Description
技术领域
本发明涉及一种试剂输送系统,更具体的,本发明涉及一种设备,用于选择性的将一种或者多种液体试剂输送到例如分析设备的反应或者测试腔。本发明也涉及其中使用的一种不连续的试剂输送单元,同时也涉及用于将一种或者多种液体试剂输送到这样的设备中的反应或者测试腔中的方法。
背景技术
诸如DNA的提取和纯化或者微生物的检测之类的很多生化反应过程,需要通常以精确测量的和/或定时的数量,连续增加一种或者多种(通常多种)试剂到反应或者测试腔,且这些试剂在使用前必须独立保存。然而,假如有在输送前独立存储的要求,利用简单、紧凑和节省成本的设备来以精确测量的和/或定时的数量来提供各种试剂的选择性输送是困难的。在自动测试或者分析设备方面,希望设置过程简单,总体成本、系统维护和操作者投入最小化,这些矛盾的条件使得实际上和商业上更难实现。
尽管有很多已知的包括各种类型的试剂输送系统的测试或者分析设备的商业例子,但是,如果不是全部,大多数也缺乏上述条件中的至少一条或者一些。
发明内容
在本发明的第一方面,提供了一种输送设备,用于选择性地将一种或者多种液体试剂输送到反应或者测试腔,该设备包括:
一个或者多个各自的存储腔,用于容纳一种或者多种液体试剂,且这些存储腔通常设置在反应或者测试腔之上;以及
一柱塞元件,其设置为且可操作为插入选定的存储腔的口部,这样来从该选定的存储腔中将选定的试剂通过从腔的口部溢出的液体的重力转移到通常位于其下面的反应或者测试腔中。
本发明的设备的实施例提供了一种试剂输送系统,当期望时,该系统允许在使用前以精确的剂量和/或时间来独立的试剂存储,而且利用一种便宜、紧凑且容易设置、使用和维护的设备。
已经发现了体现本发明的设备的根本原理为柱塞的使用,该柱塞插入包含液体试剂的存储腔,以引起该试剂的转移,使得该液体从存储腔的口部溢出,且在重力作用下流入通常设置在存储腔下面的反应或者测试腔。
在本发明的第一方面的优选的实际的实施例中,该输送设备形成反应、测试或者分析设备的一部分,特别是自动化设备的一部分,该设备包括所述的反应或者测试腔、通常设置在所述反应或者测试腔上面的所述一个或者多个各自的存储腔,以及所述的柱塞元件和用于控制该柱塞元件的物理运动的控制装置。
该设备还包括加热装置,其设置为控制在所述反应或者测试腔和/或一个或者多个存储腔中的试剂的温度。该加热装置适宜地包括导电的聚合体,如下详细地描述,通过将受控电流穿过该聚合体(物),该聚合体可以被加热。因此,该设备还可以包括用于加热装置的控制装置,诸如计算机控制装置。
该控制装置通常最好包括诸如在现有测试或者分析机器中已知的用于接合和物理移动柱塞的机械装置、合适的硬件,以及编程为根据使用该设备来实施的任何反应、测试或者分析过程来实现柱塞元件的预定运动的软件。接下来要对此作更详细的描述。
本发明的第一方面的输送设备例如可以用于多阶段(定量)分析设备的最终阶段,例如用于执行腺苷酸激酶(AK)扩增分析,以检测食物的细菌污染,其中需要把几种试剂连续输送到包含预先制备样品的测试腔中,以用于AK-噬菌体的终点分析。这样的分析技术的例子在EP-A-0 680 515中描述。作为另一个例子,该输送设备可以用在DNA的提取和纯化中的不连续阶段,其中需要几种不同试剂液体连续输送到单个反应腔。
实际上,通过将反应或者测试腔,以及一个或者多个试剂存储腔设置为一个整体的不连续的单元,上述限定的输送设备在上述范例中的任何一种情况下的使用可以更加方便。
因此,在本发明的第二方面提供了一种包括反应或者测试腔的反应或者测试单元,用于反应或者测试过程,其中一种或者多种液体试剂选择性地输送到反应或者测试腔,该单元还包括一个或者多个各自的存储腔,用于容纳一种或者多种液体试剂,其中该一个或者多个存储腔具有封闭的底部、可打开的或者打开的口部,且通常设置在反应或者测试腔之上。
