Abstract

The invention relates to the production of microarray chips for analyzing a large number of individual values, especially DNA or protein microarray chips. According to said method, the substrate (e.g. DNA, protein or other test substances) is homogeneously distributed in a support substance. The support substance, together with the substrate content therein, is transformed into microscopically thin fibers and different fibers are arranged in a bundle. Alternatively, the support substance and the substrate are applied to each other in layers, the combination layer is cut into strips and different strips are combined to form a block. The bundle or block is cut into thin slices crosswise to the longitudinal axis, applied to a solid support and fixed. The support substance is removed and the substrate is immobilized on said support. This method enables microarray chips to be produced with as many substrates as required. The outstanding advantages of the method are as follows: 1. simple production of an almost unlimited number of chips (one bundle/block 10 cm in length produces 1000 slices = chips 100 micrometers thick); 2. very little variation among the chips in a series (the 1000 slices are almost identical in terms of substrate content). The invention hereby provides an efficient and economical means of producing microarray chips for the increasing demand in biomedical research and industry.

Description

Nicht zuletzt mit dem Humanen Genomprojekt, das kurz vor der vollständigen Entschlüsselung der menschlichen Erbinformation steht, findet zur Zeit ein drastischer Umbruch im biomedizinischen Feld statt. In diesem Zusammenhang scheint die sogenannte Mikroarray-Technik als erste technische Neuheit hervorzugehen, die ein Potenzial hat vergleichbar der PCR-Technik in den 80er Jahren (siehe "insight"-Artikel der Nature- Ausgabe vom 15 Juni 2000, Vol. 405, ab Seite 819: Functional genomics).Not least with the Human Genome Project, which is about to be completed Decryption of human genetic information is currently finding a drastic one Upheaval in the biomedical field instead. In this context, the so-called Microarray technology to emerge as the first technical innovation that has potential comparable to the PCR technique in the 80s (see "insight" article by Nature- Edition of June 15, 2000, Vol. 405, from page 819: Functional genomics).

Gegenwärtig wird die Herstellung von sogenannten Mikroarray-Chips für die biomedizinische Forschung vor allem durch zwei Verfahren realisiert: 1. Auf einer Unterlage (Glas oder Membran) werden die Substrate (DNA oder Protein) als Punkte durch mechanisch betriebene feine Metallspitzen aufgetragen; 2. Das Auftragen der Punkte geschieht durch Düsen, die aus den Düsen von Tintenstrahldruckern adaptiert sind.Currently, the production of so-called microarray chips for biomedical Research mainly carried out by two methods: 1. On a base (glass or Membrane), the substrates (DNA or protein) as points by mechanically operated fine metal tips applied; 2. The application of the dots is done through nozzles that come out the nozzles of inkjet printers are adapted.

Beide Verfahren sind zwar in der Lage, Chips mit bis zu Millionen von individuellen Punkten von ca. 10-100 Mikrometer Durchmesser herzustellen, jedoch die Herstellung ist aufwendig aufgrund des Herstellungsprinzips, dass jeder Punkt auf jedem Chip einzeln aufgebracht werden muss. Dieser Nachteil nimmt proportional mit der Anzahl der Substrate (Punkte pro Chip) und der Anzahl der Chips zu. Ein weiterer, qualitativer Nachteil ist die Variabilität der Punkte von Chip zu Chip sogar in derselben Herstellungsserie. Dies ist einerseits durch die mechanische Limitation der Pinspitzen der Auftragungsroboter, andererseits wieder im Herstellungsverfahren (das Auftragen von individuellen Punkten) begründet und beeinträchtigt die Vergleichbarkeit der Resultate.Both methods are capable of chips with up to millions of individual points about 10-100 microns in diameter, but the production is complex due to the manufacturing principle that each point is applied to each chip individually must become. This disadvantage increases proportionally with the number of substrates (points per Chip) and the number of chips. Another qualitative disadvantage is the variability of the Points from chip to chip even in the same production series. On the one hand, this is due to the mechanical limitation of the pin tips of the application robots, on the other hand again in Manufacturing process (the application of individual points) justified and affects the comparability of the results.

Vor diesem Hintergrund ist die Aufgabe der vorliegenden Erfindung ein neues Verfahren für die Herstellung von Mikroarray-Chips. Die Hauptziele der Erfindung sind eine geringe Variabilität der Chips (Qualitätsverbesserung) und eine höhere Ökonomie der Herstellung vor allem von großen Mengen gleicher Chips.Against this background, the object of the present invention is a new method for the production of microarray chips. The main objectives of the invention are minor Variability of the chips (quality improvement) and a higher economy of manufacture before all of large quantities of the same chips.

