使用精细颗粒生产生物材料的探针列阵的方法 Fine particles using a method of producing a biomaterial probe arrays

发明背景发明领域本发明涉及在检测肽、蛋白质和DNA,诊断和分析包括DNA的生物材料中使用的探针列阵;和生产同样的探针列阵的方法和装置。 BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to the detection of peptides, proteins and DNA, including diagnosis and analysis of the DNA probe bio-materials used in array; and a method and apparatus for producing the same probe arrays.

此探针检测方法还被用于蛋白质或多肽或各种与它们相互作用的生物材料的分析,并且一种对应于DNA芯片的肽芯片现在正在被使用。 The probe is also a method for detecting or analyzing a protein or polypeptide and their various interactions of biological materials, and one kind of a peptide corresponding to the DNA chip chips are now being used. 在其中一种肽或DNA被固定在一种固体的表面上并在此肽或DNA与一种样品之间进行杂交的这种分离和检测方法,长久以来被称为一种印迹方法,其中靶DNA或同类的东西通过一种被固定在膜上的探针使用放射性标记而被检测。 In a peptide or DNA which is fixed and this separation and detection of hybridization between the peptide or DNA in a sample with the surface of a solid, has long been known as one kind of imprinting method, wherein the target DNA or something similar by means of a probe is immobilized on the membrane is detected using radiolabeled. 然而,在DNA芯片上大量的探针可以被固定在一种诸如玻璃或硅氧烷的固体的表面的一小块区域(1cm2)上,DNA芯片具有只需要小量的样品,并且可以同时使用大量不同探针的优势。 However, in a large number of probes on a DNA chip may be fixed to one of a small area on the surface of the glass, such as silicone or solid (1cm2), a DNA chip having only a small amount of sample and can be used simultaneously advantages of a large number of different probes. 生产DNA芯片的方法大致被分成两组。 The method for producing a DNA chip is generally divided into two groups. 在第一组中,DNA探针是合成的一种基片,每次是通过在一种固体的小节段(0.05mm2到0.2mm2)上的一种光化学反应,使用相同于用于半导体或同类的东西的光学掩蔽技术(Science 251,767,1991)合成的。 In the first group, the DNA probe is a synthetic substrate, each is in the section by means of a photochemical reaction on a solid section (0.05mm2 to 0.2mm2) using the same or similar to the semiconductor for optical something masking technique (Science 251,767,1991) synthesis. 在第二组中,对于个体探针的每一个节段,一种被合成的DNA,PCR-扩增的DNA,或者通过克隆获得的DNA被固定在一种固体的表面的一个小节段上(Nature Biotech 16,27,1998)。 In the second group, one segment for each individual probe a DNA to be synthesized, a PCR-amplified DNA, DNA obtained by cloning or is immobilized on a solid surface of a section segment ( Nature Biotech 16,27,1998). 后者拥有具有所需要的探针的肽芯片或DNA芯片可以相对容易地制造的优势,并且是许多启动公司选择的方法。 The latter has the advantage of having the desired peptide probe chip or a DNA chip can be relatively easily manufactured, and a method of choice in many startup companies.

发明概述一种生物材料的探针芯片,包括DNA,被高度期望用作一种测试工具。 SUMMARY OF THE INVENTION A biological material chip probes, including DNA, was used as a testing tool highly desirable. 然而,就实际而言,以下条件必须满足:(A)可以低成本地制造小量的大量不同的芯片,(B)一种探针可以被均匀地固定;(C)数据是高度可重复的,并且此芯片是可以再用的;并且(D)此芯片可以被加热,从而去除被非特异性吸附的物质。 However, in practical terms, the following conditions must be met: (A) can be manufactured at low cost in a small number of different chips, (B) A probe can be fixed uniformly; (C) data is highly reproducible , and this chip can be reused; and (D) of this chip may be heated to remove non-specifically adsorbed species. 然而,问题依然存在:例如,(a)探针从一个节段到另一个节段是不一致的,(b)生产是劳动密集的,(c)固定化非常精细的分段是不可能的,以及(d)探针不均匀;因为(i)它们是作为液滴被固定在一种固体的表面上的,并且(ii)探针同时被安置和固定。 However, problems remain: for example, (A) a probe from one segment to another segment is not uniform, (b) production is labor intensive, (c) immobilized very fine segments are possible, uneven and (D) a probe; because (i) they are immobilized on a solid surface of the droplets, and (ii) while the probe is positioned and fixed. 而且,(d)与此固体的表面微弱地结合并且一旦加热即可被移去,因为(iii)许多探针芯片通过吸附或同类的作用被固定。 Further, (d) this solid surface bind weakly and can be removed upon heating, as (iii) a number of probe chip is fixed by adsorption or a similar effect.