如果期望,该测试腔和/或存储腔可以设置有加热和/或冷却装置。当测试腔设置有这样的装置时,在需要加热或者冷却或者热循环的测试腔中可以容易地实施反应,诸如扩增反应,例如聚合酶链式反应(PCR)。当存储腔设置有加热和/或冷却装置时,可以用来使试剂以特定的温度输送到测试腔。
特别地,该加热装置包括导电聚合体,例如在WO 98/24548中所述。当电流通过该聚合体时,该聚合体加热。然而,该聚合体较低的热质量意味着当电流停止时也可以确保快速冷却。
这些聚合体是柔性的且便利的,以致它们可以折叠或者成形为紧密接触任何反应容器,包括本发明的测试和/或存储腔。因此,该聚合体可以形成例如围绕该测试和/或存储腔的外层覆盖物(sheath),或者可以与该测试和/或存储腔一体形成。
当测试腔和/或存储腔包括作为其整体部分的导电聚合体时,它们可以由聚合体通过挤出、注模或者类似的技术来制成。或者,该测试腔或者存储腔可以使用组合结构生产,其中,一层导电聚合体在多层制成容器的材料之间介入,或者,其中,反应容器的内表面或者外表面涂覆有该聚合体,或者,其中,该容器主要由涂覆有薄的PCR兼容材料层的聚合体制成。这样的容器可以使用层压和/或诸如化学或者电化学沉积技术之类的沉积来生产,正如本领域中的已有技术。
然而,在一个特定的实施例中,该测试和/或存储腔具有的导电聚合体只和该测试和/或存储腔的一个特定区域整合,具体地,只和含有或者存储有试剂的下面区域整合。这提供了只对试剂的有效加热,而不对腔的其它区域加热。这样的腔可以使用传统的“包覆模制”技术来生产。
包括聚合体作为整体部分的测试或者存储腔可以提供特别紧凑的结构。
在本发明的第二方面的优选的实际的实施例中,该反应或者测试腔和该一个或者多个存储腔由合适的模制塑料材料制成,例如聚丙烯,且最好包含在由合适的模制塑料材料制成的整体外壳中。该外壳最好包括上部的周边壁,该周边壁共同围绕该存储腔的口部,且向上延伸越过该存储腔的口部,以便用作导流片,以引导从该腔中溢出的液体试剂进入其下面的反应或者测试腔。
当该测试或者存储腔包括导电聚合体时,该外壳可以设置有电接触件,当该测试或者存储腔位于外壳中的适当位置时,这些电接触件设置为接触该导电聚合体加热装置。这些接触件适于连接到电源,最好通过自动控制器,诸如计算机,使得在测试或者存储腔中的试剂温度可以自动被控制。如果有必要,也可以包括诸如热电偶之类的温度监测装置,且结果可以反馈到控制装置,这样可以确保精确地获得和/或维持所期望的温度。
该单元可以方便地设置有一个或者多个存储腔,这些存储腔以预定的数量充满选定的试剂,且该腔(多个腔)的口部适于用可穿孔的密封装置密封,诸如传统的薄片密封件。该单元的反应或者测试腔可以设置为空,或者可以包含预先分配数量的固体(例如冻干的)或者液体试剂,该腔同样用其自身相应的保护性密封件密封。
此外,如果期望,在该反应或者测试腔下面可以设置辅助试剂腔,其口部本身用相应的保护性密封件密封,该保护性密封件限定该反应或者测试腔的底部,该辅助腔包含预先分配量的辅助液体或者固体试剂,在整个过程中的所期望阶段,该反应或者测试腔中的内容可以输送到该辅助腔中。在有些情况下,该辅助试剂腔可以悬挂在该反应或者测试腔的底部之上。这样允许另一种试剂包含在该测试腔的底部,只有当该试剂腔的上表面和下表面均被打孔时,该试剂才被包括到反应中。
当柱塞移动进入各腔的口部时,封闭每个上述单元的腔的密封装置最好容易被柱塞元件的尖端打破或者穿孔。因此,最好该柱塞元件的尖端为此目的适当成形。该尖端可以是例如具有尖锐的尖端的圆锥形,和/或其可以例如形成为在其外表面上具有支撑物或者凸缘。在某些实施例中,柱塞的尖端部分甚至可以具有一个或者多个形成在其外表面上的沟槽结构,当柱塞从任何腔中收回时,这些沟槽结构作为用于液体试剂从其中排放的通道。