Bei dem erfindungsgemäßen Verfahren wird als erster Schritt das Substrat in einer Trägersubstanz homogen verteilt. Als Substrat können verschiedenste Testsubstanzen verwendet werden, die in großer Anzahl vorliegen, insbesondere DNS für Genexpressionsanalysen und Proteine für Proteomanalysen, aber auch chemische Substanzen, wie sie bei der Suche nach neuen Medikamenten untersucht werden. Als Trägersubstanz können verschiedenste Substanzen verwendet werden, die eine homogene Mischung des Substrats ermöglichen und nicht das Substrat beschädigen. Die Trägersubstanz ist zunächst formbar, wird dann entweder chemisch (durch eine chemische Reaktion, z. B. Polyacrylamidgel) oder physikalisch (durch Abkühlung, z. B. Paraffin) in einen festen Zustand überführt.In the method according to the invention, the substrate is in a first step Carrier substance distributed homogeneously. A wide variety of test substances can be used as the substrate are used, which are present in large numbers, in particular DNS for Gene expression analysis and proteins for proteome analysis, but also chemical substances, as they are examined when looking for new drugs. As a carrier A wide variety of substances can be used, which a homogeneous mixture of Allow substrate and do not damage the substrate. The carrier is first malleable, then becomes either chemical (through a chemical reaction, e.g. Polyacrylamide gel) or physically (by cooling, e.g. paraffin) to a solid state transferred.

Die Trägersubstanz mit dem darin enthaltenen Substrat wird in Form von mikroskopisch dünnen Fasern (bis zu Durchmessern von unter 100 Mikrometer) gegossen, gezogen oder geschnitten. Fasern mit unterschiedlichen Substaten werden in definierter Anordung gebündelt. Trennmaterial separiert verschiedene Fasern, so dass die Substrate voneinander isoliert sind. Alternativ wird die Trägersubstanz mit dem Substrat in dünnen Schichten (bis zu Dicken von unter 100 Mikrometer) in Lagen aufeinander aufgetragen. Auch hier isolieren Trennschichten Lagen mit verschiedenen Substraten voneinander. Die Gesamtschicht wird in feinen Streifen (bis zu Breiten von unter 100 Mikrometer) geschnitten. Verschiedene Streifen werden zu einem Block vereint. Das Trennmaterial bzw. die Trennschicht besteht entweder aus demselben Trägermaterial ohne Substrat oder aus einem anderen Material, das sich an das Trägermaterial haften lässt.The carrier substance with the substrate contained therein is microscopic cast, drawn or thin fibers (up to diameters of less than 100 microns) cut. Fibers with different substrates are in a defined arrangement bundled. Separating material separates different fibers so that the substrates from each other are isolated. Alternatively, the carrier substance with the substrate in thin layers (up to Thicknesses of less than 100 microns) are applied in layers. Insulate here too Separating layers were layers with different substrates from each other. The entire layer is in cut fine strips (up to widths of less than 100 microns). Different stripes are united into one block. The separating material or the separating layer either exists from the same carrier material without a substrate or from a different material that conforms to the Carrier material adheres.

Das Faserbündel bzw. der Streifenblock wird quer zur Längsachse in dünne Scheiben (bis zu Dicken von unter 100 Mikrometer) geschnitten, auf eine feste Unterlage gebracht und fixiert. Als Unterlagen werden Glasplatten, Metallplatten oder sonstige Platten verwendet, die geeignet sind, das Substrat kovalent oder nicht-kovalent zu immobilisieren. Die Fixation der Scheiben erfolgt chemisch (z. B. durch kovalente Bindung des Trennmaterial an die chemisch vorbehandelte Unterlage) oder physikalisch (z. B. durch Kleben, Pressen oder Aufbrennen). Während oder nach der Fixierung wird die Trägersubstanz entfernt und das Substrat auf der Unterlage immobilisiert. Alternativ wird die Trägersubstanz belassen, dafür das Substrat aus der Trägersubstanz an die Oberfläche gebracht (z. B. durch ein elektrisches Feld bei einem Polyacrylamidgel als Trägersubstanz) und so fixiert.The fiber bundle or strip block is cut into thin slices across the longitudinal axis (up to Thicknesses of less than 100 micrometers), placed on a firm surface and fixed. Glass plates, metal plates or other plates are used as documents are suitable for immobilizing the substrate covalently or non-covalently. The fixation of the Disks are made chemically (e.g. by covalently binding the separating material to the chemical pretreated underlay) or physically (e.g. by gluing, pressing or baking). During or after the fixation, the carrier substance is removed and the substrate on the Immobilized underlay. Alternatively, the carrier substance is left, but the substrate is made out brought to the surface of the carrier substance (e.g. by an electric field at a Polyacrylamide gel as a carrier substance) and thus fixed.

