten DNA-oder Protein-Analyse-Vorganges in einer miniaturisierten Cartridge. Insbesondere sollen folgende Verbesserungen im Vergleich zur Labormethode realisiert werden:

  • Eine vollständige Integration aller Stoffe (evtl. außer Wasser) in einer geschlossenen einmal verwendbaren Cartridge;
  • eine Bevorratung der Reagenzien in einer bei Raumtemperatur lagerstabilen Form;
  • eine automatische Durchführung aller Prozesse in der Cartridge;
  • keine manuellen Arbeitsschritte, außer Injektion der zu analysierenden Probe, z.B. Blut;
  • Kein direkter Kontakt mit gesundheitsgefährdenden Stoffen (Blut und Reagenzien-Abfall verbleiben in der Cartridge);
  • Cartridge-Geometrie erlaubt eine effiziente und schnelle Thermozyklisierung;
  • alle Detektionsvorgänge sollen elektrisch ablaufen und einfach auszulesen sein;
  • die verwendete Cartridge ist klein und kostengünstig herzustellen.
On this basis, the object of the invention is the realization of a low-cost, easy-to-handle, complete DNA or protein analysis process in a miniaturized cartridge. In particular, the following improvements should be realized compared to the laboratory method:
  • A complete integration of all substances (possibly water) in a closed single-use cartridge;
  • storage of the reagents in a storage-stable form at room temperature;

Die Erfindung geht insbesondere von der WO 02/072262 A1 und dem dort genannten weiteren Stand der Technik aus. Dort wird eine Analyseeinrichtung mit in Fluidkanälen trockengelagerten, bei Raumtemperatur stabilen Reagenzien beschrieben, die durch Zuführen von Wasser kurz vor ihrer bestimmungsgemäßen Verwendung in Lösung gebracht werden. Die Erfindung geht weiterhin von der nicht vorveröffentlichten DE 10 2004 021780 A1 und der nicht vorveröffentlichten DE 10 2004 021822 A1 aus. Daneben ist es auch bekannt, speziell elektrisch auslesbare Detektionsmodule zu verwenden.The invention is particularly of the WO 02/072262 A1 and the further prior art mentioned there. There, an analysis device is described with dry-stored in fluid channels, stable at room temperature reagents, which are brought into solution by supplying water shortly before their intended use. The invention continues from the unpublished DE 10 2004 021780 A1 and the not pre-published DE 10 2004 021822 A1 out. In addition, it is also known to use specially electrically readable detection modules.

Demgegenüber ist Gegenstand der Erfindung eine solche einmal verwendbare Cartridge mit einem System aus Mikrokanälen und/oder Mikrokavitäten für einen vorgegebenen Prozessablauf nach der Probenaufnahme, wobei die Cartridge Strukturen zur Aufnahme der Trockenreagenzien aufweist und diesen Strukturen Mittel zur Durchführung sowohl des Zellaufschlusses einerseits und der PCR andererseits, aber auch der elektrochemischen Detektion zugeordnet sind. Insbesondere haben dabei die Kanäle unterschiedliche, problemangepasste Strukturen. Speziell der Aufschlusskanal hat vorteilhafterweise gestufte Querschnitt zur optimalen Benetzung mit dem Trockenreagenz, während die PCR-Kammer und die Elisa-Reagenzkanäle töpfchenförmige Vertiefungen aufweisen.In contrast, the subject of the invention is such a disposable cartridge with a system of microchannels and / or microcavities for a given process flow after sample taking, the cartridge has structures for receiving the dry reagents and these structures means for performing both the cell disruption on the one hand and the PCR on the other , but also associated with electrochemical detection. In particular, the channels have different, problem-adapted structures. Especially the digestion channel advantageously has stepped cross-section for optimal wetting with the dry reagent, while the PCR chamber and Elisa reagent channels have well-shaped wells.

Es kann somit erreicht werden, dass in einem Verfahrensablauf die Zuführung und Aufbereitung der Probe, die DNA-Amplifikation und die eigentliche Detektion der DNA möglich ist.It can thus be achieved that in a procedure the supply and preparation of the sample, the DNA amplification and the actual detection of the DNA is possible.