根据要被输送的试剂的数量,任何数量的试剂存储腔可以结合反应或者测试腔设置。通常,具有多种的试剂,例如,2、3或者4种,但是可以更多,每种试剂从其自身的各自的存储腔输送,这些存储腔最好围绕该反应或者测试腔的周边且通常位于该反应或者测试腔的周边之上对称设置。该存储腔或者每个存储腔的体积(容量)可以根据需要从存储腔输送的试剂的体积独立选择。
根据要实施的反应的特性,被包括的试剂的特性可以很大范围的变化。除了执行所期望的反应所必需的反应物之外,可以包括包含校准或者猝灭剂的腔,在反应期间,也可以在合适的点加入这些校准(标定)或者猝灭剂。
在本发明的使用范围中,术语“通常在...之上”指试剂存储腔(多个腔)相对于反应或者测试腔的位置,意味着该存储腔或者每个存储腔的大部分体积位于该反应或者测试腔的口部的高度之上,换句话说,这样当柱塞插入存储腔中位移而液体从其中溢出时,液体试剂在重力下可以从存储腔的口部流入反应或者测试腔。通常,最好是这样的情况,即,每个存储腔的全部体积都定位在该反应或者测试腔的口部高度之上。
为了使用本发明实现试剂的精确剂量,通常要预定柱塞元件的形状和尺寸连同各自的存储腔的形状和尺寸,柱塞元件移动进入各腔的距离由柱塞控制装置控制。这通常要考虑留在各腔中或者粘附到各腔或者柱塞元件的外表面的剩余试剂的典型数量。
在本发明的实际实现中,该柱塞元件最好设置和控制为以顺序的方式插入包含要被输送的试剂的每个存储腔中,或者从包含要被输送的试剂的每个存储腔中收回。该柱塞元件可以是实心形式或者中空圆柱形杆或者棒的形式,试剂存储腔通常可以是圆柱形支承管的形式。因此,通常该柱塞元件是可移动的,(a)沿着竖立(最好是基本垂直的)轴线,以便液体试剂从它们各自的存储腔移动,且也便于一开始在封闭这些存储腔的密封件上打孔,且最好也(b)在正交(最好基本水平)平面中,以允许它从一个存储腔移动到另一个存储腔,这样其可以用作(可选择的,也具有前述垂直移动或者作为前述垂直移动的替换)搅拌杆,以在该反应或者测试腔(或者如果有的话,甚至是它们下面的辅助试剂腔)中混合试剂。柱塞元件的所有这些移动可以通过前述的控制装置以预定的方式控制。
在柱塞是中空杆(最好是中空圆柱体)的设备形式中,这对于使可收回的磁体插入柱塞是有用的,以便从分析设备的早期阶段收集装载样品的磁珠,其中本发明的输送设备形成该分析设备的一部分。这只是已知的分析技术的一个例子,通过该例子可以使用本发明。
在根据本发明的第二方面不连续的反应或者测试单元的一种可能的形式中,该柱塞元件本身可以设置为该单元的一个组件,例如,作为连接到上部封闭盖子的向下延伸的杆,该封闭盖子在使用前密封整个单元。在这样的情况下,该盖子部分最好设置有这样的装置,通过该装置,一旦该盖子部分从单元分开,它可以由柱塞控制装置物理接合。此外,要使这样的情况实际实现,柱塞元件的尖端下部和盖子部分之间的距离最好大于各试剂存储腔的深度(此外,在有辅助试剂腔位于下面时,该距离大于试剂存储腔和反应或者测试腔本身的组合深度),柱塞元件接附到该盖子部分。在柱塞元件如上所述的具有盖子的实施例中,例如,可以有利于柱塞偏心安装,且有利于盖子形成传送带状的部件,以通过柱塞控制装置接合,从而柱塞在对称设置的试剂腔之间的水平移动可以通过简单地转动盖子元件来实施。
根据本发明的第三方面,本发明还包括一种方法,用于选择性地输送一种或者多种液体试剂到测试或者分析设备中的反应或者测试腔中,该方法包括:
在一个或者多个各自的存储腔中提供一种或者多种液体试剂,这些存储腔通常设置在该反应或者测试腔之上;以及
将柱塞元件插入选择的存储腔的口部,通过从腔的口部溢出的液体重力,使得从存储腔中排出选定的试剂进入通常在下面的反应或者测试腔。
上面限定的方法在以下情况下特别实用,即使用根据上述的本发明的第一和第二方面的任何实施例的输送设备或者反应、测试或者分析设备,或者不连续的反应或者测试单元。

图6是结合本发明的输送设备用于实施腺苷酸激酶分析的设备的简略视图。
具体实施方式