为了解决上述的问题,探针在固体表面上的固定和这些探针的排列可以被分成两个或更多不同的步骤,从而能够在此固体表面上生产均匀的DNA探针。 To solve the above problem, the arrangement of these probes, and probes fixed on a solid surface may be divided into two or more distinct steps, it is possible to produce a uniform DNA probe on the solid surface. 探针可以经由对热稳定的共价键被固定,因此,被非特异性吸附的物质可以通过加热被适当地去除。 The probe may be secured via a thermally stable covalent bonds, and therefore, the substance is non-specific adsorption can be suitably removed by heating. 排列被用作在其之上固定探针的固体的精细颗粒,从而生产一种具有适当尺寸的节段的探针列阵。 Which arrangement is used as a probe fixed on the solid fine particles, to produce a probe array having segments of appropriate size. 任何想要的探针列阵可以通过交换被排列的具有这些探针的精细颗粒而容易地生产。 Any desired probe array can be easily produced by exchange with these fine particles are arranged in the probe. 镊子可被用来排列具有大约0.3mm的直径的精细颗粒,但是这个方法对于具有小于0.1mm的直径的颗粒将会是困难的。 Tweezers can be used for fine alignment of the particles have a diameter of approximately 0.3mm, but this method for the particles have a diameter of less than 0.1mm would be difficult. 因此,在一个实施方案中,本发明提供一种方法和一种生产一种探针列阵的装置,其中每一个都被容纳于在一种片层之上的一个精细空穴中的精细颗粒被转运并排列在一支毛细管,一块平板上的一个沟槽或者同类的东西中。 Thus, in one embodiment, the present invention provides a method and an apparatus for producing a probe array, each of which is received in a hole on one kind of fine sheets of fine particles It is transported and arranged in a capillary, a plate or a groove on the kind of thing. 在一个备择的方法中,控制精细颗粒,使其作为个体颗粒流进一种液体以转运到一支毛细管中,从而生产一种探针列阵。 In an alternative method, the control of fine particles, the individual particles so as to transport a liquid flow into a capillary tube to thereby produce a probe array. 而且,为了改进测量的重复性,为每一种探针排列了具有多个探针的多个精细颗粒,从而检查测试结果的任何变化以获得高度可靠的数据。 Further, in order to improve measurement repeatability, are arranged a plurality of fine particles having a plurality of probes for each probe, so that any change in checking the test results to obtain highly reliable data.