Auf diese Weise können Mikroarray-Chips mit Substraten in der Größenordnung von 106 und mehr in einer Serie von 1000 bis 106 Stückzahlen hergestellt werden. Beispielsweise ist ein Chip mit 104 Substrat-Punkten von 100 Mikrometer Durchmesser und einer Trennschichtdicke von ebenfalls 100 Mikrometer (100 × 2 × 100 Mikrometer)2 = 2 × 2 cm2 = 4 cm2 groß, und bei einer Scheibendicke von 100 Mikrometer gehen aus einem Block von 10 cm Länge 1000 Scheiben, also Chips, hervor. Anzahl und Abmessungen der Substrat-Punkte entsprechen der Dimension bei zur Zeit hergestellten Chips durch andere Herstellungsverfahren.In this way, microarray chips with substrates in the order of 10 6 and more can be produced in a series of 1000 to 10 6 pieces. For example, a chip with 10 4 substrate points of 100 micrometers in diameter and a separating layer thickness of also 100 micrometers (100 × 2 × 100 micrometers) is 2 = 2 × 2 cm 2 = 4 cm 2 in size, and go with a wafer thickness of 100 micrometers from a block of 10 cm length 1000 slices, i.e. chips. The number and dimensions of the substrate points correspond to the dimension in the case of chips currently produced by other production processes.

Die herausragenden Vorteile dieser Methode sind:
The outstanding advantages of this method are:

  • 1. Die ökonomische und schnelle Herstellung von einem Vielfachen der Chipmengen, die nach den bisher üblichen Herstellungsverfahren in einer Serie produziert werden. Beispielsweise ergibt ein Faserbündel von 10 cm Länge 1000 Chips. Diese Zahl erreicht bei den Streifenblöcken eine Million Chips, da bei einer Schichtabmessung von 10 cm × 10 cm parallel 1000 Blöcke verarbeitet werden.1. The economical and rapid production of a multiple of the chip quantities that are produced in a series according to the previously usual manufacturing processes. For example, a fiber bundle of 10 cm in length gives 1000 chips. This number reaches one million chips for the strip blocks, since 1000 blocks are processed in parallel with a layer size of 10 cm × 10 cm.
  • 2. Die geringe Variabilität der Chips einer Serie. Dadurch, dass alle Substrate in dem Faserbündel oder Streifenblock in der Längsachse absolut homogen sind und die einzelnen Substrat-Punkte alle die gleiche Größe haben, hängt die Variabilität unter den Chips einer Serie lediglich von der Präzision des Schneidevorgangs ab. Anders als die individuelle Punkt- Auftragung bei der konventionellen Technik der Mikroarray-Chipherstellung, erfolgt der Schnitt in einem Zug durch den gesamten Block, so dass die Variabilität der individuellen Substrat-Punkte prinzipiell geringer ist.2. The low variability of the chips in a series. Because all substrates in the Fiber bundles or block of strips in the longitudinal axis are absolutely homogeneous and the individual Substrate dots are all the same size, the variability among the chips depends on one Series only depends on the precision of the cutting process. Unlike the individual point Application in the conventional technology of microarray chip production, the Cut in one go through the entire block, allowing the variability of the individual In principle, substrate points is lower.

Die Anwendungsgebiete sind bereits jetzt als immens einzuschätzen, eine genaue Abschätzung des gesamten potenziellen Anwendungsgebiets ist kaum möglich. Angespornt durch das Humane Genomprojekt haben beispielsweise DNS-Mikrochips bereits massiven Einzug in Forschungsinstitute und in die pharmazeutische Industrie erhalten, und weitere Anwendungsbereiche eröffnen sich in rasanter Folge. Ein möglicherweise noch größerer Markt ist voraussichtlich in der klinischen Anwendung für Screening-Untersuchungen.The areas of application can already be assessed as immense, an exact one It is hardly possible to estimate the entire potential area of application. inspired through the Human Genome Project, for example, DNA microchips already have massive ones Getting into research institutes and the pharmaceutical industry, and more Areas of application open up in rapid succession. A possibly bigger one Market is expected to be in clinical use for screening exams.

Die bisherigen Herstellungtechniken sind relativ ineffizient, d. h. gemessen an dem finanziellen und zeitlichen Aufwand ist die Produktion gering. Dadurch ist bereits jetzt die Nachfrage größer als das Angebot, und dies wird sich in den kommenden Jahren verschärfen, vor allem nach der Fertigstellung des Humanen Genomprojekts. Wichtiger noch ist, dass aufgrund des hohen technischen Aufwandes die konventionellen Chips sehr teuer sind und damit die Chips für viele Anwendungen, die wissenschaftlich und medizinisch sinnvoll wären, finanziell unerschwinglich machen. Das hier vorgestellte Verfahren wird die Produktionskosten und damit die Preise drastisch senken können und gleichzeitig eine qualitative Verbesserung der Chips erreichen.The previous manufacturing techniques are relatively inefficient, i. H. measured by that Production is low in financial and time expenditure. This is already the Demand greater than supply, and this will intensify in the coming years, especially after the completion of the human genome project. More importantly, that due to the high technical effort, the conventional chips are very expensive and thus the chips for many applications that make scientific and medical sense would be financially prohibitive. The procedure presented here is the Production costs and thus the prices can drastically reduce and at the same time one achieve qualitative improvement of the chips.