首先参考图1,外壳1由注模聚丙烯制成(这是优选的材料,因为例如与尼龙或者聚乙烯相比,聚丙烯是容易耐高压加热的,且水性液体不容易粘附到聚丙烯上)。外壳1包括下面的中心的容器或者反应腔2,其可以设置为空的,或者可以在使用前包含预先分配的固体或者液体试剂3。用于反应或者分析的样品可以加入该腔2中。具有尖锐的圆锥形尖端4a的柱塞4为实心杆或者中空棒的形式,其在控制硬件和软件(没有显示)的控制下可以水平和垂直移动。
在该示出的实施例中,柱塞4的顶部形成为盖子9,该盖子被用来在使用和/或存储前密封该单元,(如在本说明书的前面一般性讨论的),且也可以用于通过控制柱塞移动的机构接合(例如,通过沟槽(没有显示)或者任何其它合适的已知的这种类型硬件的接附装置)。此外,在该实施例中,柱塞4显示为在顶部具有开口9a的中空圆柱形杆,用于接纳圆柱形的磁体30(也在设备的控制装置的总体控制下)。
在反应容器2之上的是对称的两个存储腔5、6,每个存储腔包含各自的液体试剂,用于在过程中在预定点输送到反应容器2,且每个存储腔由通常的薄片(foil)密封件18密封。在每种试剂需要输送的情况下,柱塞4对准各腔5或者6,然后下降,这样穿孔各密封件18,然后进一步插入腔中,使得从腔中移动(排出)液体试剂,该液体试剂简单地从该腔溢出,且在重力下进入其下面的反应容器2。
柱塞或者棒4在反应容器2中的附加垂直和/或可能的水平移动可以用来将分配的试剂有效地与样品混合。
一独立的、薄片密封的辅助腔7设置在反应腔2之下,以提供存储一种或者多种干燥的辅助试剂8的装置,该辅助试剂可以通过使用棒4来穿孔其自身的保护性密封件18来与反应容器中的试剂混合。
实际上,通过设置各种液体的表面张力有助于降低试剂从各存储腔出来向下进入反应容器的流动。这在某些已知的分析过程中是一种已知的技术,且可以例如通过将合适数量的诸如Triton X-100(商标)之类的表面活性剂包括在液体试剂中或者可以直接包括在该设备的适当的腔中来实现。
图2示出了分析设备的一个例子,其中结合了图1的输送装置。通过例子,图1的单元这里显示为串联的三个腔中的最后的腔,这三个腔形成用后可弃的单元,以实施用于检测食物中的细菌污染的AK-噬菌体分析。第一阶段的容器10包含预先分配的磁珠,磁珠上涂覆有抗体,以特定地捕获目标有机体。使用可以从容器移动到容器的中空柱塞,且该柱塞可以接受其下方中心可收回的磁体,磁珠加上捕获的细菌细胞可以被转移到包含预先分配的洗液的第二阶段容器11,此后转移到本发明的单元的最终腔12,以进行AK分析。只是作为一个例子,该分析的第一部分可以利用称为Kingfisher(商标)的商用分析系统,不包括实验系统。对于AK-噬菌体的终点检测,在本发明的最终单元中的试剂溶液通常是在主反应容器或者腔中的营养液体培养基12、在存储腔之一中的噬菌体13、在另一个存储腔中的ADP14,以及在主反应容器下面的辅助腔中的生物发光试剂15。
通过从存储容器输送已知数量的ATP来代替噬菌体13或者ADP14适于校准(标定)该设备。
附加的试剂可以包括在附加的存储腔或者容器中。例如,在AK-噬菌体分析的情况下,可以期望进一步包括包含猝灭剂的容器,诸如漂白剂或者墨水,其可以停止反应或者猝灭生物发光。这适于设置为在反应的末端输送。
当设备包含多于一个的测试腔时,这可以特别有帮助,因此可以顺序监测多个反应。在一个腔中的光反应的猝灭(quenching)防止光泄漏,以使照度计读取来自接下来的反应的信号。
图3(a)和3(b)示出了本发明的单元的另一个实施例,其几乎与图1相同,但是,替代的,其具有4个试剂存储腔25、26、27和28。图3(a)示出了在腔25中的第一试剂输送到反应容器2中以前的单元,图3(b)示出了后来的单元,预定剂量的第一试剂25”已经输送到反应容器2中,且留下剩余量的25’在该腔中。图4(a)、(b)和(c)以简化示意的形式(但是对于普通技术人员来说,从前面的描述和图中的注解是一目了然的)进一步示出了图1的设备的操作,相应于相同的组件和部件的标号已经在以前的图和上面所述中涉及。