[实施例7]前面的实施例是一种生产在其中探针珠子被排列在一支毛细管中的一种探针列阵的方法。 [Example 7] The foregoing embodiment is a method for producing one of the probes in the probe beads are arranged in an array of capillaries. 正如在图9a和9b中所说明的一样,这个实施例公开了一种方法和一种装置,在其中首先将珠子排列于一个在一块平板表面上产生的沟槽中,此后将其聚集成一个探针列阵或者将其转运进一支毛细管,从而生产一种探针列阵。 As in Figures 9a and 9b as explained, this embodiment discloses a method and an apparatus in which the beads are arranged in a first groove in a plate produced on the surface, after which aggregated into one probe array or a capillary tube to transport into, thereby producing a probe array. 在图9a和9b中,数字901是一块具有孔的平板,902是一个珠子储存器的一个孔。 In Figures 9a and 9b, numeral 901 is a flat plate having an aperture, a hole 902 is a bead reservoir. 903是一个容纳珠子的空穴,904是一个具有空穴的片层并且通常连接到平板901,905是一个具有排列珠子的沟槽的基础列阵生产支持物,906是一个排列探针珠子的精细沟槽,907是一个具有探针的珠子,908是一个珠子列阵的毛细管。 Receiving hole 903 is a bead, a hole 904 is a slice and typically is connected to the base plates 901,905 having a groove aligned array production of beads support, the probe 906 is arranged in a bead Narrow trench 907 is a bead having a probe, 908 is a capillary bead array. 首先,制备一种在一块平板表面上具有多个沟槽906的珠子列阵生产支持物905。 First, trenches 906 having a plurality of beads in an array on the surface of the production of the support plate 905. 在每一个沟槽中排列具有探针的珠子907,并将它们转运进一种毛细管908或者同类的东西,同时维持它们的排列,此后,将排列在多个沟槽中的珠子引进不同的毛细管中,并用作一种探针列阵。 Beads having probes are arranged in each of the grooves 907 and 908 are transported into the capillary one kind or something similar, while maintaining their alignment, after which the beads are arranged in a plurality of trenches introduce different capillaries and used as one probe array. 将一块与一种具有空穴(901,904)的片层连接在一起的平板放置在珠子列阵生产支持物的顶部,其中这些珠子被俘获在这些空穴中,并将其转运进上文描述的沟槽中。 The plate with one having a cavity (901, 904) connecting together the sheets placed on top of the bead array production support, wherein the beads are trapped in these cavities, and transport it into the above trenches described. 正如图9中所说明的一样,这个具有一种片层的平板具有正交于在珠子列阵生产支持物上的沟槽的孔(珠子储存器902),并且容纳珠子的空穴903是直通空穴,并对此精细沟槽打开。 As illustrated in Figure 9, this one having one sheet of flat plate having a hole (bead reservoir 902) orthogonal to the array of the grooves produced in the support beads, and the beads 903 are received through holes hole, and this fine grooves opened. 此装置的确具有多个沟槽,但是具有不同探针的珠子被注射进此平板上不同的孔中,并被容纳在不同的空穴中。 This apparatus has a plurality of grooves does, but having beads of different probes are injected into separate wells on this plate, and is housed in a different cavity. 使用此与一种片层连接在一起的平板和此具有沟槽的平板,它们紧密接触,但可以彼此滑动。 Using this plate is connected together with one sheet and this plate has grooves, their close contact, but it can slide on each other. 在开始的时候,此片层的空穴903和珠子列阵生产支持物的沟槽906不排成一行。 In the beginning, the hole 903 and the bead array production of this sheet support groove 906 are not aligned. 将具有探针的珠子供应到在具有每一种探针的空穴的片层之上的平板的不同的孔902中。 Beads having different probe supplied to wells of the plates 902 on each sheet having a hole in the probe. 一个珠子落进一个空穴中并被保留在那里,因为在这个状态,此空穴的底部被关闭。 A bead falls into a cavity and retained there, because in this state, the bottom of this hole is closed. 当此片层的空穴和此珠子列阵生产支持物的沟槽被排成一行时,珠子一个接一个地从个体空穴落入沟槽906中。 When the hole in this layer, and the film production support beads array trenches are lined up one behind the beads fall into the trench hole 906 from an individual. 因为不同的珠子列阵从不同的位置落入一个沟槽中,所以各种珠子被保留在一个沟槽中。 Because different beads fall into a groove in the array from different positions, so that the various beads are retained in a groove. 实际上这些珠子被按照与珠子储存器902内的那些珠子相同的间隔放置在具有空穴的片层上。 In fact the beads are placed on a sheet having holes in the same intervals as those of beads within the bead 902 of the reservoir. 在这个实施例中,此间隔是2mm。 In this embodiment, this spacing is 2mm. 在这个实施例中,将总共50个珠子落入此珠子列阵生产支持物的每一个沟槽中。 Each groove in this embodiment, a total of 50 beads fall within this bead array production of the support. 同样,在这个实施例中可以同时生产10珠子列阵,但是这个数目可以按需要增加。 Also in this embodiment the bead array 10 may be produced simultaneously, but this number may be increased as needed. 在落下这些珠子之后,移动此具有空穴903的片层的位置和此珠子列阵生产支持物的沟槽906,从而密封这些沟槽,此后用一种液流将这些珠子引进此毛细管908中。 After dropping the beads, with this movement and the position of the sheet 903 of this hole bead array production support groove 906 to seal the trenches, after which the beads in a liquid stream introducing this capillary 908 . 通过重复以上描述的步骤,可以排列不同种类的探针的数量。 By repeating the above described steps, the number of probes may be arranged in different species.

在这个实施例中,公开了一个一维排列的探针珠子列阵;然而,自然地,通过安排多个数量的这些列阵或通过二维排列这些列阵,可以生产具有更多种探针的探针列阵。 In this embodiment, there is disclosed a probe beads arranged in a one-dimensional array; however, naturally, by arranging a plurality of such arrays, or by the number of the arrays arranged two-dimensionally, can produce more probes the probe array.