Durch das erfindungsgemäße System der geometrischen Strukturen in den Mikrokanälen bzw. Mikrokavitäten zur Aufnahme von Trockenreagenzien ergeben sich geeignete Randbedingungen für die DNA-Analyse einerseits und die Protein-Analyse andererseits. Folgende Merkmale und Maßnahmen sind wesentlich:

  • Die im Mikrokanal bzw. in der Mikrokavität eingebrachten Reagenzien sind trockenbare Substanzen mit vernachlässigbarem Dampfdruck. Durch die bei Raumtemperatur stabilen Substanzen bleiben deren Eigenschaften für Zellaufschluss und/oder PCR und/oder Detektion erhalten. Dabei können Gemische aus den Substanzen mit Hilfsstoffen Dünnfilme bilden und können die Gemische mit dünnen Paraffinschichten wasserdicht abgedeckt sein.
The system according to the invention of the geometric structures in the microchannels or microcavities for receiving dry reagents results in suitable boundary conditions for DNA analysis on the one hand and protein analysis on the other hand. The following features and measures are essential:
  • The reagents incorporated in the microchannel or in the microcavity are dryable substances with negligible vapor pressure. The substances which are stable at room temperature retain their properties for cell disruption and / or PCR and / or detection. In this case, mixtures of the substances with auxiliary substances can form thin films and the mixtures can be covered with thin paraffin layers in a watertight manner.

Bei der Erfindung werden die Reagenzien und Hilfsstoffe bereits bei der Herstellung der Cartridge als Trockensubstanzen in Vertiefungen der Cartridgekanäle4 eingebracht. Daraus ergeben sich folgende Vorteile:

  • einfache und präzise Applikation der Reagenzien bei der Herstellung der Cartridge
  • Schutz der Reagenzien beim Befüllen der Reagenzkanäle, d.h. die Reagenzien werden durch einen sog. Wasserflow nicht weggespült, sondern bleiben beim Füllen des gesamten Kanals erhalten. Erst nach dem Befüllen des Kanals lösen sich die Reagenz-Spots über Diffusionsvorgänge auf und es entsteht eine homogene Reagenzlösung.
In the invention, the reagents and auxiliaries are already introduced into depressions of the cartridge channels 4 during the production of the cartridge as dry substances. This results in the following advantages:
  • simple and precise application of the reagents during the production of the cartridge
  • Protection of the reagents during filling of the reagent channels, ie the reagents are not washed away by a so-called water flow, but are retained when filling the entire channel. Only after filling the channel, the reagent spots dissolve via diffusion processes and there is a homogeneous reagent solution.

In einer weiteren besonderen Ausführungsform sind die Vertiefungen in vordefinierten Abständen entlang des Reagenzkanals lokalisiert. Dabei können die Abstände äquidistant sein oder besonders vorteilhaft in variablen Abstandsmustern angeordnet sein.In another particular embodiment, the wells are located at predefined intervals along the reagent channel. The distances can be equidistant or be arranged particularly advantageous in variable spacing patterns.

Die Vertiefungen können vorteilhafterweise mit variablen Trockenreagenzmengen befüllt sein. Durch die Kombination von verschiedenen Trockenreagenzmengen und Abstandsmustern der Vertiefungen können die gewünschten Konzentrationsprofile der fertigen Reagenzlösungen eingestellt werden.The depressions may advantageously be filled with variable amounts of dry reagent. Through the combination of different dry reagent quantities and well spacing patterns, the desired concentration profiles of the final reagent solutions can be adjusted.

Für bestimmte Funktionen wie z.B. Zellaufschluss in Gegenwart von Magnet-Beads und Lyse-Reagenzien ist eine gleichmäßige Verteilung der unlöslichen Komponenten, d.h. der Beads, im Trockenreagenz erforderlich. Dazu werden die Magnet-Beads als Suspension in den Lyse-Kanal dispensiert. Beim Verdampfen des Lösungsmittels wird beobachtet, dass sich die Beads in die Randbereiche des Lyse-Kanals zurückziehen und eine gleichmä-βige Verteilung dadurch nicht gegeben ist. Durch stufenartige Strukturierung des Lyse-Kanal-Querschnittes verteilen sich die Magnet-Beads über die Stufen und eine gleichmäßige Verteilung wird erreicht.For certain functions, such as Cell disruption in the presence of magnetic beads and lysis reagents is a uniform distribution of the insoluble components, i. of the beads, in dry reagent required. For this purpose, the magnetic beads are dispensed as a suspension in the lysis channel. Upon evaporation of the solvent, it is observed that the beads retreat into the peripheral areas of the lysis channel and thus an even distribution is not present. By stepwise structuring of the lysis channel cross-section, the magnetic beads spread over the steps and a uniform distribution is achieved.