图4(a)示出了在试剂输送过程的开始时的设备。图4(b)示出了已经从腔6输送了预定量6”的试剂到反应容器2以后,柱塞4正要从试剂腔6(其中,正留下预先计算好的剩余试剂量6’)收回时的情况。图4(c)示出了从图4(b)继续的情况,其中,柱塞4已经从存储腔6被收回,替代为位于反应容器2的中心,且可选择地垂直和/或水平移动,以实现反应容器2中的内容物的搅动。
图5示出了柱塞4的一种特定形式。在该实施例中,盖子9是矩形的,以将该特定设备(图6所示)以密封关系安装到下面要描述的结构中。在这样的情况下,该盖子还设置有附加的夹钳孔31,以通过机器使得柱塞组件从一个腔移动到另一个。
图6示出了不连续的设备,用于实施腺苷酸激酶分析,以检测细菌细胞。在这样的情况下,该输送设备合并入支承单元32,该支承单元设置有一系列附加的容器。第一可选的容器33包含试剂培养基34,其可以用来稀释粘性的样品。该容器33由帽35封闭。邻近容器33的是容器36,该容器36为磁珠(bead)提供存储,这些磁珠可以用收集装置来涂覆,诸如细胞或者微生物的抗体,且如果需要,可以是用于特定目标细胞或者有机体的特异性抗体。培养基冲洗液体37设置在又一个相邻的容器38中。
根据本发明的试剂输送设备包括在该单元中。在该实施例中,该输送设备包括用于保持噬菌体13的腔和用于ADP14的腔。营养培养基12提供在主反应容器39中,且冻干的荧光素/荧光素酶试剂40存储在位于主反应容器39之下的薄片密封的辅助腔7中。该单元悬浮在包含缓冲液42的容器41之上。
在图5中所示的柱塞4容纳在另一个容器43中。附加的容器44设置在容器37和反应容器39之间,且也可以容纳柱塞4,并且这样设置,使得当柱塞位于容器中的位置时,延伸的柱塞盖子9覆盖反应容器39。
容器36、38、39、43和44通过金属薄片层压片45来密封。
在使用中,液体或者液化的样品置于样品容器33中。例如,样品可以通过冲洗目前位于容器33中的营养培养基34中的拭子标本来形成。然后移开薄片45,将圆柱形磁体30(图5)放置到柱塞4中,然后用来从容器36收集磁珠。然后,将磁珠磁性地保持在表面上的柱塞4浸入样品液体。移去磁体30,释放磁珠,然后例如使用柱塞4作为搅拌器将磁珠完全与样品混合。在这期间,细胞粘合到磁珠。
然后磁体30放置到柱塞4,这样磁珠再次粘附到柱塞4,柱塞4从试样中移出。然后通过将柱塞4放入容器中且移除磁体30,磁珠被沉积到反应容器39中的培养基12中。对于目标细胞特异的噬菌体13是这样被加入反应混合物中的,即,通过将柱塞4推入包含噬菌体的腔,刺穿覆盖物,且使得噬菌体13溢出进入主反应容器39。然后,将柱塞4放置在容器44中,使得盖子9成为容器39的覆盖物。
然后,持续足够的时间周期来孵育反应混合物,使得噬菌体溶解任何目标细胞。可选的,在这个阶段,使用具有插入其中的磁体30的柱塞4,磁珠可以从试剂容器39中移除。
然后,通过将柱塞4插入反应腔来将ADP14加入反应容器,使得ADP溢出进入反应容器39。再次,如果需要,可以允许该反应进行孵育,柱塞4位于容器44中的位置,这样盖子9封闭容器39,以允许释放腺苷酸激酶将ADP转化为ATP。
在最后的阶段,这样来检测位于反应容器39中的ATP,即,通过将柱塞4推入薄片密封的容器7,释放干燥的荧光素酶和荧光素40,且它们和反应混合物流入缓冲液42。试剂混合在一起,且根据存在的ATP的数量来产生生物荧光信号。这可以通过例如使用照度计来检测。任何信号将指示样品中存在目标细胞。
在这些步骤的每一个中间,可以通过将柱塞浸入容器38中的培养基37中来冲洗。柱塞4的移动适于例如通过使用计算机控制单元来自动实施。
这样,本发明的设备提供一种实施复杂分析的方便的装置。