[实施例8]在这个实施例中,一种探针珠子列阵支持物包括这些由一块具有一维或二维分布空穴的平板和一个盖玻片组成的单元。 [Example 8] In this embodiment, one probe array support comprises beads of these plates having a one or two dimensional distribution of the holes and the unit composed of a coverslip. 在图10a,10b和10c中,数字1001是一块微量滴定板型的珠子列阵支持物,1002是一个间隔物,1003是制造一种具有一块盖玻片的珠子列阵单元的一个空穴,1004是一个具有探针的珠子,1005是一块盖玻片,1006是一个溶液出口,1007是一个溶液入口,1008是一个激光光束,1009是一个透镜,而1010是一个检测器。 In FIG. 10a, 10b and 10c, the numeral 1001 is a microtiter plate-type bead support array, a spacer 1002, a hole 1003 is a coverslip producing a beads array unit having, 1004 is a probe having a bead, a cover glass 1005, 1006 is an outlet for the solution, a solution inlet 1007, 1008 is a laser beam, a lens 1009, and 1010 is a detector. 这类似一块微量滴定板。 This is similar to a microtiter plate. 从在其中容纳探针珠子的一块滴定板吸入小量的珠子,并将它们分配到平板1001的空穴(单元)1003中。 From a titer plate in which the receiving suction probe beads small beads, and assign them to a hole plate 1001 (unit) 1003. 根据探针的种类将珠子1004分配到位于指定位置的空穴中,从而生产一种微量滴定板型的具有探针珠子的珠子列阵。 Depending on the type of probe beads 1004 assigned to the specified position in the cavity, the probe beads to produce beads having a microtiter plate array type. 在珠子被分配之后,将光学透明并且不干扰荧光或化学发光的测量的盖玻片1005放置在顶部,从而生产一种单元列阵。 After the beads were allocated, optically clear and does not interfere with the fluorescence or chemiluminescence measured coverslips 1005 is placed on top, thereby producing a cell array. 在盖玻片与壁之间分割微量滴定板型单元列阵的单元的间隔,小于珠子的尺寸,以致珠子不能够向外移出。 Dividing the interval microtiter plate type cell array between the glass and the wall of the unit, it is smaller than the size of the beads so that the beads can not be shifted out. 反应溶液或同类的东西可以自由地流过这些单元。 The reaction solution or something similar may flow freely through these units. 为了使用,将这些单元颠倒,从而使此玻璃侧向下。 For use, these units is reversed, so that the lower side of this glass. 在这个情形下,在玻璃表面上的珠子不依赖于这些单元的深度与反应溶液充分地接触,而这些探针与靶进行杂交。 In this case, the glass beads on the surface does not depend on the depth of the reaction solution sufficient contact with these units, and these probe and the target for hybridization.

[发明效果]如上所描述,根据本发明,通过一个简单的程序可以生产大量的肽或DNA探针列阵。 [Effect of the Invention] As described above, according to the present invention, by a simple procedure can produce large amounts of peptide or DNA probe arrays. 在一种固体的表面固定探针的过程和排列探针的过程是分开的,从而这两个过程都可以被优化。 In the process a solid surface of the fixed probe arrangement and process of the probe are separated, so that the two processes can be optimized. 结果,可以生产均一的并且不容易从此固体表面去除的被固定的探针,此后,通过将珠子按照指定的次序排列,可以容易地生产一种具有所需要种类的探针的列阵。 As a result, uniform and not easily produced from the immobilized probe by removing a solid surface and thereafter, the beads are arranged in the order specified, it can be easily produce a probe array having a desired species. 同样,一种精细的探针列阵——这是难于通过常规方法制造的——可以通过减小这些珠子的大小生产。 Also a fine probe array - which is difficult to fabricate by conventional methods - by reducing the size of the beads produced. 可以简单地通过制备所需要的DNA探针,将它们固定在珠子的表面上,并将这些探针珠子安装到一种生产装置上,生产一种具有新成分的探针列阵,这样,任何时间都可以提供使用者所要求的列阵。 By simply preparing the desired DNA probe, they are fixed on the surface of the beads and the beads to install probes producing device, to produce a probe array having a new composition, so that any time can provide array required by the user. 通过排列多个数量的携带相同探针的珠子,可以获得统计平均值以分析重复性和定量性,并可以进行可靠的测量。 By arranging a plurality of beads carrying the same number of probes, a statistical average can be obtained in quantitative analysis and reproducibility, and can be reliably measured. 而且,此反应是快速而高度敏感的,因为反应的表面区域大于被保留在一块平板上的常规DNA芯片或同类的东西的表面。 Further, this reaction is fast and highly sensitive, since the surface area of ​​the reaction is more than the conventional DNA chip retained or something similar surface on a plate. 这些珠子的大小可以在1微米到30微米之间改变,从而,如果需要的话,可以容易地生产高密度探针列阵。 The size of these beads may vary between 1 to 30 microns, so that, if desired, can easily produce a high density probe array. 例如,通过使用6-微米珠子,可以在一支毛细管中将1,500个探针排列在10-mm的长度上,或者如果使用二维探针列阵支持物,就可以将超过1,000,000个探针保留在一个1cm2的区域上。 For example, by using 6-micron beads, may be arranged on a 10-mm length in 1,500 will be a capillary probe, or if a two-dimensional array probe support, can be retained over 1,000,000 probes in a region of 1cm2.

通过一个极其简单的过程,可以生产多个数量的具有相同的探针排列的列阵,因此,这些列阵也适于批量生产。 By a very simple process, it can produce a plurality of arrays having the same number of probe arrangement, therefore, these arrays are also suitable for mass production.