Damit mit der erfindungsgemäßen Cartridge gleichermaßen ein Zellaufschluss, eine PCR und ein so genannter DNA-/Protein-ELISA-Test durchgeführt werden kann, ist es vorteilhaft, dass in den Mikrokanälen bzw. Mikrokavitäten Substrate mit DNA-bindenden Eigenschaften, insbesondere die DNA-bindenden Magnet-Beads, vorhanden sind. Dabei können die Lyse-Reagenzien und die Magnet-Beads zusammen in einer einzigen Trockenmatrix enthalten sein. Weiterhin sind in der Karte auch die Reagenzien für einen ELISA-Assay vorhanden. Im Einzelnen werden für das ELISA-Assay zwei Reagenzien benötigt, d.h. als erstes Reagenz ein Label-Enzym und als zweites Reagenz ein Enzym-Substrat.In order that cell disintegration, PCR and a so-called DNA / protein ELISA test can be carried out in the same way with the cartridge according to the invention, it is advantageous that substrates with DNA-binding properties, in particular the DNA-binding properties, are present in the microchannels or microcavities Magnetic beads are present. The lysis reagents and the magnetic beads may be contained together in a single dry matrix. Furthermore, the reagents for an ELISA assay are also present in the card. Specifically, two reagents are required for the ELISA assay, i. the first reagent is a label enzyme and the second reagent is an enzyme substrate.

Insbesondere ist in der Cartridge ein Detektionsmodul zur elektrischen Detektion der Hybridisierungsvorgänge angeordnet. Das Detektionsmodul besteht vorteilhafterweise aus einem Edelmetall/Plastik-Verbund oder einem halbleiterprozessierten Siliziumchip mit Edelmetallelektroden. Für eine elektrische Detektion geeignet sind dabei insbesondere elektrochemische, magnetische oder piezoelektrische Messverfahren.In particular, a detection module for the electrical detection of the hybridization processes is arranged in the cartridge. The detection module advantageously consists of a precious metal / plastic composite or a semiconductor-processed Silicon chip with precious metal electrodes. In particular, electrochemical, magnetic or piezoelectric measuring methods are suitable for electrical detection.

Zur Anwendung der Erfindung der erfindungsgemäßen Cartridge ist insbesondere ein Eingabeport für eine Vollblutprobe vorhanden. Weiterhin sind Mittel zur Zufuhr von Wasser vorhanden, beispielsweise Zufluss-Ports zum Anschluss an eine externe Wasserzufuhr oder ein integriertes Wasserreservoir. In den Mikrokanälen bzw. Mikrokavitäten haben trockene Puffersubstanzen definierte Ionenstärke nach der Wasserzufuhr.In particular, an input port for a whole blood sample is available for use of the invention of the cartridge according to the invention. Furthermore, there are means for supplying water, for example inflow ports for connection to an external water supply or an integrated water reservoir. In the microchannels or microcavities dry buffer substances have defined ionic strength after the water supply.

Bei Anwendung der Erfindung zur Analytik von weißen Blutzellen aus Vollblut sind vorteilhafterweise Mittel zum Mischen einer Vollblutprobe mit Wasser bzw. einer Pufferlösung vorhanden. Dabei sind Mittel zum Durchströmen des mit Lyse-/Bead/Reagenz beschichteten Mikrokanals bzw. Mikrokavität mit Blut bzw. Blut/Wasser- oder Blut/Puffer-Gemische vorhanden.When applying the invention for the analysis of white blood cells from whole blood means are advantageously present for mixing a whole blood sample with water or a buffer solution. In this case, means for flowing through the lysis / bead / reagent coated microchannel or microcavity with blood or blood / water or blood / buffer mixtures are present.

Für die in der erfindungsgemäßen Cartridge bei Anwendung speziell zur DNA-Analyse durchzuführende PCR sind weiterhin Mittel zum Generieren eines Magnetfeldes zum Fixieren des DNA-/Magnetbead-Komplexes in einer PCR-Kavität vorhanden. Für diesen Zweck muss die PCR-Kavität geeignet verschlossen werden können und müssen Mittel zur Thermozyklisierung vorhanden sein.For the PCR to be carried out in the cartridge according to the invention, especially for DNA analysis, there are also means for generating a magnetic field for fixing the DNA / magnetic bead complex in a PCR cavity. For this purpose, the PCR cavity must be suitably sealed and must have means for thermal cycling.

Schließlich ist es bei der erfindungsgemäßen Cartridge wesentlich, dass Mittel zum Lagern von verbrauchtem Probenmaterial und verbrauchten Reagenzien vorhanden sind, die Abfall-Reservoirs bilden. Dabei müssen die Mittel zur keimdichten, zell- bzw. partikelfreien Entlüftung von mindestens einem Abfallreservoir geeignet sein. Zum Auslesen der Cartridge in einem Auslesegerät, das nicht Gegenstand der Erfindung ist, müssen schließlich Mittel zur Fixierung der Cartridge vorhanden sein.Finally, with the cartridge of the present invention, it is essential that there are means for storing spent sample material and spent reagents that form waste reservoirs. In this case, the means for germ-proof, cell or particle-free ventilation of at least one waste reservoir must be suitable. To read the cartridge in a reading device, which is not the subject of the invention, finally, means for fixing the cartridge must be present.
